Vulnerability Information

Severity: Medium
Vulnerability Published: 2006-05-05
Patch Published: 2006-05-23
CVE [?]: CVE-2006-2237
CPE [?]: cpe:/o:canonical:ubuntu_linux:5.04, cpe:/o:canonical:ubuntu_linux:5.10, p-cpe:/a:canonical:ubuntu_linux:awstats

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

AWStats did not properly sanitize the 'migrate' CGI parameter. If the update of the stats via web front-end is allowed, a remote attacker could execute arbitrary commands on the server with the privileges of the AWStats server.

This does not affect AWStats installations which only build static pages.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected awstats package.

Public Exploits
