CVE-2026-48218: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Open ISES Tickets
Open ISES Tickets before 3.44.2 contains a reflected cross-site scripting vulnerability in icons/buttons/landb.php that allows authenticated attackers to inject arbitrary JavaScript by passing an unsanitized value through the frm_name and frm_id POST parameters directly into rendered HTML content and inline JavaScript. Attackers can craft a malicious request containing a JavaScript payload that executes in the victim's browser when the response is rendered.
AI Analysis
Technical Summary
CVE-2026-48218 describes a reflected cross-site scripting vulnerability in Open ISES Tickets prior to version 3.44.2. The flaw exists in the icons/buttons/landb.php file where the frm_name and frm_id POST parameters are not properly sanitized before being embedded into the HTML content and inline JavaScript. An authenticated attacker can exploit this by sending a specially crafted request containing JavaScript payloads, leading to script execution in the context of the victim's browser session.
Potential Impact
Successful exploitation allows an authenticated attacker to execute arbitrary JavaScript in the context of a victim's browser, potentially leading to session hijacking, unauthorized actions, or other client-side attacks. The vulnerability requires authentication and user interaction (UI), and does not provide direct system or data compromise without further chained exploits.
Mitigation Recommendations
No official patch or remediation is currently confirmed. Users should upgrade to Open ISES Tickets version 3.44.2 or later once available, as this version is indicated as the fixed version. Until then, apply strict input validation and sanitization on the frm_name and frm_id parameters if possible. Monitor vendor advisories for official fixes and guidance.
