CVE-2016-3167

Open redirect vulnerability in the drupal_goto function in Drupal 6.x before 6.38, when used with PHP before 5.4.7, allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a double-encoded URL in the "destination" parameter.

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-2016-3167 has a CVSS score of 7.4 (High). 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 (6.38); upgrading removes the vulnerable code path.

1. What is CVE-2016-3167? CVE-2016-3167 is a high-severity open redirect vulnerability in drupal/core (composer), affecting versions >= 6.0, < 6.38. It is fixed in 6.38. Untrusted input controls a URL used for redirection, which can forward users to attacker-controlled sites.
2. How severe is CVE-2016-3167? CVE-2016-3167 has a CVSS score of 7.4 (High). 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.
3. Which packages are affected by CVE-2016-3167?
   • drupal/core (composer) (versions >= 6.0, < 6.38)
   • drupal/drupal (composer) (versions >= 6.0, < 6.38)
4. Is there a fix for CVE-2016-3167? Yes. CVE-2016-3167 is fixed in 6.38. Upgrade to this version or later.
5. Is CVE-2016-3167 exploitable, and should I be worried? Whether CVE-2016-3167 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.

6. What actually determines whether CVE-2016-3167 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.
7. How do I fix CVE-2016-3167?
   • Upgrade drupal/core to 6.38 or later
   • Upgrade drupal/drupal to 6.38 or later
