Octopus Octopus Server 3.4.0

In affected Microsoft Windows versions of Octopus Deploy, the server can be coerced into sending server-side requests that contain authentication material allowing a suitably positioned attacker to compromise the account running Octopus Server and potentially the host infrastructure itself.

In affected versions of Octopus Deploy where customers are using Active Directory for authentication it was possible for an unauthenticated user to make an API request against two endpoints which would retrieve some data from the associated Active Directory. The requests when crafted correctly would return specific information from user profiles (Email address/UPN and Display name) from one endpoint and group information ( Group ID and Display name) from the other. This vulnerability does not expose data within the Octopus Server product itself.

In affected versions of Octopus Server it was possible for a user with sufficient access to set custom headers in all server responses. By submitting a specifically crafted referrer header the user could ensure that all subsequent server responses would return 500 errors rendering the site mostly unusable. The user would be able to subsequently set and unset the referrer header to control the denial of service state with a valid CSRF token whilst new CSRF tokens could not be generated.

In affected versions of Octopus Deploy it was possible to upload files to unexpected locations on the host using an API endpoint. The field lacked validation which could potentially result in ways to circumvent expected workflows.

In affected versions of Octopus Server the preview import feature could be leveraged to identify the existence of a target file. This could provide an adversary with information that may aid in further attacks against the server.

In affected versions of Octopus Server error messages were handled unsafely on the error page. If an adversary could control any part of the error message they could embed code which may impact the user viewing the error message.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Linux and Microsoft Windows Octopus Server on Windows, Linux allows SQL Injection.This issue affects Octopus Server: from 2024.1.0 before 2024.1.13038, from 2024.2.0 before 2024.2.9482, from 2024.3.0 before 2024.3.12766.

Affected versions of Octopus Server had a weak content security policy.

In affected versions of Octopus Server OIDC cookies were using the wrong expiration time which could result in them using the maximum lifespan.

In affected versions of Octopus Server under certain circumstances it is possible for sensitive variables to be printed in the task log in clear-text.

In affected versions of Octopus Server under certain conditions, a user with specific role assignments can access restricted project artifacts.

In affected versions of Octopus Server with certain access levels it was possible to embed a Cross-Site Scripting payload on the audit page.

It was identified that in certain versions of Octopus Server, that a user created with no permissions could view all users, user roles and permissions. This functionality was removed in versions of Octopus Server after the fixed versions listed.

It is possible for an API key to be logged in clear text in the audit log file after an invalid login attempt.

A race condition was identified through which privilege escalation was possible in certain configurations.

In affected versions of Octopus Server it is possible for the OpenID client secret to be logged in clear text during the configuration of Octopus Server.

In affected versions of Octopus Deploy it is possible for a low privileged guest user to craft a request that allows enumeration/recon of an environment.

In affected versions of Octopus Deploy it is possible for a low privileged guest user to interact with extension endpoints.

In affected versions of Octopus Deploy it is possible to discover network details via error message
