Description

CSRF vulnerability in Jenkins Swarm Plugin

Swarm Plugin adds API endpoints to add or remove agent labels. In Swarm Plugin 3.20 and earlier these only require a global Swarm secret to use, and no regular permission check is performed. This allows users with Agent/Create permission to add or remove labels of any agent.

Additionally, these API endpoints do not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.

Swarm Plugin 3.21 requires POST requests and Agent/Configure permission for the affected agent to these endpoints. It no longer uses the global Swarm secret for these API endpoints.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity low, availability low.

Weakness class

CVE-2020-2192 is classified as CWE-352: Cross-Site Request Forgery (CSRF). A state-changing request is accepted without proof it was intended, so another site can trigger it using the victim's session.
