Linux Distros Unpatched Vulnerability : CVE-2026-26032

medium Nessus Plugin ID 327359

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- The PackagerResolver of Apache Ivy is able to download online artifacts and to (re)package them in a format defined by a packager.xml file. This repackaging is done by an Ant script, which is stored in a subdirectory of the configured buildRoot directory. This subdirectory is calculated based on modules coordinates, like the organisation, name or version. If one of the coordinates contains ../ sequences - which are valid characters for Ivy coordinates in general- it is possible to break out of the configured buildRoot directory where other files can be overwritten. In order to exploit this vulnerability an attacker needs to have access to a packager repository and add or modify the coordinates in ivy.xml files to have such ../ sequences. Users of Apache Ivy 2.0.0 to 2.5.3 (inclusive) should upgrade to Ivy 2.6.0.
(CVE-2026-26032)

Note that Nessus relies on the presence of the package as reported by the vendor.
