WordPress Trackback Charset Decoding SQL Injection Vulnerability

Vulnerability Assessment Summary
Checks for SQL injection in WordPress

Detailed Explanation for this Vulnerability Assessment

Summary :

The remote web server contains a PHP application that is prone to SQL
injection attacks.

Description :

The version of WordPress on the remote host supports trackbacks in
alternate character sets and decodes them after escaping SQL
parameters. By specifying an alternate character set and encoding
input with that character set while submitting a trackback, an
unauthenticated remote attacker can bypass the application's parameter
sanitation code and manipulate database queries.

Note that exploitation of this issue is only possible when PHP's
mbstring extension is installed, which is apparently the case with the
remote host.
