Ubuntu 5.04 / 5.10 / 6.06 LTS : awstats vulnerability (USN-290-1)
Medium Nessus Plugin ID 27862
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionHendrik Weimer discovered a privilege escalation vulnerability in awstats. By supplying the 'configdir' CGI parameter and setting it to an attacker-controlled directory (such as an FTP account, /tmp, or similar), an attacker could execute arbitrary shell commands with the privileges of the web server (user 'www-data').
This update disables the 'configdir' parameter by default. If all local user accounts can be trusted, it can be reenabled by running awstats with the AWSTATS_ENABLE_CONFIG_DIR environment variable set to a nonempty value.
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.
SolutionUpdate the affected awstats package.
