sapi/cgi/cgi_main.c in PHP before 5.3.13 and 5.4.x before 5.4.3, when configured as a CGI script (aka php-cgi), does not properly handle query strings that lack an = (equals sign) character, which allows remote attackers to cause a denial of service (resource consumption) by placing command-line options in the query string, related to lack of skipping a certain php_getopt for the 'T' case. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-1823.

Security readout for executives and security teams

CVE-2012-2336 is an old PHP CGI issue that can let a remote attacker exhaust server resources. It affects PHP before 5.3.13 and PHP 5.4.x before 5.4.3 when PHP is configured as a CGI script. It matters mainly for legacy systems still exposing php-cgi behavior. Exposure is most likely on legacy web servers running PHP as CGI/php-cgi with PHP versions earlier than 5.3.13 or 5.4.3. The bundle does not identify affected CPEs or non-CGI PHP deployment modes. Treat this as a legacy exposure cleanup item with service-availability risk. It is not KEV-listed in the bundle, but internet-facing php-cgi on affected PHP versions should be remediated because unsupported legacy PHP increases operational risk. Mitigation focus: Upgrade PHP to 5.3.13, 5.4.3, or a vendor-supported fixed package.; Prioritize replacement of unsupported PHP 5.3 and 5.4 installations.; Disable or remove exposed php-cgi configurations where no longer required..
