What is CVE-2025-46633?

The Tenda RX2 Pro web management portal is susceptible to a vulnerability that allows an attacker to intercept and decrypt sensitive information during transmission. The issue arises from the cleartext transmission of a symmetric AES key following successful authentication, which could lead to exposure of confidential data. Specifically, the Initialization Vector (IV) used in the AES encryption is static, facilitating potential exploitation by attackers who are able to acquire and analyze the unprotected traffic.
