Octopus Deploy is an automated deployment and release management server. It is designed to simplify deployment of ASP.NET applications, Windows Services, and databases. Crafted requests to the deployment’s API endpoint can be used to force the deployment server to execute arbitrary scripts via a weaponized template. Valid credentials are required to perform the attack.
- The authenticated attacker makes a PUT request to the deployment’s API containing a weaponized call to detonate arbitrary script against the deployment server.
- The deployment server deploys the weaponized script resulting in payload execution.
The public-facing host running Octopus Deploy Server is configured with an available project.
Alert Logic Coverage
Alert Logic® has evaluated its customer base for exposure to the exploit and has developed signatures for mitigating the threat depending on the security service in place.
The Network-Based Intrusion Detection System (IDS) has been updated with the new signatures for this exploit when detected via Alert Logic Threat Manager™. If this signature is detected, an incident is generated in the Alert Logic console.
Recommendations for Mitigation
Restrict access to the vulnerable server to only those locations which are necessary. remove public access if it is not expressly required.
