PoC-Gym: Towards More Reliable LLM-Assisted Proof-of-Concept Exploit Generation

Amartya Das, Claire Wang, Derin Gezgin, Nevena Stojkovic, Shinhae Kim, Zhengdong Huang

PoC-Gym generates post-hoc valid PoCs for 12 of 20 Java CVEs by requiring candidates to reach ground-truth vulnerable locations.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Across 338 runs on 20 Java CVEs, PoC-Gym produces 65 post-hoc valid PoCs covering 12 CVEs; on the 14-CVE overlap with FaultLine the strongest configuration succeeds on 8 CVEs versus FaultLine's 5.

C2weakest assumption

That reaching the ground-truth vulnerable location after a runtime-valid execution is sufficient evidence that the PoC actually triggers the reported vulnerability rather than an unrelated path.

C3one line summary

PoC-Gym generates PoC exploits for Java CVEs via iterative LLM prompting with static traces and coverage feedback, yielding post-hoc valid PoCs for 12 of 20 evaluated CVEs and outperforming FaultLine on the 14-CVE overlap.
