Nsa: >> Emissary Security Vulnerabilities
Emissary is a P2P-based, data-driven workflow engine. Emissary version 6.4.0 is vulnerable to Server-Side Request Forgery (SSRF). In particular, the `RegisterPeerAction` endpoint and the `AddChildDirectoryAction` endpoint are vulnerable to SSRF. This vulnerability may lead to credential leaks. Emissary version 7.0 contains a patch. As a workaround, disable network access to Emissary from untrusted sources.

Emissary is a P2P based data-driven workflow engine. Affected versions of Emissary are vulnerable to post-authentication Remote Code Execution (RCE). The [`CreatePlace`](https://github.com/NationalSecurityAgency/emissary/blob/30c54ef16c6eb6ed09604a929939fb9f66868382/src/main/java/emissary/server/mvc/internal/CreatePlaceAction.java#L36) REST endpoint accepts an `sppClassName` parameter which is used to load an arbitrary class. This class is later instantiated using a constructor with the following signature: `<constructor>(String, String, String)`. An attacker may find a gadget (class) in the application classpath that could be used to achieve Remote Code Execution (RCE) or disrupt the application. Even though the chances to find a gadget (class) that allow arbitrary code execution are low, an attacker can still find gadgets that could potentially crash the application or leak sensitive data. As a work around disable network access to Emissary from untrusted sources.

Emissary is a distributed, peer-to-peer, data-driven workflow framework. Emissary 6.4.0 is vulnerable to Unsafe Deserialization of post-authenticated requests to the [`WorkSpaceClientEnqueue.action`](https://github.com/NationalSecurityAgency/emissary/blob/30c54ef16c6eb6ed09604a929939fb9f66868382/src/main/java/emissary/server/mvc/internal/WorkSpaceClientEnqueueAction.java) REST endpoint. This issue may lead to post-auth Remote Code Execution. This issue has been patched in version 6.5.0. As a workaround, one can disable network access to Emissary from untrusted sources.
