CWE-924: Improper Enforcement of Message Integrity During Transmission in a Communication Channel
The product establishes a communication channel with an endpoint and receives a message from that endpoint, but it does not sufficiently ensure that the message was not modified during transmission.
How it's found
Improper Enforcement of Message Integrity During Transmission in a Communication Channel is typically found by tracing untrusted input from where it enters the system to the point where it is used without the check or neutralization this weakness describes, combining manual code review with dynamic testing.
Attackers might be able to modify the message and spoof the endpoint by interfering with the data as it crosses the network or by redirecting the connection to a system under their control.
Consequences
- Gain Privileges or Assume Identity: If an attackers can spoof the endpoint, the attacker gains all the privileges that were intended for the original endpoint.
Where this fits in a TurboPentest engagement
TurboPentest's agentic pentest is powerful and covers a broad range of issues automatically. This particular class is best confirmed in a manual IntegSec engagement, where human pentesters apply deeper methodology and a larger context window than any automated pass.
