Detailsinfo

A vulnerability has been found in Extreme Networks ExtremeXOS up to 31.7.3/33.1.99/33.7.0 and classified as problematic. Affected by this vulnerability is an unknown code of the component Authentication. The manipulation with an unknown input leads to a random values vulnerability. The CWE definition for the vulnerability is CWE-330. The product uses insufficiently random numbers or values in a security context that depends on unpredictable numbers. As an impact it is known to affect confidentiality. The summary by CVE is:

ExtremeXOS (EXOS) uses a challenge-response mechanism to authorize access to the privileged debug-mode function. The challenge value is generated using an insufficiently random source, which under certain conditions may allow an attacker to predict the expected response and activate debug-mode without authorization. Depending on device configuration and version, this may enable escalation to root-level access and persistent modification of the device software stack. Exploitation requires either a valid low-privilege account on the device (remote scenario) or physical serial console access (local scenario). This vulnerability is distinct from CVE-2017-14329, which addressed a different issue involving Python script privileges.

The advisory is shared at extremenetworks.com. This vulnerability is known as CVE-2026-8169 since 05/08/2026. The exploitation appears to be difficult. The attack can be launched remotely. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1600.001 for this issue.

Upgrading to version 31.7.4, 32.7.4.15, 33.1.100 or 33.7.1 eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at EUVD (EUVD-2026-46047). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
