Security readout for executives and security teams
Plain-English summary
This issue affects older Cloud Foundry UAA password reset handling. Because multiple reset codes could remain valid at once, an attacker could have a better chance of guessing a valid code and taking over an internal-user account. It matters only where UAA’s internal user store is used.
Executive priority
Prioritize remediation if legacy Cloud Foundry authentication still uses UAA’s internal user store. Risk is narrower than internet-wide exploitation, but the business impact could include account takeover for affected users.
Technical view
CVE-2016-3084 is a brute-force weakness in the UAA reset password flow caused by multiple active codes existing at the same time. Affected products include Cloud Foundry release v236 and earlier, UAA v3.3.0 and earlier, UAA v10 and earlier, all Login-server versions, and Pivotal Elastic Runtime before 1.7.2.
Likely exposure
Exposure is limited to Cloud Foundry or Pivotal Elastic Runtime deployments using the UAA internal user store. Deployments using SAML or LDAP integration for authentication are stated as not affected.
Exploitation context
The provided sources do not report active exploitation, and the CVE is not listed as KEV. The source bundle also does not provide CVSS scoring or public exploit evidence.
Researcher notes
The key exposure condition is authentication source, not just product presence. The public data lacks CVSS, CWE, detailed fixed-version mapping beyond affected ranges, and exploitation confirmation. Avoid assuming SAML or LDAP deployments are vulnerable based only on product version.
Mitigation direction
- Identify whether UAA internal user store authentication is enabled.
- Upgrade affected Cloud Foundry, UAA, Login-server, or Elastic Runtime versions per vendor guidance.
- Prefer SAML or LDAP integration where operationally appropriate.
- Review vendor advisory details before changing authentication architecture.
Validation and detection
- Inventory Cloud Foundry, UAA, Login-server, and Elastic Runtime versions.
- Confirm whether users authenticate through UAA internal store, SAML, or LDAP.
- Review password reset configuration and reset-code handling in affected UAA deployments.
- Check logs for unusual password reset volume or repeated failures.

Conservative CVE-to-ATT&CK context
These mappings and lookup hints may be relevant to the vulnerability behavior, CWE, affected product, or exposure path. Glexia-inferred context is not an official MITRE, ATT&CK, CWE, or CVE Program mapping.
ATT&CK lookup starting points
Use these exact CWE pages and searches to review the Glexia ATT&CK library from this CVE's weakness and description context.
Credential and access behavior lookup
The CVE wording references authentication or credential exposure, so valid-account and credential-access review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
