CloudBees Security Advisory 2023-03-21

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.

OctoPerf Load Testing Plugin Plugin 4.5.1 requires POST requests for the affected connection test HTTP endpoint.

SECURITY-3067 (2) / CVE-2023-28672
Severity (CVSS): High
Affected plugin: octoperf
Description:

OctoPerf Load Testing Plugin Plugin 4.5.1 and earlier does not perform a permission check in a connection test HTTP endpoint.

This allows attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

OctoPerf Load Testing Plugin Plugin 4.5.2 properly performs a permission check when accessing the affected connection test HTTP endpoint.

SECURITY-3067 (3) / CVE-2023-28673
Severity (CVSS): Medium
Affected plugin: octoperf
Description:

OctoPerf Load Testing Plugin Plugin 4.5.2 and earlier does not perform a permission check in an HTTP endpoint.

This allows attackers with Overall/Read permission to enumerate credentials IDs of credentials stored in Jenkins. Those can be used as part of an attack to capture the credentials using another vulnerability.

An enumeration of credentials IDs in OctoPerf Load Testing Plugin Plugin 4.5.3 requires the appropriate permissions.

SECURITY-3067 (4) / CVE-2023-28674 (CSRF), CVE-2023-28675 (missing permission check)
Severity (CVSS): Medium
Affected plugin: octoperf
Description:

OctoPerf Load Testing Plugin Plugin 4.5.2 and earlier does not perform permission checks in several HTTP endpoints.

This allows attackers with Overall/Read permission to connect to a previously configured Octoperf server using attacker-specified credentials.

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

OctoPerf Load Testing Plugin Plugin 4.5.3 requires POST requests and the appropriate permissions for the affected HTTP endpoints.

SECURITY-2963 / CVE-2023-28676
Severity (CVSS): High
Affected plugin: convert-to-pipeline
Description:

Convert To Pipeline Plugin 1.0 and earlier does not require POST requests for the HTTP endpoint converting a Freestyle project to Pipeline, resulting in a cross-site request forgery (CSRF) vulnerability.

This vulnerability allows attackers to create a Pipeline based on a Freestyle project. Combined with SECURITY-2966, this can result in the execution of unsandboxed Pipeline scripts.

As of publication of this advisory, there is no fix.

SECURITY-2966 / CVE-2023-28677
Severity (CVSS): High
Affected plugin: convert-to-pipeline
Description:

Convert To Pipeline Plugin 1.0 and earlier uses basic string concatenation to convert Freestyle projects' Build Environment, Build Steps, and Post-build Actions to the equivalent Pipeline step invocations.

This allows attackers able to configure Freestyle projects to prepare a crafted configuration that injects Pipeline script code into the (unsandboxed) Pipeline resulting from a convertion by Convert To Pipeline Plugin. If an administrator converts the Freestyle project to a Pipeline, the script will be pre-approved.

As of publication of this advisory, there is no fix.

SECURITY-2809 / CVE-2023-28678
Severity (CVSS): High
Affected plugin: cppcheck
Description:

Cppcheck Plugin 1.26 and earlier does not escape file names from Cppcheck report files before showing them on the Jenkins UI.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to control report file contents.

As of publication of this advisory, there is no fix.

SECURITY-2813 / CVE-2023-28679
Severity (CVSS): High
Affected plugin: mashup-portlets-plugin
Description:

Mashup Portlets Plugin 1.1.2 and earlier provides the "Generic JS Portlet" feature that lets a user populate a portlet using a custom JavaScript expression.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by authenticated attackers with Overall/Read permission.

As of publication of this advisory, there is no fix.
