Detailsinfo

A vulnerability has been found in phpMyAdmin up to 4.0.10.15/4.4.15.6/4.6.2 (Database Administration Software) and classified as very critical. Affected by this vulnerability is some unknown functionality of the component preg_replace Handler. The manipulation with an unknown input leads to a code injection vulnerability. The CWE definition for the vulnerability is CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

phpMyAdmin 4.0.x before 4.0.10.16, 4.4.x before 4.4.15.7, and 4.6.x before 4.6.3 does not properly choose delimiters to prevent use of the preg_replace e (aka eval) modifier, which might allow remote attackers to execute arbitrary PHP code via a crafted string, as demonstrated by the table search-and-replace implementation.

The weakness was presented 07/03/2016 with Cure53 (Website). The advisory is shared at phpmyadmin.net. This vulnerability is known as CVE-2016-5734 since 06/21/2016. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are unknown but a public exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 02/01/2025). MITRE ATT&CK project uses the attack technique T1059 for this issue.

It is possible to download the exploit at exploit-db.com. It is declared as highly functional. We expect the 0-day to have been worth approximately $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 91939 (FreeBSD : phpMyAdmin -- multiple vulnerabilities (e7028e1d-3f9b-11e6-81f9-6805ca0b3d42)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family FreeBSD Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 11677 (phpMyAdmin Multiple Security Vulnerabilities (PMASA-2016-27, PMASA-2016-23)).

Upgrading to version 4.0.10.16, 4.4.15.7 or 4.6.3 eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Exploit-DB (40185), Tenable (91939) and SecurityFocus (BID 91387†). See VDB-88563, VDB-88565, VDB-88569 and VDB-88571 for similar entries. If you want to get the best quality for vulnerability data then you always have to consider VulDB.
