CVE-2023-46271

Unauthenticated critical-function access via missing ah_webui authentication

Published Feb 19, 2025 · Updated Feb 20, 2025

Buffer overflow in Extreme Networks IQ Engine before 10.6r1a and 10.6r2 through 10.6r4 allows network-adjacent attackers to reach ah_webui functions. The CNA identifies the flaw in the TCP port 3009 service but does not disclose the overflowing input or unchecked copy operation; ZDI instead attributes access to missing authentication. No authentication is required, and ZDI states that root code execution requires chaining this access with other vulnerabilities.
