Date: October 25, 2011
Bugs: #386165

An input sanitation flaw in mod_authnz_external allows remote attacker

mod_authnz_external is a tool for creating custom authentication
backends for HTTP basic authentication.
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-apache/mod_authnz_external
< 3.2.6 >= 3.2.6
mysql/mysql-auth.pl in mod_authnz_external does not properly sanitize
input before using it in an SQL query.
A remote attacker could exploit this vulnerability to inject arbitrary
SQL statements by using a specially crafted username for HTTP
authentication on a site using mod_authnz_external.
There is no known workaround at this time.
All Apache mod_authnz_external users should upgrade to the latest
version:
