'Name' => 'Apache Module mod_rewrite LDAP Protocol Buffer Overflow',
|
|
'Description' => %q{
|
|
This module exploits the mod_rewrite LDAP protocol scheme handling
|
|
flaw discovered by Mark Dowd, which produces an off-by-one overflow.
|
|
Apache versions 1.3.29-36, 2.0.47-58, and 2.2.1-2 are vulnerable.
|
|
This module requires REWRITEPATH to be set accurately. In addition,
|
|
the target must have 'RewriteEngine on' configured, with a specific
|
|
'RewriteRule' condition enabled to allow for exploitation.
|
|
|
|
The flaw affects multiple platforms, however this module currently
|
|
only supports Windows based installations.
