CWEhttps://cwe.mitre.org/data/definitions/134.html

PHP 4.4.4, 5.1.6, and other versions, when running on Apache, allows local users to modify behavior of other sites hosted on the same web server by modifying the mbstring.func_overload setting within .htaccess, which causes this setting to be applied to other virtual hosts on the same server.

Weakness

The product uses a function that accepts a format string as an argument, but the format string originates from an external source.
