CVE-2026-2984 identifies a denial of service vulnerability in SourceCodester Student Result Management System version 1.0, specifically within the /admin/core/drop_user.php script. The vulnerability arises from improper handling of the ID parameter, which an attacker can manipulate remotely to cause the system to crash or become unresponsive, effectively denying service to legitimate users. The attack vector requires no authentication or user interaction, making it easier to exploit. The vulnerability affects the availability of the system, potentially disrupting access to student result management functions. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:P) indicates network attack vector, low attack complexity, no privileges or user interaction required, and partial impact on integrity and availability. Although no patches are currently linked, the presence of a public exploit increases the urgency for mitigation. The vulnerability does not affect confidentiality or system components beyond the application scope. The system is typically deployed in educational environments, making the impact focused on academic institutions relying on this software for managing student records.

The primary impact of CVE-2026-2984 is the disruption of availability of the Student Result Management System, which can halt access to critical academic data such as student grades and records. This can affect administrative operations and delay academic processes. Since the exploit requires no authentication and can be executed remotely, attackers can easily launch denial of service attacks, potentially causing repeated outages. The vulnerability does not directly compromise confidentiality or integrity but the loss of availability can have operational and reputational consequences for educational institutions. Organizations relying on this system may face interruptions in service, impacting students, faculty, and administrative staff. The medium severity rating reflects the moderate impact and ease of exploitation, but the scope is limited to environments using this specific software version.

To mitigate CVE-2026-2984, organizations should immediately implement strict input validation and sanitization on the ID parameter in /admin/core/drop_user.php to prevent malicious manipulation. Until an official patch is released, consider deploying web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the vulnerable endpoint. Restrict network access to the administrative interface by IP whitelisting or VPN enforcement to reduce exposure. Monitor logs for unusual activity related to the drop_user.php script to identify potential exploitation attempts. Educate system administrators about the vulnerability and ensure backups of critical data are maintained to facilitate recovery in case of service disruption. Once a vendor patch becomes available, prioritize timely application to fully remediate the issue. Additionally, consider isolating the affected system within the network to limit potential impact.
