Summary
An authenticated command path traversal vulnerability in the management interface allows an authenticated administrator to read-protected system files.
Impact
Authenticated web GUI administrator can force the system to copy system files to the wrong location allowing him to read the contents. However, as by design web GUI administrators are allowed to use ssh keys to gain full console access, this finding has a low impact on our customers.
Affected Products
Guardian, CMC <v20.0.7.4 or <v19.0.12
Workarounds and Mitigations
Use internal firewall feature to limit management interface access and review user roles.
