CVE-2020-9030Public exploitNetwork attack vector

Unauthenticated file disclosure via syslog.php path traversal

Published Feb 17, 2020 · Updated Aug 4, 2024

Path traversal in SyncServer S100 2.90.70.3, S200 1.30, S250 1.25, S300 2.65.0, and S350 2.80.1 allows remote attackers to read files. The syslog.php endpoint fails to sanitize traversal sequences in the FileName parameter before retrieving the requested file. No authentication or user interaction is required; public evidence establishes disclosure of files accessible to the web service but not file modification.
