Browser content modification via undisclosed AllMon2 XSS

Published Oct 5, 2025 · Updated Oct 6, 2025

Cross-site scripting in AllMon2 in AllStarLink Supermon 6.0 through 6.2 allows remote attackers to alter browser-rendered content. The CNA identifies AllMon2 but does not disclose the affected request parameter, output sink, or escaping failure. Exploitation requires a user to render attacker-influenced content, and the published impact is limited to low-integrity modification without data disclosure or service interruption.
