Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS : AWStats vulnerabilities (USN-4953-1)

critical Nessus Plugin ID 149478

Synopsis

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

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 20.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4953-1 advisory.

- Awstats version 7.6 and earlier is vulnerable to a path traversal flaw in the handling of the config and migrate parameters resulting in unauthenticated remote code execution. (CVE-2017-1000501)

- In AWStats through 7.7, cgi-bin/awstats.pl?config= accepts an absolute pathname, even though it was intended to only read a file in the /etc/awstats/awstats.conf format. NOTE: this issue exists because of an incomplete fix for CVE-2017-1000501. (CVE-2020-29600)

- In AWStats through 7.8, cgi-bin/awstats.pl?config= accepts a partial absolute pathname (omitting the initial /etc), even though it was intended to only read a file in the /etc/awstats/awstats.conf format.
NOTE: this issue exists because of an incomplete fix for CVE-2017-1000501 and CVE-2020-29600.
(CVE-2020-35176)

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

Solution
