CVE-2024-57480
Published: 14 January 2025
Summary
CVE-2024-57480 is a critical-severity Classic Buffer Overflow (CWE-120) vulnerability in H3C N12 Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 37.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SC-14 (Public Access Protections) and SI-10 (Information Input Validation).
Deeper analysis
CVE-2024-57480 is a buffer overflow vulnerability (CWE-120) in H3C N12 V100R005, caused by a lack of length verification in the AP configuration function. This flaw affects the web component of the device, specifically accessible via the /bin/webs endpoint.
An unauthenticated remote attacker can exploit this vulnerability by sending a specially crafted POST request to /bin/webs. Successful exploitation allows the attacker to crash the target device 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 due to network accessibility, low attack complexity, and high impact on confidentiality, integrity, and availability.

Mitigating Controls (NIST 800-53 r5) AI
Directly addresses the lack of length verification in POST requests to the AP configuration function, preventing buffer overflow exploitation.
Protects the publicly accessible web server (/bin/webs) from specially crafted POST requests using web application firewalls or similar safeguards.
Mitigates arbitrary code execution from buffer overflow via memory protections like DEP and ASLR, though it does not prevent the overflow itself.
