Vulnerability Description

A vulnerability was identified in hemant6488 CodeIgniter-StudentManagementSystem. The impacted element is the function addStudent of the file view_students.php of the component Students Controller. The manipulation of the argument Name leads to cross site scripting. The attack is possible to be carried out remotely. The exploit is publicly available and might be used. This product adopts a rolling release strategy to maintain continuous delivery. Therefore, version details for affected or updated releases cannot be specified. The project was informed of the problem early through an issue report but has not responded yet.

Recommended Actions

1. Maintain the observed Atomicorp protections. Keep your Atomicorp commercial rules current and confirm that the selected observed rules (333140 , 333141 , 340095 , 340147 , 340148 , 341256 , 342259 , 346755 , 350147 , 350148 ) have not been locally disabled. Atomicorp commercial rules are enabled by default. If you use Atomic WAF, review the applicable policy and rule settings.

2. Apply the vendor’s remediation. WAF protection is defense in depth and does not replace upgrading or following the affected vendor’s guidance.

   • Affected versions: hemant6488 CodeIgniter-StudentManagementSystem version 9abd69448c66555d434755e6bd0b099a8527a0a9.
   • Affected versions: hemant6488 CodeIgniter-StudentManagementSystem version 9157e0c28b177fdbe69cf76e878eca365fedbf5f.
   • Affected versions: hemant6488 CodeIgniter-StudentManagementSystem version f2e07d2ecd007fa1429f0444510ad95a8d0d7c73.
   • No specific CNA/vendor solution or workaround is included in the current CVE Record (opens in a new tab) . Review the vendor’s security advisories and supported-release guidance before making changes.

3. Validate after changes. Confirm rule updates are current, review WAF events for the affected application, and test application behavior after vendor upgrades, mitigations, or local policy changes.

Research Notes

Atomicorp WAF protections are designed around attack techniques and exploit behaviors, allowing existing protections to apply across multiple vulnerabilities without requiring a unique rule for every CVE.

Research Note Context

This research note documents exploit-technique analysis associated with this vulnerability and references Atomicorp WAF protections observed during engineering review, testing, or validation activities.

Atomicorp security controls are generally designed to identify and mitigate attack techniques and exploit behaviors rather than individual CVE identifiers. As a result, protections developed for one vulnerability may also apply to related attack variants and future vulnerabilities using similar techniques.
