Summary

CVE-2024-24724 is a critical-severity Improper Neutralization of Special Elements Used in a Template Engine (CWE-1336) vulnerability in Gibbonedu Gibbon. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Template Injection (T1221); ranked in the top 2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Gibbon versions through 26.0.00 contain a server-side template injection vulnerability in /modules/School Admin/messengerSettings.php. Untrusted input reaches the Twig template engine without sanitization, allowing an attacker to inject template directives that execute arbitrary code on the server. The flaw is tracked as CWE-1336 and carries a CVSS 3.1 base score of 9.8.

An unauthenticated remote attacker can submit a malicious payload directly to the affected endpoint and obtain full remote code execution, including the ability to read, modify, or delete data and to pivot within the hosting environment. No credentials or user interaction are required.

The Gibbon project site provides updated releases that address the issue; administrators should upgrade and verify that the messengerSettings.php endpoint no longer processes unsanitized input. The EPSS score of 0.45 indicates substantial real-world exploitation interest since disclosure.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and static analysis can discover missing neutralization of template directives.

Input validation rejects or sanitizes untrusted data before it reaches the template engine, stopping injection of special syntax.

Security engineering principles require use of safe templating APIs and proper escaping of external input.

finds

Security testing can detect template-injection flaws but does not itself implement neutralization controls.

prevents

Secure development life cycle mandates input validation and sanitization that directly prevents template-injection weaknesses.

prevents

Application security requirements explicitly call for neutralizing special elements in template engines.

prevents

Secure architecture principles reduce the likelihood of unsafe template processing but do not prescribe specific neutralization techniques.

prevents

Secure coding standards require proper escaping or sandboxing of template directives, directly mitigating CWE-1336.
