A vulnerability in Extreme Networks’ Fabric Engine (VOSS) before 9.3 was discovered. When SD-WAN AutoSense is enabled on a port, it may automatically configure fabric connectivity without validating ISIS authentication settings. The SD-WAN AutoSense implementation may be exploited by malicious actors by allowing unauthorized access to network fabric and configuration data.
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
