CVE-2024-37662

TP-LINK TL-7DR5130 v1.0.23 is vulnerable to TCP DoS or hijacking attacks. An attacker in the same WLAN as the victim can disconnect or hijack the traffic between the victim and any remote server by sending out forged TCP RST messages to evict NAT mappings in the router.

Weakness

The product establishes a communication channel to handle an incoming request that has been initiated by an actor, but it does not properly verify that the request is coming from the expected origin.

Potential Mitigations

• Use a mechanism that can validate the identity of the source, such as a certificate, and validate the integrity of data to ensure that it cannot be modified in transit using an Adversary-in-the-Middle (AITM) attack.
• When designing functionality of actions in the URL scheme, consider whether the action should be accessible to all mobile applications, or if an allowlist of applications to interface with is appropriate.
