DISPUTED Multiple SQL injection vulnerabilities in MyBB (aka MyBulletinBoard) before 1.6.1 allow remote attackers to execute arbitrary SQL commands via the keywords parameter in a (1) dosearch action to search.php or (2) dostuff action to private.php. NOTE: the vendor disputes this issue, saying "Although this doesn't lead to an SQL injection, it does provide a general MyBB SQL error."

MyBB is a free and open source forum software. In affected versions the Admin CP's Settings management module does not validate setting types correctly on insertion and update, making it possible to add settings of supported type php with PHP code, executed on on Change Settings pages. This results in a Remote Code Execution (RCE) vulnerability. The vulnerable module requires Admin CP access with the Can manage settings? permission. MyBB's Settings module, which allows administrators to add, edit, and delete non-default settings, stores setting data in an options code string ($optionscode; mybbsettings.optionscode database column) that identifies the setting type and its options, separated by a new line character (\n). In MyBB 1.2.0, support for setting type php was added, for which the remaining part of the options code is PHP code executed on Change Settings pages (reserved for plugins and internal use). MyBB 1.8.30 resolves this issue. There are no known workarounds.

MyBB before 1.8.29 allows Remote Code Injection by an admin with the "Can manage settings?" permission. The Admin CP's Settings management module does not validate setting types correctly on insertion and update, making it possible to add settings of supported type "php" with PHP code, executed on Change Settings pages.

MyBB (aka MyBulletinBoard) before 1.6.7 allows remote attackers to obtain sensitive information via a malformed forumread cookie, which reveals the installation path in an error message.

Unspecified vulnerability in MyBB before 1.6.5 has unknown impact and attack vectors, related to an "unparsed user avatar in the buddy list."

Multiple SQL injection vulnerabilities in MyBB (aka MyBulletinBoard) before 1.6.7 allow remote administrators to execute arbitrary SQL commands via unspecified vectors in the (1) user search or (2) Mail Log in the Admin Control Panel (ACP).

moderation.php in MyBB (aka MyBulletinBoard) before 1.4.1 does not properly check for moderator privileges, which has unknown impact and remote attack vectors.

SQL injection vulnerability in misc.php in MyBB (aka MyBulletinBoard) before 1.4.1 allows remote attackers to execute arbitrary SQL commands via a certain editor field.

Multiple cross-site scripting (XSS) vulnerabilities in MyBB (aka MyBulletinBoard) before 1.4.1 allow remote attackers to inject arbitrary web script or HTML via (1) a certain referrer field in usercp2.php, (2) a certain location field in inc/functionsonline.php, and certain (3) tsubject and (4) psubject fields in moderation.php.

Cross-site scripting (XSS) vulnerability in MyBB 1.2.x before 1.2.14 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors, possibly involving search.php.

Cross-site scripting (XSS) vulnerability in MyBB before 1.6.5 allows remote attackers to inject arbitrary web script or HTML via vectors related to "usernames via AJAX."

Cross-site request forgery (CSRF) vulnerability in global.php in MyBB before 1.6.5 allows remote attackers to hijack the authentication of a user for requests that change the user's language via the language parameter.
