Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceImproper Certificate Validation vulnerability in Micro Focus Application Automation Tools Jenkins plugin (versions 6.7 and earlier) allows unconditionally disabling SSL/TLS certificate validation. This means SSL/TLS certificate verification can be bypassed, enabling man-in-the-middle attacks and compromising encrypted communications.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Micro Focus Application Automation Tools plugin is installedIn Jenkins, go to Manage Jenkins > Manage Plugins > Installed and look for 'Micro Focus Application Automation Tools' in the list.
