Package : phpmyadmin Version : 22.214.171.124-2+deb7u6 CVE ID : CVE-2016-6606 CVE-2016-6607 CVE-2016-6609 CVE-2016-6611 CVE-2016-6612 CVE-2016-6613 CVE-2016-6614 CVE-2016-6620 CVE-2016-6622 CVE-2016-6623 CVE-2016-6624 CVE-2016-6630 CVE-2016-6631
Phpmyadmin, a web administration tool for MySQL, had several vulnerabilities reported.
A pair of vulnerabilities were found affecting the way cookies are stored. The decryption of the username/password is vulnerable to a padding oracle attack. The can allow an attacker who has access to a user's browser cookie file to decrypt the username and password. A vulnerability was found where the same initialization vector 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.
Cross site scripting vulnerability in the replication feature
A specially crafted database name could be used to run arbitrary PHP commands through the array export feature.
A specially crafted database and/or table name can be used to trigger an SQL injection attack through the SQL export functionality.
A user can exploit the LOAD LOCAL INFILE functionality to expose files on the server to the database system.
A user can specially craft a symlink on disk, to a file which phpMyAdmin is permitted to read but the user is not, which phpMyAdmin will then expose to the user.
A vulnerability was reported with the %u username replacement functionality of the SaveDir and UploadDir features. When the username substitution is configured, a specially-crafted user name can be used to circumvent restrictions to traverse the file system.
A vulnerability was reported where some data is passed to the PHP unserialize() function without verification that it's valid serialized data. Due to how the PHP function operates, unserialization can result in code being loaded and executed due to object instantiation and autoloading, and a malicious user may be able to exploit this. Therefore, a malicious user may be able to manipulate the stored data in a way to exploit this weakness.
An unauthenticated user is able to execute a denial-of-service attack by forcing persistent connections when phpMyAdmin is running with $cfg['AllowArbitraryServer']=true;.
A malicious authorized user can cause a denial-of-service attack on a server by passing large values to a loop.
A vulnerability was discovered where, under certain circumstances, it may be possible to circumvent the phpMyAdmin IP-based authentication rules. When phpMyAdmin is used with IPv6 in a proxy server environment, and the proxy server is in the allowed range but the attacking computer is not allowed, this vulnerability can allow the attacking computer to connect despite the IP rules.
An authenticated user can trigger a denial-of-service attack by entering a very long password at the change password dialog.
A vulnerability was discovered where a user can execute a remote code execution attack against a server when phpMyAdmin is being run as a CGI application. Under certain server configurations, a user can pass a query string which is executed as a command-line argument by shell scripts.
For Debian 7 "Wheezy", these problems have been fixed in version 126.96.36.199-2+deb7u6.
We recommend that you upgrade your phpmyadmin packages.
