Upgrade phpmyadmin/phpmyadmin to 4.0.10.13
phpmyadmin/phpmyadmin fixed: 4.4.15.3 
Upgrade phpmyadmin/phpmyadmin to 4.4.15.3
phpmyadmin/phpmyadmin fixed: 4.5.4 
Upgrade phpmyadmin/phpmyadmin to 4.5.4
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for phpmyadmin/phpmyadmin

How to Check if You Are Affected

To determine whether your application is affected by CVE-2016-1927, inspect your project dependencies for Phpmyadmin/phpmyadmin:

inspect dependencies for phpmyadmin/phpmyadmin

Analyze the terminal output to locate any version of Phpmyadmin/phpmyadmin in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.0.10.13), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Phpmyadmin/phpmyadmin, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The `suggestPassword` function in `js/functions.js` in phpMyAdmin 4.0.x before 4.0.10.13, 4.4.x before 4.4.15.3, and 4.5.x before 4.5.4 relies on the `Math.random` JavaScript function, which makes it easier for remote attackers to guess passwords via a brute-force approach.
