Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly addresses the lack of length verification in the MAC address update function by requiring validation of POST request inputs to prevent buffer overflows.

SI-16 Memory Protection good match

prevent

Implements memory protections such as DEP and ASLR to mitigate arbitrary code execution or crashes from buffer overflow exploitation in the web interface.

SI-2 Flaw Remediation good match

prevent

Mandates timely remediation of the specific buffer overflow flaw in H3C N12 V100R005 via vendor patches to eliminate the vulnerability.

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?

Unauthenticated remote buffer overflow in public-facing web interface (/bin/webs) directly enables T1190 for RCE or DoS.

NVD Description

H3C N12 V100R005 contains a buffer overflow vulnerability due to the lack of length verification in the mac address update 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-2024-57479 is a buffer overflow vulnerability (CWE-120) affecting H3C N12 V100R005 due to insufficient length verification in the MAC address update function. The vulnerability resides in the web interface component, specifically accessible via the /bin/webs endpoint.

Remote attackers can exploit this vulnerability without authentication, privileges, or user interaction by sending a specially crafted POST request to the vulnerable endpoint. Successful exploitation allows attackers to cause the target device to crash, resulting in a denial of service, or execute arbitrary commands, with a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) reflecting its critical severity and high impact on confidentiality, integrity, and availability.
