CVE-2023-24815Public exploitNetwork attack vector

Classpath resource disclosure via unsanitized wildcard paths

Published Feb 9, 2023 · Updated Mar 10, 2025

Path traversal in Eclipse Foundation Vert.x Web 4.0.0 through 4.3.7 allows remote attackers to read classpath resources. Utils.pathOffset passes the wildcard route segment into resource lookup without converting Windows backslashes or removing dot segments. The application must use a Windows file system and expose StaticHandler on a wildcard route; access is limited to classpath resources.
