Description
PILOS (Platform for Interactive Live-Online Seminars) is a frontend for BigBlueButton. PILOS before 4.8.0 exposes the PHP version via the X-Powered-By header, enabling attackers to fingerprint the server and assess potential exploits. This information disclosure vulnerability originates from PHP’s base image. Additionally, the PHP version can also be inferred through the PILOS version displayed in the footer and by examining the source code available on GitHub. This information disclosure vulnerability has been patched in PILOS in v4.8.0.

Executive Summary

This vulnerability in PILOS before version 4.8.0 exposes the PHP version used by the server through the X-Powered-By HTTP header. Attackers can use this information to fingerprint the server and identify potential exploits. Additionally, the PHP version can be inferred from the PILOS version shown in the footer and by examining the source code on GitHub. This is an information disclosure vulnerability that was fixed in version 4.8.0.

Impact Analysis

The vulnerability allows attackers to gain information about the server's PHP version, which can help them identify known vulnerabilities and plan targeted attacks. While it does not directly compromise data integrity or availability, it increases the risk of exploitation by revealing system details that should remain confidential.

Detection Guidance

This vulnerability can be detected by checking if the PHP version is exposed via the X-Powered-By HTTP header in responses from the PILOS frontend before version 4.8.0. You can use commands like `curl -I http://your-pilos-server` or `curl -s -D - http://your-pilos-server | grep X-Powered-By` to see if the PHP version is disclosed. Additionally, inspecting the footer of the web interface for the PILOS version or reviewing the source code on GitHub can help infer the PHP version.

Mitigation Strategies

To mitigate this vulnerability immediately, upgrade PILOS to version 4.8.0 or later where the PHP version disclosure via the X-Powered-By header has been patched. Alternatively, you can configure your web server or PHP settings to remove or hide the X-Powered-By header to prevent PHP version disclosure.
