critical Nessus Plugin ID 216762

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS / 24.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7297-1 advisory.

 Fabian Bumer, Marcus Brinkmann, and Jrg Schwenk discovered that the transport protocol implementation in ProFTPD had weak integrity checks. An attacker could use this vulnerability to bypass security features like encryption and integrity checks. (CVE-2023-48795)

 Martin Mirchev discovered that ProFTPD did not properly validate user input over the network. An attacker could use this vulnerability to crash ProFTPD or execute arbitrary code. (CVE-2023-51713)

 Brian Ristuccia discovered that ProFTPD incorrectly inherited groups from the parent process. An attacker could use this vulnerability to elevate privileges. (CVE-2024-48651)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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