CVE-2024-51135Public exploitNetwork attack vector

Data disclosure and code execution via XXE

Published Nov 11, 2024 · Updated Nov 12, 2024

XXE in Power TAC Simulation Server 1.9.0 allows remote attackers to read sensitive data or execute code through crafted XML. BootstrapDataRepo.readBootRecord creates a DocumentBuilderFactory that permits DOCTYPE declarations and external entities while parsing bootstrap data from an attacker-controlled URL or file. Reachability requires control of the bootstrap XML source; entity resolution can trigger server-side requests, disclose local data, or execute code in the server context.
