Plaintext Password Vulnerability:
Invision Board has been stores restricted forum credentials as plain text embedded in cookie data. These are the forums where you need a password to get access into the forum. If the Invision Board admin 'pass protected' option is activated for a specific forum, on attempted access to the controlled area, the restricted forum password is stored as plaintext in a local cookie. This is dangerous because if an attacker can steal the legit users cookie, then they can gain access to the restricted forum(s). This vulnerability affects all versions of Invision Power Board. Users should not disclose any sensitive information on these "restricted" forums, as they are not secure.
