Multiple vulnerabilities have been discovered in phpMyAdmin, the most severe of which could result in remote code execution. These vulnerabilities can be exploited if an attacker crafts and sends a malicious request to the affected application. Details of the vulnerabilities are as follows:
· A remote code execution vulnerability exists in the phpMyAdmin unserialize() function (CVE-2016-6620).
· A elevation of privilege vulnerability exists when the phpMyAdmin function PMA_safeUnserialize() function is manipulated with an unknown input (CVE-2016-9865)
Successful exploitation of these vulnerabilities could result in an attacker gaining the same privileges as the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
We recommend the following actions be taken:
· Upgrade to the latest version of PHP immediately, after appropriate testing.
· Verify no unauthorized system modifications have occurred on system before applying patch.
· Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
· Apply the principle of Least Privilege to all systems and services.
