CWE-1088: Synchronous Access of Remote Resource without Timeout
The code has a synchronous call to a remote resource, but there is no timeout for the call, or the timeout is set to infinite.
How it's found
Synchronous Access of Remote Resource without Timeout 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.
Consequences
- Reduce Reliability: This issue can prevent the product from running reliably, since an outage for the remote resource can cause the product to hang. If the relevant code is reachable by an attacker, then this reliability problem might introduce a vulnerability.
Where this fits in a TurboPentest engagement
This weakness is not covered by the automated black-box pentest. IntegSec pentesters cover it in a manual engagement.
