Title: phpMyAdmin: Multiple vulnerabilities (GLSA 200407-22)
Severity: normal
Exploitable: remote
Date: July 29, 2004
Updated: May 22, 2006
Bug(s): #57890
ID: 200407-22

Synopsis


Multiple vulnerabilities in phpMyAdmin may allow a remote attacker with a
valid user account to alter configuration variables and execute arbitrary
PHP code.


Background


phpMyAdmin is a popular, web-based MySQL administration tool written in
PHP. It allows users to administer a MySQL database from a web-browser.


Affected Packages

Package: dev-db/phpmyadmin
Vulnerable: <= 2.5.7
Unaffected: >= 2.5.7_p1
Architectures: All supported architectures


Description


Two serious vulnerabilities exist in phpMyAdmin. The first allows any
user to alter the server configuration variables (including host, name,
and password) by appending new settings to the array variables that
hold the configuration in a GET statement. The second allows users to
include arbitrary PHP code to be executed within an eval() statement in
table name configuration settings. This second vulnerability is only
exploitable if $cfg['LeftFrameLight'] is set to FALSE.


Impact


Authenticated users can alter configuration variables for their running
copy of phpMyAdmin. The impact of this should be minimal. However, the
second vulnerability would allow an authenticated user to execute
arbitrary PHP code with the permissions of the webserver, potentially
allowing a serious Denial of Service or further remote compromise.


Workaround


The second, more serious vulnerability is only exploitable if
$cfg['LeftFrameLight'] is set to FALSE. In the default Gentoo
installation, this is set to TRUE. There is no known workaround for the
first.


Resolution


All phpMyAdmin users should upgrade to the latest version:
