AlmaLinux 9.2 [TuxCare] Security Update: mod_proxy_cluster Multiple Vulnerabilities (ALMALINUX9.2:CLSA-2026:1778858907)

medium Nessus Plugin ID 361425

Synopsis

The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.2 host has a package installed that is affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1778858907 advisory.

 - A flaw was found in the mod_proxy_cluster in the Apache server. This issue may allow a malicious user to add a script in the 'alias' parameter in the URL to trigger the stored cross-site scripting (XSS) vulnerability. By adding a script on the alias parameter on the URL, it adds a new virtual host and adds the script to the cluster-manager page. (CVE-2023-6710)

 - A vulnerability was found in mod_proxy_cluster. The issue is that the <Directory> directive should be replaced by the <Location> directive as the former does not restrict IP/host access as `Require ip IP_ADDRESS` would suggest. This means that anyone with access to the host might send MCMP requests that may result in adding/removing/updating nodes for the balancing. However, this host should not be accessible to the public network as it does not serve the general traffic. (CVE-2024-10306)

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

Solution

Update the affected mod_proxy_cluster package based on the guidance in TuxCare advisory ALMALINUX9.2:CLSA-2026:1778858907.
