Detailsinfo

A vulnerability was found in phpMyAdmin up to 4.6.3/4.4.15.7/4.0.10.16 (Database Administration Software). It has been classified as critical. Affected is an unknown function of the component Cookie Handler. The manipulation with an unknown input leads to a cryptographic issue vulnerability. CWE is classifying the issue as CWE-310. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

An issue was discovered in cookie encryption in phpMyAdmin. The decryption of the username/password is vulnerable to a padding oracle attack. This can allow an attacker who has access to a user's browser cookie file to decrypt the username and password. Furthermore, the same initialization vector (IV) is used to hash the username and password stored in the phpMyAdmin cookie. If a user has the same password as their username, an attacker who examines the browser cookie can see that they are the same - but the attacker can not directly decode these values from the cookie as it is still hashed. All 4.6.x versions (prior to 4.6.4), 4.4.x versions (prior to 4.4.15.8), and 4.0.x versions (prior to 4.0.10.17) are affected.

The bug was discovered 12/10/2016. The weakness was presented 12/11/2016 by Emanuel Bronshtein (Website). The advisory is available at securityfocus.com. This vulnerability is traded as CVE-2016-6606 since 08/06/2016. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1600 by the MITRE ATT&CK project.
