| CVE-2026-8169 | 1 Extreme Networks | 1 Switch Engine (exos) | 2026-07-28 | N/A |
| 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. Extreme would like to thank Hadrien Barral (Université Gustave Eiffel) and Georges-Axel Jaloyan (French Ministry of the Interior) for responsible disclosure of their findings. | ||||
| CVE-2026-8170 | 1 Extreme Networks | 1 Switch Engine (exos) | 2026-07-28 | N/A |
| The mv, cp, and rm file utilities exposed within the ExtremeXOS (EXOS) shell environment fail to safely canonicalize paths and follow symbolic links outside of the intended privilege boundary. An attacker with low-privilege CLI access can create a symbolic link that references a privileged filesystem location and then invoke the affected utilities to read, modify, or replace security-critical files outside of their authorized scope. Under certain conditions, this may enable escalation to root-level access and persistent modification of the device software stack. Exploitation is possible remotely by an attacker holding a low-privilege account, or locally via the serial console.

| CVE-2026-9831 | 1 Extreme Networks | 1 Extreme Platform One | 2026-06-01 | 6.3 Medium |
| A race condition in the shared Extreme Platform ONE IAM Gateway API-key authentication path could, under specific high-concurrency traffic conditions, intermittently allow requests authenticated with an Extreme Platform ONE /IAM-issued API key to receive response data for another tenant. The issue was observed through ExtremeCloud IQ/XIQ API endpoints and validated against both XIQ/XAPI and Extreme Platform ONE /Common Services API paths. XIQ-native tokens and standard OAuth/Bearer JWT authentication were not affected. | ||||
| CVE-2025-8679 | 2 Extreme Networks, Extremenetworks | 2 Extremeguest Essentials, Extremeguest Essentials | 2026-01-15 | 9.8 Critical |
| In ExtremeGuest Essentials before 25.5.0, captive-portal may permit unauthorized access via manual brute-force procedure. Under certain ExtremeGuest Essentials captive-portal SSID configurations, repeated manual login attempts may allow an unauthenticated device to be marked as authenticated and obtain network access. Client360 logs may display the client MAC as the username despite no MAC-authentication being enabled. | ||||
| CVE-2025-11192 | 2 Extreme Networks, Extremenetworks | 2 Fabric Engine, Fabric Engine \(voss\) | 2026-01-15 | 8.6 High |
| 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. | ||||
