Linux Distros Unpatched Vulnerability : CVE-2026-23500

critical Nessus Plugin ID 308164

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.

- Dolibarr is an enterprise resource planning (ERP) and customer relationship management (CRM) software package. In versions prior to 23.0.0 , the ODT to PDF conversion process in odf.php concatenates the MAIN_ODT_AS_PDF configuration constant directly into a shell command passed to exec() without sanitization. An authenticated administrator can inject arbitrary OS commands via this constant using command separators, achieving remote code execution as the web server user when any ODT template is generated. This issue has been fixed in version 23.0.0. (CVE-2026-23500)

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

Solution

There is no known solution at this time.
