Vulnerability Assessment Details
AWStats: Arbitrary code execution using malicious Referrer information
Detailed Explanation for this Vulnerability Assessment
The 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
Disable all URLPlugins in the AWStats configuration.
All AWStats users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-www/awstats-6.5"
Note: Users with the vhosts USE flag set should manually use
webapp-config to finalize the update.
Network Security Threat Level: High
