Arch Linux Security Advisory ASA-202103-15

Severity: High
Date : 2021-03-25
CVE-ID : CVE-2020-35176
Package : awstats
Type : directory traversal
Remote : Yes
Link : https://security.archlinux.org/AVG-1356

Summary

The package awstats before version 7.8-3 is vulnerable to directory
traversal.

Resolution

Upgrade to 7.8-3.

pacman -Syu “awstats>=7.8-3”

The problem has been fixed upstream but no release is available yet.

Workaround

None.

Description

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.
This issue exists because of an incomplete fix for CVE-2017-1000501 and
CVE-2020-29600.

Impact

A malicious user could access files on the filesystem.
