GLSA-200508-07 : AWStats: Arbitrary code execution using malicious Referrer information
Medium Nessus Plugin ID 19440
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200508-07 (AWStats: Arbitrary code execution using malicious Referrer information)
When using a URLPlugin, AWStats fails to sanitize Referrer URL data before using them in a Perl eval() routine.
A remote attacker can include arbitrary Referrer information in a HTTP request to a web server, therefore injecting tainted data in the log files. When AWStats is run on this log file, this can result in the execution of arbitrary Perl code with the rights of the user running AWStats.
Disable all URLPlugins in the AWStats configuration.
SolutionAll AWStats users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=www-misc/awstats-6.5' Note: Users with the vhosts USE flag set should manually use webapp-config to finalize the update.
