CVE-2024-24720Network attack vector

User enumeration via divergent password-reset responses

Published Feb 27, 2024 · Updated May 30, 2025

Information disclosure in the Forgot password function in innovaphone PBX before 14r1 allows remote attackers to enumerate valid user accounts. The App Users password-reset flow returns different responses for existing and nonexistent usernames instead of producing an indistinguishable result. No authentication or user interaction is required, and the disclosed data is limited to whether a submitted username exists.
