- Summary
- Smokescreen SSRF via deny list bypass (square brackets)
- Details
-
Impact
The primary use case for Smokescreen is to prevent server-side request forgery (SSRF) attacks in which external attackers leverage the behavior of applications to connect to or scan internal infrastructure.
Smokescreen also offers an option to deny access to additional (e.g., external) URLs by way of a deny list. There was an issue in Smokescreen that made it possible to bypass the deny list feature by surrounding the hostname with square brackets (e.g.
[example.com]).Recommendation
Upgrade Smokescreen to version 0.0.4 or later.
