Detection Guidance

[{'type': 'paragraph', 'content': 'This vulnerability can be detected by identifying instances of the vulnerable file save-games.php being accessed with the game_name parameter containing suspicious or malicious script payloads.'}, {'type': 'paragraph', 'content': 'One method to detect vulnerable targets is to use Google dorking with the query: inurl:save-games.php to find exposed instances of the affected system.'}, {'type': 'paragraph', 'content': 'To detect exploitation attempts on your system, you can monitor web server logs for requests to save-games.php that include suspicious JavaScript code or typical XSS payloads in the game_name parameter.'}, {'type': 'paragraph', 'content': 'Example command to search web server logs for potential XSS attempts (assuming Apache logs):'}, {'type': 'list_item', 'content': "grep -i 'save-games.php' /var/log/apache2/access.log | grep -i 'game_name=.*<script'"}, {'type': 'list_item', 'content': "grep -i 'save-games.php' /var/log/apache2/access.log | grep -E 'game_name=.*(\\<|%3C).*script'"}, {'type': 'paragraph', 'content': 'Additionally, you can use web vulnerability scanners that support detection of stored XSS vulnerabilities by targeting the save-games.php endpoint and testing the game_name parameter for script injection.'}] [2, 3]

Mitigation Strategies

There are no known countermeasures or mitigations documented for this vulnerability.

The suggested immediate step is to replace the affected product with an alternative that does not contain this vulnerability.

As a temporary measure, you may consider implementing web application firewall (WAF) rules to block requests containing suspicious script payloads in the game_name parameter to reduce the risk of exploitation.

Additionally, monitoring and filtering input to the save-games.php file to prevent script injection can help mitigate the risk until a secure version or alternative is deployed.
