Security readout for executives and security teams
Plain-English summary
CVE-2018-11041 is an open redirect issue in Cloud Foundry UAA. A malicious link could send a user to an attacker-chosen website after the user successfully logs in. This mainly creates phishing and trust-abuse risk around authentication, not direct code execution based on the provided sources.
Executive priority
Treat this as a moderate authentication-trust issue. It is not reported as actively exploited in the provided sources, but public login portals should be remediated promptly because the flaw can strengthen phishing campaigns.
Technical view
Cloud Foundry UAA failed to validate redirect URL values in a form parameter used for internal redirects on the login page. A remote attacker could craft a link that redirects authenticated users to arbitrary websites after successful login. Affected ranges are UAA later than 4.6.0 before 4.19.0, with stated exceptions, and uaa-release later than v48 before v60, with stated exceptions.
Likely exposure
Exposure is most likely where Cloud Foundry UAA login pages are reachable by users and run affected versions. Public or partner-facing authentication portals carry higher phishing risk than tightly internal deployments.
Exploitation context
The bundle does not show CISA KEV listing or active exploitation evidence. Exploitation requires a crafted link and user interaction, followed by successful login, then redirection to an arbitrary website.
Researcher notes
The source bundle lacks CVSS, CWE, and exploit-status detail. Analysis should stay bounded to open redirect behavior, affected version ranges, and user-assisted exploitation after successful login. Do not infer broader authentication bypass or token theft without additional evidence.
Mitigation direction
- Inventory Cloud Foundry UAA and uaa-release versions in all foundations.
- Upgrade to versions outside the affected ranges identified by Cloud Foundry.
- Prioritize public or broadly accessible UAA login endpoints first.
- Review Cloud Foundry advisory guidance before applying compensating controls.
- Monitor authentication-related phishing reports and unusual post-login redirects.
Validation and detection
- Confirm each UAA deployment version against the affected and excepted version ranges.
- Identify whether UAA login endpoints are internet, partner, or internal facing.
- Test in a controlled environment that post-login redirects stay within expected destinations.
- Review access logs for unusual login flows followed by external redirects.
- Document remediation status for each Cloud Foundry foundation.
