  • →Sending any Basic auth credentials to cachemgr.cgi is sufficient to trigger the vulnerability and crash the CGI application. ↗
  • →Attack vectors include invalid Content-Length headers, long POST requests, or crafted authentication credentials sent to cachemgr.cgi. ↗
  • →The vulnerability is only exploitable remotely if httpd is running and cachemgr.cgi is accessible; default RHEL config restricts access to localhost.localdomain only. ↗
  • ·cachemgr.cgi is only exposed if httpd is installed and running alongside squid; squid does not require httpd, so installations without httpd are not remotely exploitable. ↗
  • ·Red Hat Enterprise Linux 5 and 6 ship a version of squid that was not affected because the incomplete CVE-2012-5643 fix was never released for those versions. ↗
  • ·CVE-2013-0189 is specifically caused by a reversed POST data size check in the CVE-2012-5643 patch; a separate crash (free of static buffer) reported later is a distinct regression tracked separately and is NOT part of CVE-2013-0189. ↗
