Open ISES Tickets CVE-2026-48242: Hardcoded MySQL Credentials Exposed

Open ISES Tickets CVE-2026-48242: Hardcoded MySQL Credentials Exposed

The National Vulnerability Database has issued an advisory for CVE-2026-48242, affecting Open ISES Tickets versions prior to 3.44.2. This vulnerability stems from hardcoded MySQL database connection credentials, including host, username, password, and database name, directly embedded within the import_mdb.php file.

These critical credentials were committed to a public repository, making them accessible to anyone reviewing the source code. An attacker can easily obtain valid configuration values that might directly correspond to deployed installations, leading to unauthorized database access. The National Vulnerability Database assigns this a CVSSv3.1 score of 8.1 (HIGH), citing network attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability.

This is a fundamental security failure. Embedding production credentials in public source code is an open invitation for compromise. Organizations using affected versions must assume these credentials are known to adversaries. The attacker’s calculus here is trivial: clone the repo, extract the creds, and pivot directly into the database.

What This Means For You

  • If your organization uses Open ISES Tickets, especially versions prior to 3.44.2, consider your database credentials compromised. Immediately rotate all MySQL credentials associated with these deployments and audit your database logs for any unauthorized access attempts. Patching is critical, but credential rotation is the immediate priority.
