RHEL 9 : log4j (Unpatched Vulnerability)

medium Nessus Plugin ID 202489

Language:

Synopsis

The remote Red Hat 9 host is affected by multiple vulnerabilities that will not be patched.

Description

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.

 - apache-commons-net: FTP client trusts the host from PASV response by default (CVE-2021-37533)

 - Those using Snakeyaml to parse untrusted YAML files may be vulnerable to Denial of Service attacks (DOS).
 If the parser is running on user supplied input, an attacker may supply content that causes the parser to crash by stack overflow. This effect may support a denial of service attack. (CVE-2022-41854)

 - An infinite recursion is triggered in Jettison when constructing a JSONArray from a Collection that contains a self-reference in one of its elements. This leads to a StackOverflowError exception being thrown. (CVE-2023-1436)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Solution

The vendor has acknowledged the vulnerabilities but no solution has been provided. Refer to the vendor for remediation guidance.
