Jenkins Gogs Plugin vulnerable to unsafe default behavior and information disclosure

Moderate severity GitHub Reviewed Published Aug 16, 2023 to the GitHub Advisory Database • Updated Oct 9, 2024

Package

maven org.jenkins-ci.plugins:gogs-webhook (Maven)

Affected versions

<= 1.0.15

Patched versions

None

Description

Jenkins Gogs Plugin provides a webhook endpoint at /gogs-webhook that can be used to trigger builds of jobs. In Gogs Plugin 1.0.15 and earlier, an option to specify a Gogs secret for this webhook is provided, but not enabled by default.

This allows unauthenticated attackers to trigger builds of jobs corresponding to the attacker-specified job name.

Additionally, the output of the webhook endpoint includes whether a job corresponding to the attacker-specified job name exists, even if the attacker has no permission to access it.

As of publication of this advisory, there is no fix.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
