CVE-2017-7668

Disclosure Date: June 20, 2017
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

Description

The HTTP strict parsing changes added in Apache httpd 2.2.32 and 2.4.24 introduced a bug in token list parsing, which allows ap_find_token() to search past the end of its input string. By maliciously crafting a sequence of request headers, an attacker may be able to cause a segmentation fault, or to force ap_find_token() to return an incorrect value.
