Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly mitigates the vulnerability by validating and sanitizing the 'Xml' parameter in POST requests to /public/cgi/Gateway.php to prevent malicious content injection.

SI-7 Software, Firmware, and Information Integrity good match

prevent

Enforces software and information integrity checks to verify data authenticity before processing, addressing the core insufficient verification flaw in CWE-345.

SI-9 Information Input Restrictions partial match

prevent

Restricts the types and formats of inputs to the vulnerable endpoint, limiting the ability to inject unauthorized XML content for email modification.

Why these techniques?

Direct unauthenticated exploitation of a public-facing web endpoint (/public/cgi/Gateway.php) to tamper with password-reset email content.

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1

NVD Description

Insufficient data authenticity verification vulnerability in Janto, versions prior to r12. This allows an unauthenticated attacker to modify the content of emails sent to reset the password. To exploit the vulnerability, the attacker must create a POST request by injecting…

malicious content into the ‘Xml’ parameter on the ‘/public/cgi/Gateway.php’ endpoint.

Deeper analysisAI

CVE-2025-1108 is an insufficient data authenticity verification vulnerability, classified under CWE-345, affecting Janto versions prior to r12. Published on 2025-02-07, it carries a CVSS v3.1 base score of 8.6 (AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:N). The flaw enables modification of password reset email content due to inadequate verification of data authenticity in the affected component.

An unauthenticated attacker can exploit this vulnerability over the network with low complexity and no user interaction required. By crafting a POST request to the /public/cgi/Gateway.php endpoint and injecting malicious content into the 'Xml' parameter, the attacker can alter the content of emails sent for password resets, achieving high integrity impact in a scoped attack scenario.
