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 contain a %3D sequence but no = (equals sign) character, which allows remote attackers to execute arbitrary code by placing command-line options in the query string, related to lack of skipping a certain php_getopt for the 'd' case. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-1823.

Security readout for executives and security teams

This is an old but severe PHP CGI flaw. If a public web server runs affected PHP as php-cgi, a remote attacker may be able to turn a crafted URL into PHP command-line options and execute code on the server. Exposure is limited to systems running vulnerable PHP versions configured as a CGI script, also described as php-cgi. Modern PHP deployments or non-CGI SAPIs are not shown as affected by the provided sources. Treat this as critical for any legacy internet-facing PHP CGI estate. The issue is old, but remote code execution on unsupported servers can create direct business impact. Prioritize finding and retiring or patching exposed php-cgi deployments. Mitigation focus: Upgrade PHP to 5.3.13, 5.4.3, or later supported vendor packages.; Confirm operating system vendor packages include the CVE-2012-2311 fix.; Remove public php-cgi exposure where it is not required..
