Linux Distros Unpatched Vulnerability : CVE-2026-28295

medium Nessus Plugin ID 300158

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.

 - A flaw was found in the FTP GVfs backend. A malicious FTP server can exploit this vulnerability by providing an arbitrary IP address and port in its passive mode (PASV) response. The client unconditionally trusts this information and attempts to connect to the specified endpoint, allowing the malicious server to probe for open ports accessible from the client's network. (CVE-2026-28295)

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

Solution

There is no known solution at this time.
