CVE-2020-7222Public exploitNetwork attack vector

Unauthenticated read-only access via client-side result tampering

Published Jan 17, 2020 · Updated Aug 4, 2024

Improper authentication in Amcrest Web Server 2.520.AC00.18.R allows remote attackers to view all interface options without credentials. The login page places its authentication decision in returned JavaScript, and the interface trusts the client-modifiable result parameter as true. Network access to the web interface is sufficient; the bypass permits viewing every option but provides no reported ability to modify them.
