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.

representing the current view's URL in inline JavaScript.
This results in a stored cross-site scripting (XSS) vulnerability exploitable
by authenticated attackers with Overall/Read permission.
Pipeline Aggregator View Plugin 1.14 obtains the current URL in a way not
susceptible to XSS.
CSRF vulnerability in OctoPerf Load Testing Plugin Plugin
SECURITY-3067 (1) / CVE-2023-28671
Severity (CVSS): Medium
Affected plugin: octoperf
Description:
OctoPerf Load Testing Plugin Plugin 4.5.0 and earlier does not require POST
requests for a connection test HTTP endpoint, resulting in a cross-site request
forgery (CSRF) vulnerability.
This vulnerability allows attackers 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 4.5.1 requires POST requests for the
affected connection test HTTP endpoint.
Missing permission check in OctoPerf Load Testing Plugin Plugin
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.
Missing permission check in OctoPerf Load Testing Plugin Plugin allows
enumerating credentials IDs
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.
CSRF vulnerability and missing permission checks in OctoPerf Load Testing
Plugin Plugin
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.
CSRF vulnerability in Convert To Pipeline Plugin results in RCE
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. Learn why we announce
this.
Command injection vulnerability in Convert To Pipeline Plugin results in RCE
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 conversion 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. Learn why we announce
this.
Stored XSS vulnerability in Cppcheck Plugin
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.
