CVE-2013-5705 mod_security: bypass of intended rules via chunked requests
Martin Holst Swende discovered a flaw in the way mod_security handled chunked requests. A remote attacker could use this flaw to bypass intended mod_security restrictions, allowing them to send requests containing content that should have been removed by mod_security.
This issue was corrected in mod_security version 2.7.6.
