WSN Forum 1.3.4 and earlier allows remote attackers to execute arbitrary PHP code via a modified pathname in the pathtoconfig parameter that points to an avatar image that contains PHP code, which is then accessed from prestart.php. NOTE: this issue has been labeled remote file inclusion, but that label only applies to the attack, not the underlying vulnerability.

SQL injection vulnerability in memberlist.php in WSN Forum 1.21 allows remote attackers to execute arbitrary SQL commands via the id parameter in a profile action.
