Summary
A buffer overflow vulnerability was found in the H3C N12 V100R005 device within the 2.4G wireless network processing function. The lack of length validation allows an attacker to remotely crash the device or execute arbitrary code by sending a POST request to /bin/webs.
Risk Assessment
The risk includes remote code execution, which could lead to network compromise, data leakage, or using the device as a pivot for further attacks.
Recommendation
Immediately update the H3C N12 firmware to the latest patched version. If unavailable, restrict management interface access to trusted networks only.
Other vulnerabilities in H3C N12
See all- CVE-2024-57473Critical
A buffer overflow vulnerability was discovered in the H3C N12 device running firmware version V100R005, specifically in the MAC address editing function. The lack of input length validation allows an attacker to send a crafted POST request to /bin/webs, potentially causing a device crash or arbitrary code execution.
- CVE-2024-57482Critical
A buffer overflow vulnerability was found in the H3C N12 V100R005 device within the 5G wireless network processing function. The lack of length validation allows an attacker to remotely crash the device or execute arbitrary commands by sending a POST request to /bin/webs.
- CVE-2024-57480Critical
A buffer overflow vulnerability was found in the H3C N12 V100R005 device in the AP configuration function. The lack of length validation allows an attacker to remotely crash the device or execute arbitrary commands by sending a POST request to /bin/webs.
- CVE-2024-57479Critical
A buffer overflow vulnerability was found in the H3C N12 V100R005 device in the MAC address update function. Lack of length validation allows an attacker to remotely crash the device or execute arbitrary code by sending a POST request to /bin/webs.
Original NVD description (English source)
H3C N12 V100R005 contains a buffer overflow vulnerability due to the lack of length verification in the 2.4G 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.
