SQL injection vulnerability in misc.php in DeluxeBB 1.3, and possibly earlier, when magic_quotes_gpc is disabled, allows remote attackers to execute arbitrary SQL commands via the xthedateformat parameter in a register action, a different vector than CVE-2005-2989, CVE-2006-2503, and CVE-2009-1033.

SQL injection vulnerability in newpost.php in DeluxeBB 1.3 and earlier, when magic_quotes_gpc is disabled, allows remote attackers to execute arbitrary SQL commands via the membercookie cookie when adding a new thread.

SQL injection vulnerability in misc.php in DeluxeBB 1.3 and earlier allows remote attackers to execute arbitrary SQL commands via the qorder parameter, a different vector than CVE-2005-2989 and CVE-2006-2503.

SQL injection vulnerability in pm.php in DeluxeBB 1.2 and earlier, when magic_quotes_gpc is disabled, allows remote attackers to execute arbitrary SQL commands via a delete##### parameter in a Delete action, a different vector than CVE-2005-2989.

cp.php in DeluxeBB 1.09 does not verify that the membercookie parameter corresponds to the authenticated member during a profile update, which allows remote authenticated users to change the e-mail addresses of arbitrary accounts via a modified membercookie parameter, a different vector than CVE-2006-4078. NOTE: this can be leveraged for administrative access by requesting password-reset e-mail through a lostpw action to misc.php.

PHP remote file inclusion vulnerability in cp/sig.php in DeluxeBB 1.09 and earlier allows remote attackers to execute arbitrary PHP code via a URL in the templatefolder parameter.

Cross-site scripting (XSS) vulnerability in newpost.php in DeluxeBB 1.08, and possibly earlier, allows remote attackers to inject arbitrary web script or HTML via the subject parameter (aka the topic title field).

DeluxeBB 1.08, and possibly earlier, uses cookies that include the MD5 hash of a password, which allows remote attackers to gain privileges by sniffing or cross-site scripting (XSS) and conduct password guessing attacks.

pm.php (aka the PM system) in DeluxeBB 1.08, and possibly earlier, allows remote attackers to bypass authentication by providing an arbitrary username in the membercookie cookie parameter.

DeluxeBB 1.07 and earlier allows remote attackers to bypass SQL injection protection mechanisms via the login variable and certain other variables, by using lowercase "union select" or possibly other statements that do not match the uppercase "UNION SELECT."
