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.

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

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.
