Description

DotCi Plugin provides a webhook endpoint at /githook/ that can be used to trigger builds of the job for a GitHub repository.

In DotCi Plugin 2.40.00 and earlier, this endpoint can be accessed without authentication.

This allows unauthenticated attackers to trigger builds of jobs corresponding to the attacker-specified repository for attacker-specified commits.

This plugin has been suspended.

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.
