Description:
According to a vendor announcement [0], a vulnerability exists in the
mod_rewrite module of the Apache HTTP Server [1]. Depending on the
manner in which the Apache HTTP Server was compiled, the software
defect may result in a vulnerability which, in combination with
certain types of "RewriteRule" directives in the server configuration
files, could be triggered remotely. The nature of the vulnerability
can be Denial of Service (DoS) or potentially allow arbitrary code
execution. This issue only affects installations using a "RewriteRule"
with the following characteristics: it allows the attacker to control
the initial part of the rewritten URL (for example if the substitution
URL starts with "$1") or the RewriteRule flags do NOT include any of
the flags Forbidden (F), Gone (G), or NoEscape (NE).
This issue has been rated as having important security impact by the
Apache HTTP Server Security Team. The Common Vulnerabilities and
Exposures (CVE) project assigned the id CVE-2006-3747 [2] to the
problem.
