CVE-2024-4196Network attack vector

Unauthenticated remote command execution

Published Jun 25, 2024 · Updated Oct 1, 2025

Improper input validation in Avaya IP Office Web Control before 11.1.3.1 allows remote attackers to execute commands via a crafted web request. Avaya identifies Web Control request validation as the locus but has not disclosed the affected handler, parameter, or failed validation operation. No authentication or user interaction is required, and successful exploitation grants command execution with confidentiality, integrity, and availability impact.
