Yamcs Vulnerable to Authenticated Remote Code Execution (RCE) via Jython Algorithm Code Injection

Summary A Server-Side Code Injection vulnerability exists in the Yamcs script evaluation engine for Python algorithms. The application dynamically compiles and evaluates user-controlled algorithm text using Jython via the JSR-223 ScriptEngine API without enforcing a secure sandbox. An authenticat...

Arbitrary Code Injection

Overview Affected versions of this package are vulnerable to Arbitrary Code Injection via the dynamic evaluation of user-supplied algorithm code in the script evaluation engine. An attacker can execute arbitrary operating system commands by injecting malicious Jython code through the REST API whe...
