** UNSUPPORTED WHEN ASSIGNED ** When using the Chainsaw or SocketAppender components with Log4j 1.x on JRE less than 1.7, an attacker that manages to cause a logging entry involving a specially-crafted (ie, deeply nested) hashmap or hashtable (depending on which logging component is in use) to be processed could exhaust the available memory in the virtual machine and achieve Denial of Service when the object is deserialized. This issue affects Apache Log4j before 2. Affected users are recommended to update to Log4j 2.x. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

The remote Redhat Enterprise Linux 9 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - jetty-server: Cookie parsing of quoted values can exfiltrate values from other cookies (CVE-2023-26049)

  - Jetty is a java based web server and servlet engine. In affected versions 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 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. 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 read into memory).

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to its self-reported version number, the installation of Apache Log4j on the remote host is 1.x and is no longer supported. Log4j reached its end of life prior to 2016. Additionally, Log4j 1.x is affected by multiple vulnerabilities, including :

  - Log4j includes a SocketServer that accepts serialized log events and deserializes them without verifying whether     the objects are allowed or not. This can provide an attack vector that can be exploited. (CVE-2019-17571)

  - Improper validation of certificate with host mismatch in Apache Log4j SMTP appender. This could allow an SMTPS     connection to be intercepted by a man-in-the-middle attack which could leak any log messages sent through that     appender. (CVE-2020-9488)

  - JMSSink uses JNDI in an unprotected manner allowing any application using the JMSSink to be vulnerable if it is     configured to reference an untrusted site or if the site referenced can be accesseed by the attacker.
    (CVE-2022-23302)

Lack of support implies that no new security patches for the product will be released by the vendor. As a result, it is likely to contain security vulnerabilities.
