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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
