We have identified and fixed a vulnerability in FishEye which allowed unauthenticated users to commit actions on behalf of any other authorised user. In order to exploit this vulnerability, an attacker requires access to your FishEye web interface.
FishEye server is only vulnerable if it has been configured to be a part of an Application link with Trusted Applications authentication. Unless you chose OAuth authentication when configuring previously created links, Trusted Applications was used by default.
If you are unable to upgrade your FishEye server you can do the following as a temporary workaround:
- Block access to your FishEye server web interface from untrusted networks, such as the Internet.
- Remove any Application links that use Trusted Applications authentication and re-create them using OAuth.
