CVE-2011-4107

phpMyAdmin vulnerable to XML external entity (XXE) injection attack

The simplexml_load_string function in the XML import plug-in (libraries/import/xml.php) in phpMyAdmin 3.4.x before 3.4.7.1 and 3.3.x before 3.3.10.5 allows remote authenticated users to read arbitrary files via XML data containing external entity references, aka an XML external entity (XXE) injection attack.

An XML parser processes external entity references in untrusted input, causing the server to fetch internal resources or remote URLs. Typical impact: local file disclosure, server-side request forgery, or denial of service.

CVE-2011-4107 has a CVSS score of 6.5 (Medium). The vector is network-reachable, low privileges required, and no user interaction. 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 (3.4.7.1, 3.3.10.5); upgrading removes the vulnerable code path.

1. What is CVE-2011-4107? CVE-2011-4107 is a medium-severity XML external entity injection (XXE) vulnerability in phpmyadmin/phpmyadmin (composer), affecting versions >= 3.4.0, < 3.4.7.1. It is fixed in 3.4.7.1, 3.3.10.5. An XML parser processes external entity references in untrusted input, causing the server to fetch internal resources or remote URLs.
2. How severe is CVE-2011-4107? CVE-2011-4107 has a CVSS score of 6.5 (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.
3. Which versions of phpmyadmin/phpmyadmin are affected by CVE-2011-4107? phpmyadmin/phpmyadmin (composer) versions >= 3.4.0, < 3.4.7.1 is affected.
4. Is there a fix for CVE-2011-4107? Yes. CVE-2011-4107 is fixed in 3.4.7.1, 3.3.10.5. Upgrade to this version or later.
5. Is CVE-2011-4107 exploitable, and should I be worried? Whether CVE-2011-4107 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-2011-4107 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-2011-4107?
   • Upgrade phpmyadmin/phpmyadmin to 3.4.7.1 or later
   • Upgrade phpmyadmin/phpmyadmin to 3.3.10.5 or later
