- Fix
1.600- Upgrade org.jenkins-ci.main:jenkins-core to this version or later
Description
The HudsonPrivateSecurityRealm class in Jenkins before 1.600 and LTS before 1.596.1 does not restrict access to reserved names when using the "Jenkins' own user database" setting, which allows remote attackers to gain privileges by creating a reserved name.
Affected versions
Maven
| Package | Vulnerable | Fixed in |
|---|---|---|
| org.jenkins-ci.main:jenkins-core | >= 1.597, < 1.600 |
1.600 |
| org.jenkins-ci.main:jenkins-core | < 1.596.1 |
1.596.1 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness
CWE-287: Improper Authentication

How to prevent it
- Architecture and Design: Use an authentication framework or library such as the OWASP ESAPI Authentication feature.
