This issue arises due to insufficient validation of the 'filename' request parameter, which is used during file handling operations. An authenticated attacker can manipulate this parameter by injecting directory traversal sequences (e.g., ../) to escape the intended upload or application directories. Successful exploitation allows the attacker to delete arbitrary files across the application installation, including system-critical resources like CSS, XML, and JSON configuration files, or sensitive documents belonging to other users. This vulnerability represents a significant risk to application integrity and data confidentiality, as it enables destructive actions against the underlying file system within the scope of the web application user.</p>
<h2 id="impact">Impact</h2>
<p>Successful exploitation results in the unauthorized deletion of arbitrary files within the web root and potentially the wider application directory, leading to service disruption, loss of configuration, or data loss. The vulnerability affects the confidentiality and availability of the RosarioSIS installation.</p>
<h2 id="recommendation">Recommendation</h2>
<p>Prioritized actions for security and IT operations teams:</p>
<ul>
<li>Upgrade RosarioSIS to version 12.9 or later immediately to incorporate the required filename validation patches.</li>
<li>Audit access logs for web requests containing directory traversal sequences (e.g., &quot;..%2f&quot; or &quot;../&quot;) targeting the Users or Students modules.</li>
<li>Implement restrictive file system permissions to ensure the web server user only has write access to designated upload directories, preventing unauthorized deletion of system files.</li>
</ul>
