- Summary
- Information disclosure of source code in SimpleSAMLphp
- Details
-
Background
The module controller in
SimpleSAML\Modulethat processes requests for pages hosted by modules, has code to identify paths ending with.phpand process those as PHP code. If no other suitable way of handling the given path exists it presents the file to the browser.Description
The check to identify paths ending with
.phpdoes not account for uppercase letters. If someone requests a path ending with e.g..PHPand 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.Affected versions
SimpleSAMLphp versions 1.18.5 and older.
Impact
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.
Resolution
Upgrade the SimpleSAMLphp installation to version 1.18.6.
