The vulnerability resides within the HTTP POST Request Handler, specifically affecting an unknown function of the /viva/update.php file. Attackers can remotely exploit this flaw by manipulating the Name argument in a POST request. This improper authorization can lead to unauthorized access or privilege escalation. The exploit is publicly known, increasing the risk of widespread exploitation. The vendor employs a rolling release model, hindering identification of specific affected or patched versions. The vendor has not responded to vulnerability reports.

Attack Chain

1. Attacker identifies a vulnerable Cyber-III Student-Management-System instance exposed to the internet.
2. Attacker crafts a malicious HTTP POST request targeting the /viva/update.php endpoint.
3. The crafted request includes a modified Name parameter designed to bypass authorization checks.
4. The server-side application fails to properly validate the Name parameter, leading to improper authorization.
5. Attacker gains unauthorized access to sensitive functions within the application.
6. The attacker escalates privileges, potentially gaining administrative control over the system.
7. Attacker modifies student records, alters grades, or performs other malicious actions.
8. Attacker maintains persistence by creating a new administrative account or modifying existing ones.

Impact

Successful exploitation of CVE-2026-5642 allows attackers to escalate privileges within the Cyber-III Student-Management-System, potentially affecting all student and faculty data. This can lead to unauthorized access, data breaches, modification of records, and disruption of educational services. Given the public availability of the exploit, numerous educational institutions and organizations using the vulnerable system are at risk.

Recommendation

• Inspect web server logs for POST requests to /viva/update.php containing suspicious Name parameter values to detect exploitation attempts using the "Cyber-III Update PHP Post Request" Sigma rule.
• Implement input validation and sanitization on the Name parameter within the /viva/update.php file to prevent improper authorization.
• Deploy the "Cyber-III Suspicious Update PHP Access" Sigma rule to detect unusual access patterns to the /viva/update.php endpoint.
• Monitor web server logs for abnormal HTTP status codes (e.g., 302, 403, 500) in response to POST requests targeting /viva/update.php, as these may indicate exploitation attempts.

The vulnerability resides within the /login.php file, specifically affecting the handling of the Password parameter. Attackers can exploit this vulnerability remotely to inject malicious SQL code, potentially gaining unauthorized access to sensitive data or manipulating the application's database. The exploit is publicly available, increasing the risk of widespread exploitation. The affected product uses rolling releases; therefore, specific affected and updated versions are not available. The project has been notified of the vulnerability but has not yet responded.

Attack Chain

1. The attacker identifies a Cyber-III Student-Management-System instance accessible over the network.
2. The attacker sends a crafted HTTP POST request to /login.php, targeting the Password parameter.
3. The Password parameter contains a malicious SQL payload designed to bypass authentication or extract data.
4. The application fails to properly sanitize or validate the Password parameter before using it in a SQL query.
5. The injected SQL code is executed against the application's database.
6. The attacker successfully authenticates without valid credentials or retrieves sensitive data, such as user credentials or student records.
7. The attacker uses the compromised credentials or data to further compromise the system or other connected systems.
8. The attacker may exfiltrate sensitive data, modify records, or disrupt system operations.

Impact

Successful exploitation of this SQL injection vulnerability can lead to unauthorized access to sensitive student data, including personal information, grades, and financial records. Attackers could potentially modify or delete data, disrupt system operations, or gain control of the entire Student-Management-System. Given the lack of specific version information and the public availability of the exploit, organizations using Cyber-III Student-Management-System are at immediate risk.

Recommendation

• Inspect web server logs for suspicious POST requests to /login.php containing SQL injection payloads (see example Sigma rule below).
• Implement input validation and sanitization on the Password parameter in /login.php to prevent SQL injection (reference CVE-2026-5669).
• Monitor database logs for unauthorized access attempts or data modification originating from the web server (requires database auditing).
• Deploy the Sigma rules in this brief to your SIEM and tune for your environment.
