Administrative access via forged encrypted session cookie
Published Jun 23, 2026 · Updated Jun 23, 2026
Authentication bypass in NetComm NF20MESH R6B031 and earlier allows remote attackers to gain administrative access via a forged session cookie. The web management interface encrypts session cookies with a shared hardcoded AES-256 key, allowing attackers to create cookies that pass authentication checks. Exploitation requires an active legitimate administrator session and grants full control of the management interface.
