YaBB through 2.5.2: 'guestlanguage' Cookie Parameter Local File Include Vulnerability

Directory traversal vulnerability in Yet another Bulletin Board (YaBB) 2.1 and earlier allows remote authenticated users to execute arbitrary Perl code via a .. (dot dot) in the userlanguage profile setting, which sets the userlanguage key of the member hash, and is propagated to the language variable in (1) HelpCentre.pl and (2) ICQPager.pl, (3) the use_lang variable in Subs.pl, and the actlang variable in (4) Post.pl and (5) InstantMessage.pl; as demonstrated by pointing userlanguage to the English folder, modifying English/HelpCentre.lng file to contain Perl statements, and then invoking the help action in YaBB.pl.

CRLF injection vulnerability in Yet another Bulletin Board (YaBB) 2.1 allows remote attackers to obtain administrative access via requests to (1) register.pl or (2) profile.pl that write CRLF sequences to a .vars file. NOTE: this can be leveraged to execute arbitrary code.

Cross-site scripting (XSS) vulnerability in index.php in Yet another Bulletin Board (YaBB) allows remote attackers to inject arbitrary web script or HTML via the categories parameter.

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.

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

Directory traversal vulnerability in ModifyMessage.php in YaBB SE 1.5.4 through 1.5.5b allows remote attackers to delete arbitrary files via a .. (dot dot) in the attachOld parameter.

Multiple SQL injection vulnerabilities in YaBB SE 1.5.4 through 1.5.5b allow remote attackers to execute arbitrary SQL via (1) the msg parameter in ModifyMessage.php or (2) the postid parameter in ModifyMessage.php.

Cross-site scripting vulnerability in YaBB.cgi for Yet Another Bulletin Board (YaBB) 1 Gold SP1 and earlier allows remote attackers to execute arbitrary script as other web site visitors via script in the num parameter, which is not filtered in the resulting error message.

Cross-site scripting vulnerability in Yet Another Bulletin Board (YaBB) 1 Gold SP 1 and earlier allows remote attackers to execute arbitrary script and steal cookies via a message containing encoded Javascript in an IMG tag.

Directory traversal vulnerability in YaBB search.pl CGI script allows remote attackers to read arbitrary files via a .. (dot dot) attack in the "catsearch" form field.
