AWStats: Remote code execution

AWStats: Remote code execution AWStats fails to validate certain input, which could lead to the remote execution of arbitrary code or to the leak of information. awstats 2005-01-25 2009-05-28 77963 81775 remote 6.3-r2 6.3-r2

AWStats is an advanced log file analyzer and statistics generator.

When 'awstats.pl' is run as a CGI script, it fails to validate specific inputs which are used in a Perl open() function call. Furthermore, a user could read log file content even when plugin rawlog was not enabled.

A remote attacker could supply AWStats malicious input, potentially allowing the execution of arbitrary code with the rights of the web server. He could also access raw log contents.

Making sure that AWStats does not run as a CGI script will avoid the issue, but we recommend that users upgrade to the latest version, which fixes these bugs.

All AWStats users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-misc/awstats-6.3-r2"

Note: Users with the vhosts USE flag set should manually use webapp-config to finalize the update.
