📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker could achieve remote code execution with the privileges of the Octopus Deploy service account, potentially compromising the entire Octopus Server and connected infrastructure.
Likely Case
Authenticated users with package creation permissions could execute arbitrary commands on the Octopus Server, leading to data exfiltration, lateral movement, or service disruption.
If Mitigated
With proper access controls limiting package creation to trusted users only, the risk is reduced to authorized personnel who could still abuse their legitimate access.
🎯 Exploit Status
Exploitation requires authenticated access with package creation permissions. The vulnerability is in the offline package creation feature.
