Description
A flaw was found in assisted-migration-agent. An unauthenticated attacker, located on the same local area network (LAN), can exploit a path traversal vulnerability. By crafting a specially designed gzipped tarball, the attacker can bypass security checks and write arbitrary files to the system. This could ultimately lead to the execution of unauthorized code on the appliance.
CWEs
- CWE-22 · Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
- CWE-59 · Improper Link Resolution Before File Access ('Link Following')
