Technical Analysis

CVE-2022-2760 is a medium-severity information exposure vulnerability affecting Octopus Deploy's Octopus Server product. The vulnerability arises when an authenticated user with limited privileges attempts to access resources that belong to a different 'Space' within the Octopus Server environment. Instead of simply denying access, the server discloses the Space ID of the inaccessible space in an error message. This behavior constitutes an information leak classified under CWE-209 (Information Exposure Through an Error Message). The vulnerability affects multiple versions of Octopus Server, including 2019.5.7, 2022.2.6729, and 2022.3.348, among others. The CVSS v3.1 base score is 4.3 (medium), with the vector AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N, indicating that the vulnerability can be exploited remotely over the network with low attack complexity, requires low privileges (authenticated user), no user interaction, and results in limited confidentiality impact without affecting integrity or availability. No known exploits have been reported in the wild, and no official patches or mitigation links were provided in the source information. The core issue is that error messages reveal internal identifiers (Space IDs) that should remain confidential, potentially aiding an attacker in reconnaissance activities or targeted attacks by mapping the internal structure of the Octopus Deploy environment.

Potential Impact

For European organizations using Octopus Deploy Octopus Server, this vulnerability could lead to unauthorized disclosure of internal organizational structure details, specifically the Space IDs of deployment environments they do not have access to. While the direct impact on confidentiality is limited to these identifiers, such information can be leveraged by attackers to better understand the target environment, potentially facilitating more focused social engineering, privilege escalation attempts, or lateral movement within the network. Given that Octopus Deploy is widely used for automated deployment and DevOps workflows, exposure of Space IDs could indirectly aid attackers in crafting attacks against critical deployment pipelines or infrastructure. However, since the vulnerability requires authenticated access with at least low privileges, the risk is somewhat mitigated by existing access controls. The vulnerability does not affect integrity or availability, so it does not directly compromise system operations or data modification capabilities. Nonetheless, the information leak could be a stepping stone in a multi-stage attack targeting European enterprises relying on Octopus Deploy for their software delivery processes.

Mitigation Recommendations

To mitigate this vulnerability, European organizations should: 1) Upgrade Octopus Deploy Octopus Server to the latest version where this issue is addressed, or apply any vendor-provided patches as soon as they become available. 2) Review and tighten access controls to ensure that users have the minimum necessary privileges, reducing the risk that low-privileged users can exploit this information leak. 3) Implement monitoring and alerting on unusual access patterns or error messages that might indicate attempts to enumerate Spaces or probe the system. 4) Customize error handling and logging configurations to avoid leaking sensitive internal identifiers in error messages or logs accessible to users. 5) Conduct internal security assessments and penetration tests focusing on information disclosure vectors within deployment and DevOps tools. 6) Educate users about the risks of information disclosure and encourage reporting of suspicious system behavior. These steps go beyond generic advice by focusing on access control hygiene, error message management, and proactive detection tailored to the Octopus Deploy environment.
