YaBB Forum [ Follow Ups ] [ Post Followup ] [ Discussion Board ] Posted by Bill Russel on May 03, 2004 at 17:08:47: There's a vulnerability in non-SQL version of YaBB forum (I've checked it with YaBB 1 Gold - SP 1.2 written in Perl -- it's not new, but is in use even nowadays). You can input almost anything into .txt file from boards directory. The "subject" form field isn't checked for "\n" symbols, so creating of a thread with such subject: "test of vulnerability" will add to the current board .txt file these strings software Follow Ups: Post A Followup Name: E-Mail: Subject: Re: YaBB Forum Comments: : There's a vulnerability in non-SQL version of YaBB forum (I've checked it with YaBB 1 Gold - SP 1.2 written in Perl -- it's not new, but is in use even nowadays).
