Vulnerability in the Oracle Hyperion Financial Reporting product of Oracle Hyperion (component: Repository). The supported version that is affected is 11.2.13.0.000. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Hyperion Financial Reporting. While the vulnerability is in Oracle Hyperion Financial Reporting, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Hyperion Financial Reporting accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Hyperion Financial Reporting. CVSS 3.1 Base Score 8.5 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:L).

Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Software Foundation Apache MINA. In SFTP servers implemented using Apache MINA SSHD that use a RootedFileSystem, logged users may be able to discover "exists/does not exist" information about items outside the rooted tree via paths including parent navigation ("..") beyond the root, or involving symlinks. This issue affects Apache MINA: from 1.0 before 2.10. Users are recommended to upgrade to 2.10

Use of Java's default temporary directory for file creation in `FileBackedOutputStream` in Google Guava versions 1.0 to 31.1 on Unix systems and Android Ice Cream Sandwich allows other users and apps on the machine with access to the default Java temporary directory to be able to access the files created by the class. Even though the security vulnerability is fixed in version 32.0.0, maintainers recommend using version 32.0.1 as version 32.0.0 breaks some functionality under Windows.

### Impact Servlets with multipart support (e.g. annotated with `@MultipartConfig`) that call `HttpServletRequest.getParameter()` or `HttpServletRequest.getParts()` may cause `OutOfMemoryError` when the client sends a multipart request with a part that has a name but no filename and a very large content. This happens even with the default settings of `fileSizeThreshold=0` which should stream the whole part content to disk. An attacker client may send a large multipart request and cause the server to throw `OutOfMemoryError`. However, the server may be able to recover after the `OutOfMemoryError` and continue its service -- although it may take some time. A very large number of parts may cause the same problem. ### Patches Patched in Jetty versions * 9.4.51.v20230217 - via PR #9345 * 10.0.14 - via PR #9344 * 11.0.14 - via PR #9344 ### Workarounds Multipart parameter `maxRequestSize` must be set to a non-negative value, so the whole multipart content is limited (although still read...

Nonstandard cookie parsing in Jetty may allow an attacker to smuggle cookies within other cookies, or otherwise perform unintended behavior by tampering with the cookie parsing mechanism. If Jetty sees a cookie VALUE that starts with `"` (double quote), it will continue to read the cookie string until it sees a closing quote -- even if a semicolon is encountered. So, a cookie header such as: `DISPLAY_LANGUAGE="b; JSESSIONID=1337; c=d"` will be parsed as one cookie, with the name `DISPLAY_LANGUAGE` and a value of `b; JSESSIONID=1337; c=d` instead of 3 separate cookies. ### Impact This has security implications because if, say, `JSESSIONID` is an `HttpOnly` cookie, and the `DISPLAY_LANGUAGE` cookie value is rendered on the page, an attacker can smuggle the `JSESSIONID` cookie into the `DISPLAY_LANGUAGE` cookie and thereby exfiltrate it. This is significant when an intermediary is enacting some policy based on cookies, so a smuggled cookie can bypass that policy yet still be seen by ...

Jetty is a java based web server and servlet engine.

An attacker client may send a large multipart request and cause the server to throw `OutOfMemoryError`.

This issue has been patched in versions 9.4.51, 10.0.14, and 11.0.14. Users are advised to upgrade. Users unable to upgrade may set the multipart parameter `maxRequestSize` which must be set to a non-negative value, so the whole multipart content is limited (although still re...
