YaBB SE multiple modules allow SQL injection

yabb-multiple-sql-injection (15354) The risk level is classified as MediumMedium Risk

Description:

YaBB (Yet Another Bulletin Board) is vulnerable to SQL injection, caused by a vulnerability in the ModifyMessage module and in the ModifyMessage2 module. A remote attacker could insert arbitrary SQL code in the $msg variable in a request to the index.php script of the ModifyMessage module, in the $postid variable in a request to the index.php script of the ModifyMessage2 module, or in the $attachOld variable in a request to the index.php script of the ModifyMessage2 module, which would allow the attacker obtain sensitive information, including the user's MD5 password hash and secret question, allowing the attacker to add, modify or delete data in the backend database.


Consequences:
