AI Analysis

Impact

Open ISES Tickets before version 3.44.2 has a reflected cross‑site scripting flaw in the opena.php script. An authenticated user can supply an arbitrary JavaScript payload through the frm_call GET parameter, which the page outputs without escaping. The injected script runs in the victim’s browser, allowing an attacker to steal session cookies, hijack sessions, or inject unwanted content into the application.

Affected Systems

The flaw affects all Open ISES Tickets releases earlier than 3.44.2. The product distributed under the openises:tickets CNA manager is impacted.

Risk and Exploitability

The CVSS base score of 5.1 indicates a moderate risk. EPSS data is unavailable and the vulnerability is not listed in the CISA KEV catalog. Exploitation requires valid user credentials to construct a malicious URL containing the frm_call parameter; once accessed, the injected script executes in the victim’s browser, compromising the confidentiality and integrity of the session context.
