CVE-2024-0882Public exploitNetwork attack vector

Arbitrary file read via unfiltered download path

Published Jan 25, 2024 · Updated Sep 5, 2024

Path traversal in LinkWeChat 5.1.0 allows remote authenticated users to read server files accessible to the download service. The /linkwechat-api/common/download/resource endpoint accepts a name parameter without filtering ../ directory-jump sequences before resolving the requested path. A valid session is required; the demonstrated request discloses /etc/passwd without modifying or interrupting the service.
