CVE-2026-108900 Details
Description
A vulnerability has been found in Exponent CMS up to 3.0.2patch2. Affected is the function userLogin of the file xmlrpc.php of the component XML-RPC. Such manipulation leads to sql injection. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
A SQL injection vulnerability has been identified in Exponent CMS versions through 3.0.2patch2. The issue arises in the XML-RPC component, specifically within the userLogin function of xmlrpc.php. When XML-RPC is enabled, the function improperly handles usernames by concatenating them directly into a SQL query without proper escaping or parameterization. This flaw allows for remote exploitation of the application’s database via crafted XML-RPC requests, injecting malicious SQL that could be executed by the database.
