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.
Security readout for executives and security teams
Plain-English summary
CVE-2024-57479 is a critical flaw reported in H3C N12 V100R005. A remote, unauthenticated attacker could crash the device or run arbitrary commands. This creates business risk for network availability and possible device takeover. The sources do not identify a vendor patch or confirm active exploitation.
Executive priority
High priority for organizations with H3C N12 V100R005, especially if remotely reachable. Prioritize exposure reduction and vendor confirmation because potential impact includes device outage and command execution, but public sources do not name a patch or active exploitation.
Technical view
The CVE describes a CWE-120 buffer overflow caused by missing length validation in the MAC address update function. Exploitation is reported via a crafted POST request to the device web service. CVSS is 9.8, with network attack vector, low complexity, no privileges, no user interaction, and high confidentiality, integrity, and availability impact.
Likely exposure
Organizations using H3C N12 devices running V100R005 are the apparent exposure group. The CVE’s structured affected-product metadata is incomplete, so confirm firmware and model directly from asset inventory and vendor documentation. Internet-exposed management interfaces would materially increase risk.
Exploitation context
CISA KEV is not indicated in the provided data, and no cited source confirms active exploitation. Public technical details exist in the reference gist, so defenders should treat exposure as urgent while avoiding assumptions about real-world exploitation.
Researcher notes
The CVE record names H3C N12 V100R005 and describes unauthenticated remote impact, but structured affected fields are not populated. The public reference appears to contain technical exploit context. Avoid relying on inferred product ranges beyond the named version until vendor data is available.
Mitigation direction
Check H3C guidance for fixed firmware or official mitigations.
Restrict device management access to trusted administrative networks.
Remove any internet exposure for the web management interface.
Apply compensating controls until vendor remediation is confirmed.
Monitor affected devices for crashes, reboots, or suspicious management requests.
Validation and detection
Inventory H3C N12 devices and record firmware versions.
Confirm whether any device runs V100R005.
Review firewall and routing paths to management interfaces.
Check vendor channels for advisories or updated firmware.
Review logs for abnormal web management activity and device instability.
