EPSS

• CVE-2014-3603: 0.84% estimated exploitation activity in the next 30 days; percentile 58.02 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

The (1) HttpResource and (2) FileBackedHttpResource implementations in Shibboleth Identity Provider (IdP) before 2.4.1 and OpenSAML Java 2.6.2 do not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

# Patch Next advisory brief: CVE-2014-3603

Advisory: Improper Validation of Certificate with Host Mismatch in Shibboleth Identity Provider and OpenSAML Java
IDs: CVE-2014-3603, GHSA-rm7v-gqfg-p2wc
Record: https://patchnext.com/advisories/cve-2014-3603 (revision 1, source checked 26 Oct 2026, 15:53 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: edu.internet2.middleware:shibboleth-identityprovider 2.4.1; org.opensaml:opensaml 2.6.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven edu.internet2.middleware:shibboleth-identityprovider: affected < 2.4.1; fixed in 2.4.1
- Maven org.opensaml:opensaml: affected < 2.6.2; fixed in 2.6.2

## Suggested inspection (read-only)
- Maven edu.internet2.middleware:shibboleth-identityprovider: check the installed version with your package manager.
- Maven org.opensaml:opensaml: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on edu.internet2.middleware:shibboleth-identityprovider, org.opensaml:opensaml.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-rm7v-gqfg-p2wc (GitHub-reviewed advisory GHSA-rm7v-gqfg-p2wc lists affected ranges: Maven edu.internet2.middleware:shibboleth-identityprovider >=0 =0 <2.6.2)
