HTTP: Apache HTTP Server mod_rewrite RewriteLog Command Execution
This signature detects attempts to exploit a known vulnerability in Apache HTTP web server mod_rewrite. The vulnerability is due to a lack of input validation in handling certain escape sequences when writing to the log file. A remote attacker can exploit these vulnerabilities by sending a specially crafted HTTP request. Successful exploitation could result in attacker controlled script command executing.
Extended Description
mod_rewrite.c in the mod_rewrite module in the Apache HTTP Server 2.2.x before 2.2.25 writes data to a log file without sanitizing non-printable characters, which might allow remote attackers to execute arbitrary commands via an HTTP request containing an escape sequence for a terminal emulator.
