**Descriptions****Incorrect permission checks in Role-based Authorization Strategy Plugin**

**SECURITY-3053 / CVE-2023-28668**  
**Severity (CVSS):** Medium  
**Affected plugin: role-strategy**  
**Description:**

Permissions in Jenkins can be enabled and disabled. Some permissions are disabled by default, e.g., Overall/Manage or Item/Extended Read. Disabled permissions cannot be granted directly, only through greater permissions that imply them (e.g., Overall/Administer or Item/Configure).

Role-based Authorization Strategy Plugin 587.v2872c41fa\_e51 and earlier grants permissions even after they’ve been disabled.

This allows attackers to have greater access than they’re entitled to after the following operations took place:

1.  A permission is granted to attackers directly or through groups.
    
2.  The permission is disabled, e.g., through the script console.
    

Role-based Authorization Strategy Plugin 587.588.v850a\_20a\_30162 does not grant disabled permissions.

According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
