CVE-2026-27847 has a CVSS 3.1 base score of 9.8 (Critical). CVSS vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H. EPSS exploitation probability: 0.1%.

How to fix or mitigate CVE-2026-27847?

Within 24 hours: Identify all systems using TLS-SRP authentication and assess exposure; isolate or disable TLS-SRP services if business operations permit. Within 7 days: Implement network segmentation to restrict TLS-SRP endpoint access, enforce strict input validation at application layer, and deploy enhanced monitoring for suspicious authentication attempts. Within 30 days: Evaluate vendor roadmap for patch availability; consider migrating to alternative authentication mechanisms (OAuth 2.0, certificate-based auth) if TLS-SRP is non-critical; conduct security assessment of affected systems for unauthorized access.

CRITICAL 9.8

DescriptionCVE.org

Due to improper neutralization of special elements, SQL statements can be injected via the handshake of a TLS-SRP connection. This can be used to inject known credentials into the database that can be utilized to successfully complete the handshake and use the protected service. This issue affects MR9600: 1.0.4.205530; MX4200: 1.0.13.210200.

AnalysisAI

SQL injection via TLS-SRP handshake. Attacker can inject SQL through the SRP username field during TLS handshake, compromising any application using TLS-SRP authentication.

Technical ContextAI

CWE-89 SQL injection through the SRP username in TLS-SRP handshake. The SRP identity (username) is passed unsanitized to SQL queries during authentication.
