Multiple SQL injection vulnerabilities in DeluxeBB 1.0 and 1.0.5 allow remote attackers to execute arbitrary SQL commands via the (1) tid parameter to topic.php, the uid parameter to (2) misc.php or (3) pm.php, or the fid parameter to (3) forums.php or (4) newpost.php.

SQL injection vulnerability in misc.php in DeluxeBB 1.06 allows remote attackers to execute arbitrary SQL commands via the name parameter.

PHP remote file inclusion vulnerability in DeluxeBB 1.06 allows remote attackers to execute arbitrary code via a URL in the templatefolder parameter to (1) postreply.php, (2) posting.php, (3) and pm/newpm.php in the deluxe/ directory, and (4) postreply.php, (5) posting.php, and (6) pm/newpm.php in the default/ directory.

Multiple SQL injection vulnerabilities in DeluxeBB 1.06 allow remote attackers to execute arbitrary SQL commands via the (1) hideemail, (2) languagex, (3) xthetimeoffset, and (4) xthetimeformat parameters during account registration.

Multiple cross-site scripting (XSS) vulnerabilities in pm.php in DeluxeBB 1.07 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) subject or (2) to parameters.

SQL injection vulnerability in cp.php in DeluxeBB 1.07 and earlier allows remote attackers to execute arbitrary SQL commands via the xmsn parameter.

Multiple cross-site scripting (XSS) vulnerabilities in DeluxeBB before 1.08 allow remote attackers to inject arbitrary web script or HTML via the (1) membercookie cookie in header.php and the (2) redirect parameter in misc.php.

DeluxeBB 1.07 and earlier does not properly handle a username composed of a single space character, which allows remote authenticated users to login as the "space" user, post as the guest user, and block the ability of an administrator to ban the "space" user.

SQL injection vulnerability in DeluxeBB 1.07 and earlier allows remote attackers to bypass authentication, spoof users, and modify settings via the (1) memberpw and (2) membercookie cookies.

DeluxeBB 1.07 and earlier allows remote attackers to overwrite the (1) _GET, (2) _POST, (3) _ENV, and (4) _SERVER variables via the _COOKIE (aka COOKIE) variable, which can overwrite the other variables during an extract function call, probably leading to multiple security vulnerabilities, aka "pollution of the global namespace."

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."

DeluxeBB 1.06 and earlier, when run on the Apache HTTP Server with the mod_mime module, allows remote attackers to execute arbitrary PHP code by uploading files with double extensions via the fileupload parameter in a newthread action in newpost.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.

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 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.

DeluxeBB 1.3 allows remote attackers to obtain sensitive information via a direct request to a .php file, which reveals the installation path in an error message, as demonstrated by header_html.php.
