Patched versions

1.3

Description

Deployer Framework Plugin is a framework plugin allowing other plugins to provide a way to deploy artifacts. Deployer Framework Plugin 1.2 and earlier does not escape the URL displayed in the build home page. This results in a stored cross-site scripting (XSS) vulnerability exploitable by users able to provide the location.

The exploitability of this vulnerability depends on the specific implementation using Deployer Framework Plugin. The Jenkins security team is not aware of any exploitable implementation.

Deployer Framework Plugin 1.3 escapes the URL.

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.
