Official description
A high-privileged remote attacker can upload malicious ZIP archive containing directory traversal sequences such as ../ can escape the intended extraction directory and write files to arbitrary locations on the server, potentially achieve arbitrary code execution due to improper validation of archive entry paths before writing files to disk which could result in full system compromise.

The underlying weakness: Path Traversal: '../filedir'
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize../ sequences that can resolve to a location that is outside of that directory.
How developers prevent this class of flaw
- Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: total).
- Record last changed materially (score, affected products, status or references).
