When files are uploaded into dotCMS via the content API, but before they become content, dotCMS writes the file down in a temporary directory. In the case of this vulnerability, dotCMS does not sanitize the filename passed in via the multipart request header and thus does not sanitize the temporary file's name. This allows an attacker to use a specially crafted request to POST files to dotCMS via the ContentResource API that gets written outside of the dotCMS temporary directory. In the case of this exploit, an attacker can upload a specially crafted .jsp file to the webapp/ROOT directory of dotCMS which can allow for remote code execution.

Artificial intelligence technology can detect the latest wave of Trickbot ransomware and block the attack before it causes damage.

### Impact One can ask for any file located in the classloader using the template API and a path with ".." in it. For example ``` {{template name="../xwiki.hbm.xml"/}} ``` To our knownledge none of the available files of the classloader in XWiki Standard contain any strong confidential data, hence the low confidentiality value of this advisory. ### Patches The issue is patched in versions 14.0 and 13.10.3. ### Workarounds There's no easy workaround for this issue, administrators should upgrade their wiki. ### References * https://jira.xwiki.org/browse/XWIKI-19349 * https://github.com/xwiki/xwiki-platform/commit/4917c8f355717bb636d763844528b1fe0f95e8e2 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira XWiki](https://jira.xwiki.org) * Email us at [security mailing list](mailto:[email protected])

The BN_mod_sqrt() function in OpenSSL versions 1.0.2, 1.1.1, and 3.0, which computes a modular square root, contains a bug that can cause it to loop forever for non-prime moduli.

Red Hat Security Advisory 2022-4845-01 - The zlib packages provide a general-purpose lossless data compression library that is used by many different programs.

This Metasploit module exploits an improper input validation vulnerability in MyBB versions prior to 1.8.30 to execute arbitrary code in the context of the user running the application. The MyBB Admin Control setting page calls the PHP eval function with unsanitized user input. The exploit adds a new setting, injecting the payload in the vulnerable field, and triggers its execution with a second request. Finally, it takes care of cleaning up and removes the setting. Note that authentication is required for this exploit to work and the account must have rights to add or update settings (typically, the myBB administrator role).

Red Hat Security Advisory 2022-4808-01 - The rsyslog packages provide an enhanced, multi-threaded syslog daemon. It supports MySQL, syslog/TCP, RFC 3195, permitted sender lists, filtering on any message part, and fine-grained control over output format. The rsyslog7 packages provide an enhanced, multi-threaded syslog daemon. It supports on-demand disk buffering, reliable syslog over TCP, SSL, TLS and RELP, writing to databases, email alerting, fully configurable output formats, the ability to filter on any part of the syslog message, on-the-wire message compression, and the ability to convert text files to syslog. Issues addressed include a heap overflow vulnerability.
