CVE-2019-4311: Security Bulletin: IBM Security Guardium Big Data Intelligence (SonarG) is affected by an Information Exposure vulnerability

IBM Security Guardium Big Data Intelligence (SonarG) 4.0 uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information. IBM X-Force ID: 161418.

CVE-2019-4339: IBM Security Guardium Big Data Intelligence information disclosure CVE-2019-4339 Vulnerability Report

Directory Traversal in the function http_verify in nostromo nhttpd through 1.9.6 allows an attacker to achieve remote code execution via a crafted HTTP request.

$nostromo: ChangeLog,v 1.241 2022/12/15 19:18:41 hacki Exp $ 2.1 === - Fix a vulnerability reported by Riccardo Krauter @ SoterITSecurity: If nostromo runs non-chrooted, and with the 'homedirs' configuration option enabled (disabled by default), an attacker can exploit a vulnerability to access files or execute programs (as CGI) outside of the server root directory. For that a specific request URL needs to be crafted by the attacker. 2.0 === - Fix compiling on NetBSD by suppressing the -Wall compiler option. Otherwise compiling breaks due to snprintf() truncate warnings. - Fix sizeof(http\_url) to sizeof(http\_urls) for the http\_urls buffer. Had no impact since both buffers anyway have the same size. - Replace SSL\_CTX\_use\_certificate\_file() with SSL\_CTX\_use\_certificate\_chain\_file(), so that the full certificate chain can be verified. - Update to libmy-2.1, which makes libbsd obsolete, and fixes compiling on FreeBSD. 1.9.9 ===== - Stupid me, forgot to bump the version in the last release! 1.9.8 ===== - Fix a potential segfault which can happen during nhttpd startup when reading a malformed comment line in the nhttpd.conf file. This was was caused by a buffer overflow in the libmy-1.8 fparse() function. Therefore upgraded to libmy-1.9 which contains a fix for fparse(). The issue was reported by Christoffer Jerkeby. 1.9.7 ===== - Fix for CVE-2019-16278 discovered by sp0re. Issue: Due to the missing accounting of the '\\r' character in the libmy-1.7 strcutl() function, an attacker can bypass the directory traversal check in the http\_verify() function in a non-chrooted nhttpd server and thus remote execute unauthorized code. Solution: Fix the strcutl() function in libmy-1.8 as described in the libmy ChangeLog: - strcutl(): take account of the '\\r' character when it appears within a string instead of ignoring it. Improved logic and performance diff by Adrian Steinmann Therefore the injected '\\r' characters will now generate an invalid path resulting in a HTTP 404 response. - Fix for CVE-2019-16279 discovered by sp0re. Issue: The missing header count functionality in the http\_header\_comp() function allowed an attacker to transmit more headers than accepted by nhttpd resulting in a buffer overflow in the header array leading to DoS. Solution: Add the missing header count functionality to the http\_header\_comp() function. Transmission of too many headers will now result in a HTTP 413 response as initially intended. - Close the connection after an HTTP 413 response as we are allowed according to RFC 2626 HTTP/1.1 10.4.14. 1.9.6 ===== - Restore original errno value after handling SIGCHLD. Otherwise this could lead to a break out of the main select(2) loop and therefore of unexpected termination of nostromo. Spotted by Adam Wozniak, nice catch! - Change the crypt(3) API, which is used for basic authentication, to accept all supported algorithms not just DES. - Check crypt(3) for returning NULL to prevent the nhttpd process to core dump in this case. - Add server cache for basic authentication credentials to speed up performance. This will save us filesystem access to htpasswd and additional password encryption cpu cycles for crypt(3). - Add MD5, Blowfish-a, and Blowfish-b algorithm to the crypt(1) tool. - Replace rand(3) with arc4random(3) in the crypt(1) tool for OpenBSD, NetBSD, and FreeBSD. - Fix broken BSD authentication method for basic authentication. - Fix several bites to make nostromo compile cleanly on the tested platforms again which are OpenBSD, NetBSD, FreeBSD, and Linux. - Rewrote printenv CGI from perl to shell script. - Add support for SIGHUP configuration reload. - Make a child process use the default signals instead inheriting the parent process signal handler. This fixes some odd issues. - Update copyright year to 2004 - 2016 and add nostromo CVS Id to all files. 1.9.5 ===== - Handle "Location:" field correctly when passed by a CGI. Bug reported by Axel Gonzalez. 1.9.4 ===== - Update copyright year to 2004 - 2011. - Make nostromo compile again by default; Remove -Werror in src/nhttpd makefiles and #include to src/nhttpd/main.c. - Fix a bug where when nostromo doesn't run in chroot mode somebody can access files beyond our htdocs environment by using specific encoded characters in the request URI (security issue). Issue found and reported by RedTeam Pentesting GmbH. - Fix a bug where in certain conditions garbage is written into the access\_log user agent field. - Do proper handling of max. file descriptors and allow to bump the select(2) max. file descriptors limit (FD\_SETSIZE) via the CON define in config.h by dynamically allocating the fd\_sets. 1.9.3 ===== - Fix two err(3) calls which are lacking an \`%s' modifier (security issue). Patch from Simon Kuhnle. - Fix wrong select() / send\_file() looping (resulting in high process load occasionally), by fixing bogus EAGAIN error handling in sys\_write\_a(). - Fix missing \`\`.Ed'' in nhttpd.8 man page. 1.9.2 ===== - Fix a bug where a 403 response is returned instead of a 404 response. Patch from Szabolcs Nagy. - Style diff which fixes spacing from Daniel Ouellet. - Add optional \`\`homedirs\_public'' configuration parameter to restrict access within the home directories. Suggested by Simon Kuhnle. - Add mandatory \`\`serverlisten'' configuration parameter to allow specific interface binding. - Replaced libmy with latest version libmy-1.7. 1.9.1 ===== - Replace off\_t with intmax\_t integer type since problems have been reported with compiling on some 64bit Linux systems. Therefore we remove the GNU compiler option '-D\_FILE\_OFFSET\_BITS=64'. Initial diff received from Kurt Roeckx. - For unused, string based configuration options, use '\\0' instead strlcpy() '0' into the array. It's less disturbing and more straight. Diff received from Szabolcs Nagy. - Don't leave some alias specific buffers uninitialized, because it can happen that we access those later. Bug reported by Szabolcs Nagy. - According to RFC 3875 set the SERVER\_NAME environment variable dynamicly dependend on the "Host:" request header field instead setting it staticly to the configured servername. Bug reported by Szabolcs Nagy. - Fix a bug where a CGI "Status:" request for 403 or 404 caused a corrupt response header. Bug reported by Szabolcs Nagy. - The header field "Host:" is mandatory for HTTP/1.1 client requests. If it doesn't exist return 400 Bad Request instead of further processing the request. Bug reported by Szabolcs Nagy. - Drop MacOSX support. Too many tweaks with recent MacOSX versions for compiling. - Update copyright year to 2004 - 2009. - Fix sys\_log() by replacing syslog() with vsyslog() so the string arguments get passed. While here move from LOG\_DEBUG to LOG\_INFO. - Replaced libmy with latest version libmy-1.6. 1.9 === - Replace server log parameter entries in the man page by syslog(3). 1.8.9 ===== - send all server log messages to syslog(3) instead to our own log file The configuration parameter "logserver" is obsolete therefore and has been removed from nhttpd.conf. Suggested by Matthias-Christian Ott - Make "logpid" and "logaccess" configuration parameters optional, which allows it to disable pid and access log creation. Suggested by Matthias-Christian Ott. - Remove the whole BSD authentication code on non-OpenBSD systems. Diff received from Matthias-Christian Ott. 1.8.8 ===== - Fix a bug where a requested file with size 0 caused us to send an HTTP repsonse in a loop. Bug reported by Kai Hendry. - Fix a bug where a directory request without trailing "/" to a virtual host URL returned a wrong 301-Location field value. Bug reported by Kai Hendry. - Change mime types parsing to the default syntax; extensions are separated by spaces instead by commas. Our default mime types file (conf/mimes) has been changed to the new syntax therefore. - Also check if HTTPS requests do match to our default URL before searching for virtual hosts. 1.8.7 ===== - Fix security issue for none chroot environments reported by Ben Hutchings: Disallow any direct access to upper level directories (..). On occurrence of a "/../" string in the request URI we return 400 Bad Request now. This prevents access to files beyond of the serverroot directory. - Fix a bug reported by Szabolcs Nagy: If a CGI option ends with a "/" don't apply the docindex to it. - If the PID file can't be created also report about the full filename in the error log. Requested by Kai Hendry. 1.8.6 ===== - Handle POST requests with content length 0 correctly, diff received from Georg Wendenburg. 1.8.5 ===== - Added support for SSLv3. - Replaced a strlcpy() with memcpy() because at this point binary data could be involved. Pointed out by Georg Wendenburg. - Added CONTENT\_TYPE CGI env, diff received from Georg Wendenburg. - Quiet down error messages in the server log file by moving some common error messages to the debug mode output. 1.8.4 ===== - If a select(2) error in the main loop is not EINTR, we shutdown the server. EFAULT, EBADF, and EINVAL are not acceptable. - When a connection gets closed FD\_CLR() the write set also in either case. this fix should finally let get us rid from the select(2) EBADF error, and overwrites the EBADF workaround fix from version 1.8.3. 1.8.3 ===== - Fix a Linux tweak with off\_t by adding -D\_FILE\_OFFSET\_BITS=64 to the compiler options. - If a select(2) error in the main loop is not EINTR, close the connection. this avoids endless looping e.g. when EBADF occurs. - Typo corrections for nhttpd.conf-dist and nhttpd.8 from Will Maier. 1.8.2 ===== - Fix wrong version numbers. 1.8.1 ===== - Fixed gcc3 tweak with variable array definition which caused compiliation error on gcc2 platforms. - Replaced libmy with latest version libmy-1.5. 1.8 === - Added homedirs support. - Added basic authentication via BSD authentication. - Moved variable type for filesizes from int to off\_t to enable proper transfers of very large files. - Directory listing files are sorted alphabetical now. - Make our HTML output HTML 4.01 transitional. - Fixed man page typos. 1.7.9 ===== - The rewritten http\_header\_comp() function implemented in version 1.7.7 could lead to a buffer overflow in some circumstances because the arrived header sequence was not checked for its minimum size. On my machines this effect ended up in a immediately process termination. Nasty bug fixed now. While we are at this function we also get rid of strlen() because we already have the current header size saved in our connection structure; safer and faster. - Fixed man page typos. 1.7.8 ===== - CGIs are no longer determined by a CGI alias. nhttpd checks now if a file has the world executable flag set, and if yes the file is handled as a CGI. this allows you to place CGIs anywhere in your document root, and also to use CGIs as index. the cgiroot and cgiindex config options are obsolete therefore and where removed from the configfile. cgi-bin has moved to htdocs/cgi-bin - Use stat(2) S\_IROTH instead of access(2) to check for file permissions, as we have that information already. - Added HTTP\_ACCEPT\_ENCODING CGI env - Simplified debug logging. - Fixed broken permissions checking on directories. - Fixed another binary data handling issue in CGI main loop. - Improved error handling for select(2) in CGI main loop. - On a fatal error at CGI execution send a 500 before exit(3). - Extended man page. 1.7.7 ===== - http\_header\_comp() which checks if a complete header sequence arrived got unreliable because of our new asynchronous connection handling since version 1.7.6. The function is fixed now and as a side effect much more simplified using less resources. 1.7.6 ===== - Rewrote nostromo to handle connections fully asynchronous over one single select(2) now. This change also fixes the problem that slow connections walked into a connection timeout. - The socket send buffer size is now kept to the operating system value by default. It can be changed optional in config.h by the SBS define. - Added debug mode option. - Added IF\_MODIFIED\_SINCE CGI env, diff received from Daniel Hartmeier. - Fixed unterminated childs leftover when parent is killed. - Fixed broken pipeline connection handling. - Fixed http\_chunk() to handle also binary data now. - Fixed double printing of server port in the signature. - Fixed double creation of Location header field for CGIs. - Fixed wrong Location string for 301 responses over SSL non-default port. - Fixed access log variable which could be used uninitialized. - Fixed broken custom responses. on large custom response files, the transfer was aborted. - Disabled chunking for HTTP/1.0 clients. - Disabled case sensitivy for HTTP protocol. - Reorderd configuration file. - Removed a unnecessary getpid(2) when daemonizing. - Replaced signal handlers SIGTERM code with a volatile sig\_atomic\_t flag. - Extended man page. - Improved style / KNF. 1.7.5 ===== - Set SO\_SNDBUF size on accepted client socket, not on the listener socket, because not every tcp/ip implementation supports inheritance. - Set sockets to O\_NONBLOCK to prevent any possible blocks. 1.7.4 ===== - Fixed POST content size limitation of 8KB. POST content can now be unlimited and is handled in the forked CGI process itself. - Removed all setenv(3) and unsetenv(3) functions and set CGI environment vars with execve(2) instead. This has increased the CGI serving performance about the factor 8. - The DOCUMENT\_ROOT CGI environment variable was set wrong in some cases. Bug fixed now. - In some cases the GMT offset was wrong calculated in the access log. Bug fixed now 1.7.3 ===== - Optimized performance and memory usage by source code optimization. - If a CGI post body included binary data the processing was aborted because we could not handle the binary part. Bug fixed now. - If a CGI post body was terminated with '\\r\\n' and some browsers count that to its content length (and some do not, what a mess!) the post was ignored. Bug fixed now - If the defined setuid user was not found, output a custom error instead the getpwnam(3) errno which almost says nothing. - Removed -ansi compile option to follow OpenBSD. - Fixed -pedantic compile option source code quirks. - Replaced libmy with latest version libmy-1.4. - Changed logo URL. - Applied typo diff for man page received from Marc Balmer@. 1.7.2 ===== - Added custom 401, 403, and 404 responses, requested by Marc Winiger. - Added nph CGI support. - Close all file descriptors which do not belong to the child after fork(2). - Replaced recv(2) with read(2) as we do not use flags. - Replaced send(2) with write(2) as we do not use flags. - Check more system calls for EINTR. - If a CGI post body was terminated with '\\r\\n', we did not parsed that and the post was ignored. Bug fixed now. - In some cases we had wrong data transmission because write(2) was not checked for short writes. Bug fixed now. - Fixed SSL memory leak. 1.7.1 ===== - Implemented HEAD method. - If on basic authentication the realm option in a htaccess file could not be parsed, we just kept the last value in the realm variable instead of overwriting it with "unknown realm". Bug fixed now. 1.7 === - Added 206 Partial Content. Forced by Delta. - Added example lines to configuration file how to change default port 80. - Excluded sin6\_len for Linux. - Imported new nostromo logo. - It is possible now to run IPv6 only. - Deny to run nhttpd as root. - Improved SSL handshake. - Main select(2) checks now writefds to cleanly serve partial file sends - Fixed typos and reviewed source code for BSD style. - If 301 Moved Permanently was called with https, we switched back to http because we did not check for the https flag. Bug fixed now. 1.6 === - Added IPv6 support. - Added pid file creation. - Set listener sockets to SO\_REUSEADDR. - Moved a bunch of static environment variables to dynamic ones, because of SSL and IPv6 introduction. - CGI https environment variable was set wrong because asking the wrong ssl flag variable. Bug fixed now. - If running in chroot mode, virtual hosts and aliases where not found because we accessed the full path to the config file. Bug fixed now. - If returning 500 on file send errors, open files where not closed. Bug fixed now. 1.5.1 ===== - chroot mode caused process hang if /dev/null where not found in the chroot environment. Bug fixed now. 1.5 === - Added SSL support. - Added 403 Forbidden, what means that files are checked for read permissions now instead returning 500 Internal Server Error if no access. - Added TODO file. - Corrected and extended man page. - If the content type was unknown the previous content type was sent, which is wrong. Now the html content type will be send per default on unknown content types. - select(2) for header and body read where using the same readset as the master select(2) which is wrong. Using now own readset. 1.4 === - Corrected the man page. - One of three access\_log functions was still logging with two lines per hit. Bug fixed now. 1.3 === - Makefiles have been ported to compile also on NetBSD, FreeBSD, Linux and MacOSX. - Reduced access\_log to one line per hit instead of two. - Filenames including spaces in directory listing wasn't found, because the href entry had no quotes. Bug fixed now. 1.2 === - If a CGI was called which didn't exist, the last called CGI was executed because the responsible variable, which holds the full executable path, wasn't overwritten. bug fixed now. - Replaced libmy with latest version libmy-1.3 (fixes important security issues). - Replaced last strcpy(3) with strlcpy(3). 1.1 === - Increased socket send buffer to avoid send(2) blocking when buffer is full. - In server log removed unnecessary log messages, made the existing ones more specific and added new log messages. - Removed pre-compiler debug informations because they made the source code hard to read and where not really usable in action. 1.0 === - Fixed memory leak. 0.9 === - A wrong if-condition caused the nhttpd parent process to exit(0) if a CGI was called which didn't exist. Bug fixed now. 0.8 === - Nostromo has been rewritten from a fork(2) server to a select(2) server. with this new method no more child forking for file requests is necessary and the server performance increases therefore. - Increased performance by optimizing source code. - Replaced libmy with latest version libmy-1.2 (faster). - Added pre-compiler debug option to config.h. 0.7 === - Sometimes a child process still hung because not all recv(2) was checked for connection timeout. placed select(2) in front of all recv(2) to check timeout. - Fixed wrong version numbering at several places. - Added install script (Install). 0.6 === - Sometimes a child process hung because of blocking recv(2). bug fixed now. - Replaced libmy with latest version libmy-1.1. - Added timestamps to server log file. - Added version option. 0.5 === - nhttpd didn't chroot(2) because chroot(2) where placed before all configuration files could be read. bug fixed now. 0.4 === - libmy had missing #include in flog.c, nsend.c, strlower.c some architectures (e.g. sparc64) complained and stopped at compiling. bug fixed now. 0.3 === - nhttpd didn't handle http control characters (\\r\\n\\r\\n) in POSTs body entity, and blocked at recv(2). bug fixed now. 0.2 === - Changed default configfile path to /var/nostromo/conf/nhttpd.conf. - chdir/chroot will directly done after reading the configfile successfully. - SIGPIPE, SIGHUP, SIGQUIT, SIGALRM will be silently ignored now and don't generate a server log anymore. 0.1 === - Initial version.
