CVE-2026-0689 1 Extremenetworks 1 Extremecloud Iq Site Engine 2026-06-17 N/A 4.9 MEDIUM
In ExtremeCloud IQ – Site Engine (XIQ‑SE) before 26.2.10, a vulnerability in the NAC administration interface allows an authenticated NAC administrator to retrieve masked sensitive parameters from HTTP responses. Although credentials appear redacted in the user interface, the application returns the underlying credential values in the HTTP response, enabling an authorized administrator to recover stored secrets that may exceed their intended access. We would like to thank the Lockheed Martin Red Team for responsibly reporting this issue and working with us through coordinated disclosure.
CVE-2025-8679 1 Extremenetworks 1 Extremeguest Essentials 2026-06-17 N/A 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-2025-6235 1 Extremenetworks 1 Extremecontrol 2026-06-17 N/A 6.1 MEDIUM
In ExtremeControl before 25.5.12, a cross-site scripting (XSS) vulnerability was discovered in a login interface of the affected application. The issue stems from improper handling of user-supplied input within HTML attributes, allowing an attacker to inject script code that may execute in a user's browser under specific interaction conditions. Successful exploitation could lead to exposure of user data or unauthorized actions within the browser context.
CVE-2025-6083 1 Extremenetworks 1 Extremecloud Universal Ztna 2026-06-17 N/A 4.3 MEDIUM
In ExtremeCloud Universal ZTNA, a syntax error in the 'searchKeyword' condition caused queries to bypass the owner_id filter. This issue may allow users to search data across the entire table instead of being restricted to their specific owner_id.
