Cross-site scripting (XSS) vulnerability in YaBB.pl in YaBB 1 GOLD SP 1.3.2 allows remote attackers to inject arbitrary web script or HTML via a hex-encoded to parameter. NOTE: some sources say that the board parameter is affected, but this is incorrect.

Cross-site request forgery (CSRF) vulnerability in YaBB 1 GOLD SP 1.3.2 allows remote attackers to perform unauthorized actions as the administrative user via a link or IMG tag to YaBB.pl that specifies the desired action, id, and moda parameters.

CRLF injection vulnerability in YaBB 1 Gold before 1.3.2 allows remote attackers to modify text file contents via the subject variable.

Unknown vulnerability in Adminedit.pl YaBB 1 Gold before 1.3.2 allows attackers to execute arbitrary code via settings.pl.

YaBB 1 SP 1.3.1 displays different error messages when a user exists or not, which makes it easier for remote attackers to identify valid users and conduct a brute force password guessing attack.

Interpretation conflict in YaBB before 2.1 allows remote authenticated users to inject arbitrary web script or HTML via HTML in a file with a GIF file extension, which causes the HTML to be executed by a victim who views the file in Internet Explorer as a result of CVE-2005-3312. NOTE: it could be argued that this vulnerability is due to a design flaw in Internet Explorer and the proper fix should be in that browser; if so, then this should not be treated as a vulnerability in YaBB.
