PMASA-2019-1
Announcement-ID: PMASA-2019-1
Date: 2019-01-21
Summary
Arbitrary file read vulnerability
Description
When AllowArbitraryServer configuration set to true, with the use of a rogue
MySQL server, an attacker can read any file on the server that the web server's
user can access.
phpMyadmin attempts to block the use of LOAD DATA INFILE, but due to a bug in
PHP, this check is not honored. Additionally, when using the 'mysql' extension,
mysql.allow_local_infile is enabled by default. Both of these conditions allow
the attack to occur.
Severity
We consider this vulnerability to be critical.
Mitigation factor
This attack can be mitigated by setting the `AllowArbitraryServer`
configuration directive to false (which is the default value).
Affected Versions
phpMyAdmin versions from at least 4.0 through 4.8.4 are affected
Solution
Upgrade to phpMyAdmin 4.8.5 or newer or apply patch listed below.
