The module controller in SimpleSAML\Module
that processes requests for pages
hosted by modules, has code to identify paths ending with .php
and process
those as PHP code. If no other suitable way of handling the given path exists it
presents the file to the browser.
The check to identify paths ending with .php
does not account for uppercase
letters. If someone requests a path ending with e.g. .PHP
and the server is
serving the code from a case-insensitive file system, such as on Windows, the
processing of the PHP code does not occur, and the source code is instead
presented to the browser.
SimpleSAMLphp versions 1.18.5 and older.
An attacker may use this issue to gain access to the source code in third-party
modules that is meant to be private, or even sensitive. However, the attack
surface is considered small, as the attack will only work when SimpleSAMLphp
serves such content from a file system that is not case-sensitive, such as on
Windows.
Upgrade the SimpleSAMLphp installation to version 1.18.6.
This vulnerability was discovered and reported by SΕawek NaczyΕski.
