CVE-2020-9032Public exploitNetwork attack vector

Unauthenticated file access via kernlog.php path traversal

Published Feb 17, 2020 · Updated Aug 4, 2024

Path traversal in Symmetricom SyncServer devices allows remote attackers to access files through kernlog.php's FileName parameter. kernlog.php accepts attacker-controlled traversal paths in FileName without confining the resolved target to the intended log directory. The issue requires no authentication and affects S100 2.90.70.3, S200 1.30, S250 1.25, S300 2.65.0, and S350 2.80.1; public records do not identify which files are exposed.
