CVE-2025-24289Network attack vector

Privilege escalation via CSRF-triggered cross-site scripting

Published Jun 29, 2025 · Updated Jun 30, 2025

Cross-site request forgery in Ubiquiti UCRM Client Signup Plugin 1.3.4 and earlier allows remote attackers to escalate privileges. Published sources do not identify the handler or parameter that accepts the cross-site request or explain how its data reaches an executable script context. Exploitation requires the disabled-by-default plugin to be enabled and an Administrator to visit a crafted malicious page, after which attacker-controlled script execution can assume that Administrator's application privileges.
