ISPConfig contains an authenticated SQL injection vulnerability in the Remote API. The primaryid parameter passed to delete and update API methods is concatenated directly into SQL WHERE clauses without integer casting or parameterized query binding. The built-in SQL injection scanner does not block quote-free boolean payloads and does not reject requests in its default configuration. A remote API user holding any single low-privilege function permission can inject arbitrary SQL to delete or modify records across all tenants in the control panel database and extract arbitrary data via blind boolean inference, including password hashes and client records.

ISPConfig 3.3.0 is vulnerable to Cross Site Scripting (XSS) via the system status webpage.

An issue was discovered in ISPConfig before 3.2.11p1. PHP code injection can be achieved in the language file editor by an admin if adminallowlangedit is enabled.

ISPConfig before 3.2.2 allows SQL injection.

ISPConfig before 3.1.15p3, when the undocumented reverseproxypanelallowed=sites option is manually enabled, allows SQL Injection.

ISPConfig 3.0.5.2 has Arbitrary PHP Code Execution

ISPConfig 3.0.4.3: the "Add new Webdav user" can chmod and chown entire server from client interface.

An unanchored /[a-z]{2}/ regular expression in ISPConfig before 3.1.13 makes it possible to include arbitrary files, leading to code execution. This is exploitable by authenticated users who have local filesystem access.

ISPConfig 3.x before 3.1.9 allows remote authenticated users to obtain root access by creating a crafted cron job.

Multiple cross-site request forgery (CSRF) vulnerabilities in ISPConfig before 3.0.5.4p7 allow remote attackers to hijack the authentication of (1) administrators for requests that create an administrator account via a request to admin/usersedit.php or (2) arbitrary users for requests that conduct SQL injection attacks via the server parameter to monitor/showsysstate.php.

SQL injection vulnerability in monitor/showsysstate.php in ISPConfig before 3.0.5.4p7 allows remote authenticated users with monitor permissions to execute arbitrary SQL commands via the server parameter. NOTE: this can be leveraged by remote attackers using CVE-2015-4119.2.

DISPUTED Multiple PHP remote file inclusion vulnerabilities in ISPConfig 2.2.3 allow remote attackers to execute arbitrary PHP code via a URL in the (1) goinfo[isp][classesroot] parameter in (a) server.inc.php, and the (2) goinfo[server][classesroot] parameter in (b) app.inc.php, (c) login.php, and (d) trylogin.php. NOTE: this issue has been disputed by the vendor, who states that the original researcher "reviewed the installation tarball that is not identical with the resulting system after installtion. The file, where the $goinfo array is declared ... is created by the installer."

DISPUTED PHP remote file inclusion vulnerability in session.inc.php in ISPConfig 2.2.2 and earlier allows remote attackers to execute arbitrary PHP code via a URL in the goinfo[server][classesroot] parameter. NOTE: the vendor has disputed this vulnerability, saying that session.inc.php is not under the web root in version 2.2, and registerglobals is not enabled.
