Summary

CVE-2024-30372 is a medium-severity Improper Neutralization of Special Elements Used in a Template Engine (CWE-1336) vulnerability in Alltena Allegra. Its CVSS base score is 6.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Template Injection (T1221); ranked in the top 37% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

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.

Allegra contains a server-side template injection vulnerability in the getLinkText method that permits remote code execution on affected installations. The flaw stems from insufficient validation of user-supplied input before it is processed by the template engine, allowing code execution in the context of the LOCAL SERVICE account. The issue was reported as ZDI-CAN-23609 and carries a CVSS 3.1 score of 6.3.

An authenticated remote attacker can supply a crafted string to the vulnerable method and achieve arbitrary code execution on the target system. No user interaction is required beyond valid credentials, and the attack can be performed over the network with low complexity.

Vendor release notes for Allegra 7.5.2 and the corresponding Zero Day Initiative advisory ZDI-24-1165 address the issue and indicate that an update resolves the template-injection flaw. The EPSS score remains low with negligible movement between its current value of 0.0712 and recorded peak of 0.0722.

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.
