Title: PHP/FI mylog/mlog Vulnerability
Severity: HIGH
Description:
The PHP/FI package which was originally written by Rasmus Lerdorf is an is an HTML-embedded scripting language. Much of its syntax is borrowed from C, Java and Perl with a couple of unique PHP-specific features thrown in. The goal of the language is to allow web developers to write dynamically generated pages quickly.
Since its inception, PHP/FI has been turned over to another development team and is now known only as PHP. Certain versions of PHP/FI shipped with two flawed example script for logging examples. These scripts were mylog.html & mlog.html. in both mlog.html and mylog.html. The idea is to include a file for each type of logging stats, however, there is no escaping of slashes, so one can specify any file on the system.
The problem lies in the line:
<?include "$screen">
By exploiting this problem users can view any file on the system which the http daemon user id has access to.
Affected Products:
- PHP PHP/FI 1.0.0
- PHP PHP/FI 2.0.0
- PHP PHP/FI 2.0.0b10
