CVE-2026-8169 - ExtremeXOS Debug-Mode Privilege Escalation via Weak PRNG
CVE ID :CVE-2026-8169
Published : July 20, 2026, 6:16 p.m. | 32 minutes ago
Description :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.
Severity: 8.7 | HIGH
