Vulnerability from osv_ubuntu

Published

2021-04-27 06:15

Modified

2026-04-22 07:39

Summary

Details

Unbound before 1.9.5 allows configuration injection in create_unbound_ad_servers.sh upon a successful man-in-the-middle attack against a cleartext HTTP session. NOTE: The vendor does not consider this a vulnerability of the Unbound software. create_unbound_ad_servers.sh is a contributed script from the community that facilitates automatic configuration creation. It is not part of the Unbound installation

Severity

5.9 (Medium)
