This vulnerability involves a stack-based buffer overflow in the SetMobileAPInfoById function of the H3C Magic B0 device firmware up to version 100R002. An attacker can remotely exploit this by sending crafted input to the /goform/aspForm endpoint, causing memory corruption. The CVSS 4.0 base score is 8.7, reflecting high impact with network attack vector, low attack complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability. The vendor has not issued a fix or advisory, and no patch links are available. Exploit code has been publicly disclosed but no known exploitation in the wild has been reported.

Successful exploitation of this vulnerability could allow a remote attacker to execute arbitrary code on the affected device or cause a denial of service, impacting confidentiality, integrity, and availability. Given the high CVSS score and remote attack vector without required privileges, the risk to affected systems is significant. However, there is no confirmed exploitation in the wild at this time.

No official patch or remediation is currently available from the vendor. Since the vendor has not responded and no fixes have been published, users should consider applying network-level protections such as restricting access to the affected device's management interfaces and monitoring for suspicious activity targeting the /goform/aspForm endpoint. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
