SimpleSAMLphp versions before 1.18.6 contain an information disclosure vulnerability. 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. 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. This issue is fixed in version 1.18.6.
CVE-2020-5301
This low-severity CVE scores 3.0 under NVD CVSS v3. EPSS exploit probability: 0.1%, top 66% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
