This advisory announces vulnerabilities in the following Jenkins deliverables:
Jenkins 2.286 and earlier, LTS 2.277.1 and earlier does not validate the type of object created after loading the data submitted to the
config.xml REST API endpoint of a node.
This allows attackers with Computer/Configure permission to replace a node with one of a different type.
Jenkins 2.287, LTS 2.277.2 validates the type of object created and rejects objects of unexpected types.
Jenkins 2.286 and earlier, LTS 2.277.1 and earlier does not properly check that a newly created view has an allowed name. When a form to create a view is submitted, the name is included twice in the submission. One instance is validated, but the other instance is used to create the value.
This allows attackers with View/Create permission to create views with invalid or already-used names.
Jenkins 2.287, LTS 2.277.2 uses the same submitted value for validation and view creation.
promoted builds Plugin 3.9 and earlier does not require POST requests for HTTP endpoints implementing promotion (regular, forced, and re-execute), resulting in cross-site request forgery (CSRF) vulnerabilities.
These vulnerabilities allow attackers to promote builds.
promoted builds Plugin 3.9.1 requires POST requests for the affected HTTP endpoints.
|A security hardening since Jenkins 2.287 and LTS 2.277.2 prevents exploitation of this vulnerability.|
Micro Focus Application Automation Tools Plugin 6.7 and earlier does not perform permission checks in methods implementing form validation.
This allows attackers with Overall/Read permission to connect to attacker-specified URLs using attacker-specified username and password.
Additionally, these form validation methods do not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.
Micro Focus Application Automation Tools Plugin 6.8 requires POST requests and Overall/Administer permission for the affected form validation methods.
Micro Focus Application Automation Tools Plugin 6.7 and earlier does not escape user input in a form validation response.
This results in a reflected cross-site scripting (XSS) vulnerability.
Micro Focus Application Automation Tools Plugin 6.8 escapes user input in the affected form validation response.
|A security hardening since Jenkins 2.275 and LTS 2.263.2 prevents exploitation of this vulnerability.|
Micro Focus Application Automation Tools Plugin 6.7 and earlier unconditionally disables SSL/TLS certificate validation for connections to Service Virtualization servers.
Micro Focus Application Automation Tools Plugin 6.8 no longer disables SSL/TLS certificate validation unconditionally by default. It provides an option to disable SSL/TLS certification validation for connections to Service Virtualization servers.
These versions include fixes to the vulnerabilities described above. All prior versions are considered to be affected by these vulnerabilities unless otherwise indicated.
The Jenkins project would like to thank the reporters for discovering and reporting these vulnerabilities:
