CVE-2020-25561Public exploit

Credential exposure via client configuration storage

Published Aug 11, 2021 · Updated Aug 4, 2024

Credential exposure in SapphireIMS 5 allows local users to obtain reusable client-to-server credentials from ServerConf.config. The client stores the fixed sapphire:ims credential in that file and reuses it to authenticate to the server. Local low-privileged access to the client is required; the disclosure establishes credential exposure but does not define the account's server privileges.
