The vulnerability identified as CVE-2025-6079 affects the dasinfomedia School Management System plugin for WordPress, specifically in the homework.php file. The core issue is the absence of proper file type validation when users upload files, classified under CWE-434 (Unrestricted Upload of File with Dangerous Type). This allows authenticated users with at least Student-level access to upload arbitrary files, including potentially malicious scripts, to the web server hosting the WordPress site. Because the plugin does not restrict or sanitize the file types, attackers can upload executable files such as PHP scripts. Once uploaded, these files can be executed remotely, leading to remote code execution (RCE). The vulnerability is remotely exploitable over the network without requiring user interaction beyond authentication, making it easier for attackers who have compromised or legitimately possess student credentials to escalate their privileges or compromise the entire server. The CVSS v3.1 score of 8.8 reflects the high impact on confidentiality, integrity, and availability, with low attack complexity and privileges required. The vulnerability affects all versions up to 93.2.0, and no official patches or fixes have been linked yet. While no known exploits have been reported in the wild, the risk remains significant due to the nature of the vulnerability and the widespread use of WordPress in educational environments. The plugin’s role in managing school homework submissions makes it a critical target for attackers aiming to disrupt educational services or steal sensitive data.

The impact of CVE-2025-6079 is substantial for organizations using the dasinfomedia School Management System plugin on WordPress, especially educational institutions. Successful exploitation can lead to remote code execution, allowing attackers to execute arbitrary commands on the server, potentially leading to full system compromise. This can result in data breaches involving student and staff personal information, unauthorized modification or deletion of educational records, disruption of school operations, and deployment of malware or ransomware. The vulnerability undermines confidentiality by exposing sensitive data, integrity by allowing unauthorized changes, and availability by potentially causing denial of service. Since the vulnerability requires only low-level authenticated access, attackers who gain student credentials through phishing or other means can escalate their privileges and compromise the entire system. The widespread use of WordPress and this plugin in schools globally increases the attack surface. Additionally, compromised educational systems can be leveraged as footholds for broader network intrusions within educational or governmental networks.

To mitigate CVE-2025-6079, organizations should immediately restrict file upload capabilities within the plugin by implementing strict server-side validation to allow only safe file types (e.g., PDFs, images) and reject executable or script files. Until an official patch is released, administrators should consider disabling the homework upload feature or restricting it to trusted users only. Employing web application firewalls (WAFs) with rules to detect and block malicious file uploads can provide an additional layer of defense. Limit user privileges rigorously, ensuring that only necessary roles have upload permissions, and enforce strong authentication mechanisms to reduce the risk of credential compromise. Regularly monitor server logs and file directories for unusual or unauthorized file uploads. Isolating the WordPress environment using containerization or sandboxing can help contain potential exploitation. Finally, maintain up-to-date backups of all critical data to enable recovery in case of compromise. Organizations should also stay alert for official patches or updates from dasinfomedia and apply them promptly once available.
