Title
Security advisory: Pre-authentication RCE in Ontotext GraphDB 11.4.3 Free edition (Ontotext / Graphwise)
Summary
0day Rubbish Research Team is publicly disclosing a vulnerability in Ontotext GraphDB 11.4.3 Free edition (Ontotext / Graphwise). The research is published and a proof-of-concept is available. Pre-authentication RCE (CVSS 9.8, pre-authentication) Ontotext GraphDB 11.4.3 Free edition defaults to security=false, which bypasses the entire Spring Security filter chain. As a result, /rest/repositories/ruleset/upload and /repositories/* are anonymously reachable. A .pie ruleset upload is compiled at runtime by the system javac and loaded into the server process. RuleCompilerBase.compilePrefices inlines the namespace prefix verbatim into the generated Java source with only .trim() and no validation. An attacker injects Java code in the prefix; creating a graphdb:Sail repository triggers infer.initialize(), which executes the injected Runtime.exec as the GraphDB process user (root). No authentication and no license are required. Dynamically verified with uid=0(root). Impact: Full host compromise as root (the GraphDB process user); the attacker can read any file, execute arbitrary commands, and take full control of the GraphDB host and its repositories.
