Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-14 Permitted Actions Without Identification or Authentication good match

prevent

Prohibits sensitive actions like privilege escalation in the web management interface without identification or authentication, directly mitigating the improper authentication vulnerability.

IA-8 Identification and Authentication (Non-organizational Users) good match

prevent

Requires identification and authentication for non-organizational users, preventing remote unauthenticated attackers from exploiting the management interface for privilege escalation.

AC-3 Access Enforcement good match

prevent

Enforces approved authorizations for access to system resources, countering the failure to properly enforce authentication in crafted HTTP requests leading to privilege escalation.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

Why these techniques?

Remote unauthenticated exploitation of web management interface (T1190) enables privilege escalation to gain full device control (T1068).

NVD Description

Improper authentication in the web-based management interface of NETLINK HG322G V1.0.00-231017, allows a remote unauthenticated attacker to escalate privileges and lock out the legitimate administrator via crafted HTTP requests.

Deeper analysisAI

CVE-2025-60772 is an improper authentication vulnerability (CWE-287) in the web-based management interface of the NETLINK HG322G router running firmware version V1.0.00-231017. Published on 2025-10-21, it has a CVSS v3.1 base score of 9.8 (Critical), reflecting network accessibility, low attack complexity, no required privileges or user interaction, and high impact on confidentiality, integrity, and availability.

A remote unauthenticated attacker can exploit this vulnerability by sending crafted HTTP requests to the management interface, enabling privilege escalation and the ability to lock out the legitimate administrator. Successful exploitation grants the attacker administrative control over the device, potentially allowing full compromise including unauthorized access to configurations, data, and network functions.
