CVE-2023-46502Network attack vector

File disclosure and SSRF via external entities

Published Oct 30, 2023 · Updated Sep 9, 2024

XXE injection in openCRX 5.2.2 allows remote attackers to read server files and trigger SSRF through crafted XML requests. WebDavMethod.getDocumentBuilder creates a namespace-aware DocumentBuilderFactory without disabling DOCTYPE declarations, external entities, or external DTD loading. The network-reachable parser accepts attacker-controlled XML without authentication or user interaction, enabling server-local file reads and server-originated requests.
