Summary
Jenkins OpenShift Login Plugin vulnerable to Open Redirect
Jenkins OpenShift Login Plugin 1.1.0.227.v27e08dfb_1a_20 and earlier improperly determines that a redirect URL after login is legitimately pointing to Jenkins.
This allows attackers to perform phishing attacks by having users go to a Jenkins URL that will forward them to a different site after successful authentication.
OpenShift Login Plugin 1.1.0.230.v5d7030b_f5432 only redirects to relative (Jenkins) URLs.
Impact
Untrusted input controls a URL used for redirection, which can forward users to attacker-controlled sites. Typical impact: phishing and credential harvesting via a trusted domain.
CVE-2023-37947 has a CVSS score of 4.3 (Medium). The vector is network-reachable, no privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (1.1.0.230.v5d7030b); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2023-37947? CVE-2023-37947 is a medium-severity open redirect vulnerability in org.openshift.jenkins:openshift-login (maven), affecting versions < 1.1.0.230.v5d7030b. It is fixed in 1.1.0.230.v5d7030b. Untrusted input controls a URL used for redirection, which can forward users to attacker-controlled sites.
- How severe is CVE-2023-37947? CVE-2023-37947 has a CVSS score of 4.3 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of org.openshift.jenkins:openshift-login are affected by CVE-2023-37947? org.openshift.jenkins:openshift-login (maven) versions < 1.1.0.230.v5d7030b is affected.
- Is there a fix for CVE-2023-37947? Yes. CVE-2023-37947 is fixed in 1.1.0.230.v5d7030b. Upgrade to this version or later.
- Is CVE-2023-37947 exploitable, and should I be worried? Whether CVE-2023-37947 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2023-37947 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2023-37947? Upgrade
org.openshift.jenkins:openshift-loginto 1.1.0.230.v5d7030b or later.
