Summary
AxxonSoft's Axxon One video surveillance and security management software, on both Windows and Linux, is affected. A remote user with limited privileges can exploit a flaw in its security configuration API to view the full list of user accounts and roles, which could help them plan further attacks against the system.
Read the original description
Exposure of Sensitive Information to an Unauthorized Actor (CWE-200) in the security configuration API in AxxonSoft Axxon One before 3.2.0 on Windows and Linux allows a remote authenticated user with limited privileges to enumerate all user accounts and roles configured in the system via the user configuration request, which returned the complete lists of users and roles regardless of the caller's permissions.
What to do
Upgrade to a fixed version: 3.2.0.
