Arbitrary JavaScript execution via reflected POST input
Published Dec 11, 2024 · Updated Dec 12, 2024
Reflected XSS in Numerix License Server Administration System 1.1_596 allows remote attackers to execute JavaScript via a crafted POST request. The nlslogin.jsp endpoint returns attacker-controlled POST input in its HTML response without neutralization, so the victim's browser executes it. Exploitation requires a victim to follow a malicious link or visit attacker-controlled content; the script runs in the login page's origin.
