Deeper analysis

CVE-2025-8456 is an Improper Neutralization of Input During Web Page Generation vulnerability, enabling Reflected Cross-site Scripting (XSS), classified under CWE-79. It affects Kod8 Software Technologies Trade Ltd. Co.'s Kod8 Individual and SME Website through version 03022026.

The vulnerability carries a CVSS v3.1 base score of 7.6 (AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:H), indicating exploitation is possible over the network with low attack complexity, no privileges required, but necessitating user interaction and maintaining unchanged scope. Remote attackers can deliver malicious payloads via reflected inputs, potentially leading to limited confidentiality and integrity impacts alongside high availability disruption in the victim's browser context.

An advisory detailing the issue is published by USOM at https://www.usom.gov.tr/bildirim/tr-26-0012. No patches or vendor response are available, as the vendor was contacted early about the disclosure but did not reply.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly mitigates reflected XSS by enforcing validation mechanisms on user inputs to neutralize malicious scripts before web page generation.

SI-15 Information Output Filtering good match
prevent

Prevents reflected XSS exploitation by filtering and encoding output prior to rendering in the victim's browser, blocking script execution.

SI-9 Information Input Restrictions good match
prevent

Restricts maliciously formed inputs at entry points, preventing the injection of XSS payloads into the Kod8 website's reflected responses.
