Unauthenticated session access via missing endpoint validation
Published Apr 18, 2025 · Updated Apr 22, 2025
Authentication bypass in Elber REBLE310 firmware 5.5.1.R allows remote attackers to access an authenticated session without credentials. The /reble310//indexTH.htm and /reble310//indexR.htm handlers omit session validation and redirect direct requests into an open authenticated session. Network access to the management web interface is sufficient, granting the privileges of the hijacked session and enabling unauthorized access or configuration changes.
