CVE-2023-22296Network attack vector

Browser script execution via unneutralized reflected input

Published Jan 17, 2023 · Updated Apr 4, 2025

Reflected XSS in the MAHO-PBX NetDevancer management screen before 1.11.00 allows remote attackers to execute script in a user's browser. The management screen reflects attacker-supplied input into a page without sufficient output neutralization; public advisories do not identify the parameter. Exploitation is unauthenticated but requires a product user to open the crafted request, causing script execution in that user's browser session.
