Affected packages
• Go github.com/fkie-cad/yapscan: >= 0.18.0, < 0.19.1 → fixed in 0.19.1
Description
Impact
If you make use of the report receiver server (experimental), a client may be able to forge requests such that arbitrary files on the host can be overwritten (subject to permissions of the yapscan server), leading to loss of data. This is particularly problematic if you do not authenticate clients and/or run the server with elevated permissions.
Patches
Vulnerable versions:
• v0.18.0
• v0.19.0 (unreleased)
This problem is patched in version v0.19.1
Workarounds
Update to the newer version is highly encouraged!
Measures to reduce the risk of this include authenticating clients (see `--client-ca` flag) and containerization of the yapscan server.
