Vbulletin

In vBulletin through 5.3.x, there is an unauthenticated deserialization vulnerability that leads to arbitrary file deletion and, under certain circumstances, code execution, because of unsafe usage of PHP's unserialize() in vB_Library_Template's cacheTemplates() function, which is a publicly exposed API. This is exploited with the templateidlist parameter to ajax/api/template/cacheTemplates.Show less

vBulletin through 5.3.x on Windows allows remote PHP code execution because a require_once call is reachable with an unauthenticated request that can include directory traversal sequences to specify an arbitrary pathname, and because ../ traversal is blocked but ..\ traversal is not blocked. For example, an attacker can make an invalid HTTP request containing PHP code, and then make an index.php?routestring= request with enough instances of ".." to reach an Apache HTTP Server log file.Show less

The media-file upload feature in vBulletin before 3.8.7 Patch Level 6, 3.8.8 before Patch Level 2, 3.8.9 before Patch Level 1, 4.x before 4.2.2 Patch Level 6, 4.2.3 before Patch Level 2, 5.x before 5.2.0 Patch Level 3, 5.2.1 before Patch Level 1, and 5.2.2 before Patch Level 1 allows remote attackers to conduct SSRF attacks via a crafted URL that results in a Redirection HTTP status code.Show less

SQL injection vulnerability in forumrunner/includes/moderation.php in vBulletin before 4.2.2 Patch Level 5 and 4.2.3 before Patch Level 1 allows remote attackers to execute arbitrary SQL commands via the postids parameter to forumrunner/request.php, as exploited in the wild in July 2016.Show less

The vB_Api_Hook::decodeArguments method in vBulletin 5 Connect 5.1.2 through 5.1.9 allows remote attackers to conduct PHP object injection attacks and execute arbitrary PHP code via a crafted serialized object in the arguments parameter to ajax/api/hook/decodeArguments.Show less

Cross-site request forgery (CSRF) vulnerability in the Moderator Control Panel in vBulletin 4.2.2 allows remote attackers to hijack the authentication of administrators for requests that (1) ban a user via the username parameter in a dobanuser action to modcp/banning.php or (2) unban a user, (3) modify user profiles, edit a (4) post or (5) topic, or approve a (6) post or (7) topic via unspecified vectors.Show less

Cross-site scripting (XSS) vulnerability in admincp/apilog.php in vBulletin 4.2.2 and earlier, and 5.0.x through 5.0.5 allows remote authenticated users to inject arbitrary web script or HTML via a crafted XMLRPC API request, as demonstrated using the client name.Show less

SQL injection vulnerability in includes/api/4/breadcrumbs_create.php in vBulletin 4.2.2, 4.2.1, 4.2.0 PL2, and earlier allows remote authenticated users to execute arbitrary SQL commands via the conceptid argument in an xmlrpc API request.Show less

Multiple cross-site scripting (XSS) vulnerabilities in vBulletin 5.1.1 Alpha 9 allow remote attackers to inject arbitrary web script or HTML via (1) the PATH_INFO to privatemessage/new/, (2) the folderid parameter to a private message in privatemessage/view, (3) a fragment indicator to /help, or (4) the view parameter to a topic, as demonstrated by a request to forum/anunturi-importante/rst-power/67030-rst-admin-restore.Show less

The install/upgrade.php scripts in vBulletin 4.1 and 5 allow remote attackers to create administrative accounts via the customerid, htmldata[password], htmldata[confirmpassword], and htmldata[email] parameters, as exploited in the wild in October 2013.Show less
