Title
Security advisory: Pre-authentication RCE in DataStax Enterprise (DSE) 6.8.49 (DataStax)
Summary
0day Rubbish Research Team is publicly disclosing a vulnerability in DataStax Enterprise (DSE) 6.8.49 (DataStax). The research is published and a proof-of-concept is available. Pre-authentication RCE (CVSS 9.8, pre-authentication) DataStax Enterprise (DSE) 6.8.49 runs a Gremlin Server on WebSocket 8182. The default configuration has the gremlin_server authentication section commented out, which means TinkerPop's default allowAll authenticator - no authentication. The gremlin-groovy sandbox is enabled by default, but the sandbox only wraps the top-level submitted script; groovy.lang.Script.evaluate(String) creates a fresh GroovyShell with a default CompilerConfiguration that does not include the SandboxTransformer, so a nested string is compiled and executed sandbox-free. An attacker submits this.evaluate("<nested script>"); the nested script runs ["/bin/sh","-c","<cmd>"].execute().text, executing arbitrary system commands as the dse user. Dynamically verified. Impact: Full read of the host filesystem and configuration as the dse user, arbitrary OS command execution, and full control of the DSE host and database services.
