Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Directly mitigates the buffer overflow vulnerability by requiring timely remediation through vendor patches for the affected H3C N12 web interface.

SI-10 Information Input Validation good match

prevent

Requires validation of POST request inputs including length checks to prevent buffer overflows in the 5G wireless network processing function.

SI-16 Memory Protection good match

prevent

Implements memory safeguards such as DEP and ASLR to protect against arbitrary code execution or crashes from buffer overflow exploitation.

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?

Buffer overflow in public web interface (/bin/webs) allows unauthenticated remote RCE/DoS via crafted POST, directly enabling T1190 Exploit Public-Facing Application.

NVD Description

H3C N12 V100R005 contains a buffer overflow vulnerability due to the lack of length verification in the 5G wireless network processing function. Attackers who successfully exploit this vulnerability can cause the remote target device to crash or execute arbitrary commands…

by sending a POST request to /bin/webs.

Deeper analysisAI

CVE-2024-57482 is a buffer overflow vulnerability (CWE-120) affecting H3C N12 V100R005, caused by a lack of length verification in the 5G wireless network processing function. The vulnerability resides in the web interface component accessible at /bin/webs, where improper handling of input can lead to memory corruption. Published on 2025-01-14, it has a CVSS v3.1 base score of 9.8, reflecting its critical severity.

Unauthenticated remote attackers can exploit this vulnerability by sending a specially crafted POST request to /bin/webs on a vulnerable device. Successful exploitation allows the attacker to cause a denial-of-service condition by crashing the remote target device or, in more severe cases, execute arbitrary commands, granting high levels of confidentiality, integrity, and availability impact.

Mitigation guidance is available in vendor advisories and related resources, including the H3C security bulletin at http://h3c.com and a detailed analysis in the GitHub gist at https://gist.github.com/XiaoCurry/d39f76a025df8b78a5f9e1aa48c16d18.
