This vulnerability allows attackers to connect to an attacker-specified URL, capturing GitHub credentials associated with an attacker-specified job.

This issue is due to an incomplete fix of SECURITY-2502.

Blue Ocean Plugin 1.27.5.1 uses the configured SCM URL, instead of a user-specified URL provided as a parameter to the HTTP endpoint.

CSRF vulnerability and missing permission checks in Fortify Plugin allow capturing credentials

SECURITY-3115 / CVE-2023-4301 (CSRF), CVE-2023-4302 (missing permission check)

Severity (CVSS): [pill:Medium|https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N]

Affected plugin: [pill:fortify|https://plugins.jenkins.io/fortify]

Description:

Fortify Plugin 22.1.38 and earlier does not perform permission checks in several HTTP endpoints.

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.

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

Fortify Plugin 22.2.39 requires POST requests and the appropriate permissions for the affected HTTP endpoints.

HTML injection vulnerability in Fortify Plugin

SECURITY-3140 / CVE-2023-4303

Affected plugin: [pill:fortify|https://plugins.jenkins.io/fortify]

Description:

Fortify Plugin 22.1.38 and earlier does not escape the error message for a form validation method. This results in an HTML injection vulnerability.

Since Jenkins 2.275 and LTS 2.263.2, a security hardening for form validation responses prevents JavaScript execution, so no scripts can be injected.

Fortify Plugin 22.2.39 removes HTML tags from the error message.

Stored XSS vulnerability in Flaky Test Handler Plugin

SECURITY-3223 / CVE-2023-40342

Severity (CVSS): [pill:High|https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H]

Affected plugin: [pill:flaky-test-handler|https://plugins.jenkins.io/flaky-test-handler]

Description:

Flaky Test Handler Plugin 1.2.2 and earlier does not escape JUnit test contents when showing them on the Jenkins UI.

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

Flaky Test Handler Plugin 1.2.3 escapes JUnit test contents when showing them on the Jenkins UI.

Non-constant time token comparison in Tuleap Authentication Plugin

SECURITY-3229 / CVE-2023-40343

Affected plugin: [pill:tuleap-oauth|https://plugins.jenkins.io/tuleap-oauth]

Description:

Tuleap Authentication Plugin 1.1.20 and earlier does not use a constant-time comparison when checking whether two authentication tokens are equal.

This could potentially allow attackers to use statistical methods to obtain a valid authentication token.

Tuleap Authentication Plugin 1.1.21 uses a constant-time comparison when validating authentication tokens.

Missing permission check in Delphix Plugin allows enumerating credentials IDs

SECURITY-3214 (1) / CVE-2023-40344

Severity (CVSS): [pill:Medium|https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N]

Affected plugin: [pill:delphix|https://plugins.jenkins.io/delphix]

Description:

Delphix Plugin 3.0.2 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 Delphix Plugin 3.0.3 requires the appropriate permissions.

Exposure of system-scoped credentials in Delphix Plugin

SECURITY-3214 (2) / CVE-2023-40345

Severity (CVSS): [pill:Medium|https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N]

Affected plugin: [pill:delphix|https://plugins.jenkins.io/delphix]

Description:
