FreeBSD : wheel -- CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') (65439aa0-f77d-11f0-9821-b0416f0c4c67)

high Nessus Plugin ID 296235

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 65439aa0-f77d-11f0-9821-b0416f0c4c67 advisory.

https://github.com/pypa/wheel/security/advisories/GHSA-8rrh-rw8j-w5fx reports:
wheel is a command line tool for manipulating Python wheel files, as defined in PEP 427. In versions 0.46.1 and below, the unpack function is vulnerable to file permission modification through mishandling of file permissions after extraction. The logic blindly trusts the filename from the archive header for the chmod operation, even though the extraction process itself might have sanitized the path. Attackers can craft a malicious wheel file that, when unpacked, changes the permissions of critical system files (e.g., /etc/passwd, SSH keys, config files), allowing for Privilege Escalation or arbitrary code execution by modifying now-writable scripts. This issue has been fixed in version 0.46.2.

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

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

Solution

Update the affected packages.
