A hard-coded weak password vulnerability has been discovered in all Magic-branded devices from Chinese network equipment manufacturer H3C. The vulnerability stems from the use of a hard-coded weak password for the root account in the /etc/shadow configuration or even the absence of any password at all. Some of these devices have the Telnet service enabled by default, or users can choose to enable the Telnet service in other device management interfaces (e.g. /debug.asp or /debug_telnet.asp). In addition, these devices have related interfaces called Virtual Servers, which can map the devices to the public network, posing the risk of remote attacks. Therefore, attackers can obtain the highest root privileges of the devices through the Telnet service using the weak password hardcoded in the firmware (or without a password), and remote attacks are possible.

H3C Magic B0 aspForm EditWlanMacList buffer overflow

A weakness has been identified in H3C Magic B0 up to 100R002. This impacts the function EditWlanMacList of the file /goform/aspForm. This manipulation of the argument param causes buffer overflow. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be exploited. The vendor was contacted early about this disclosure but did not respond in any way.

H3C devices running firmware version NX15V100R015 are vulnerable to unauthorized access due to insecure default credentials. The root user account has no password set, and the H3C user account uses the default password "admin," both stored in the /etc/shadow file. Attackers with network access can exploit these credentials to gain unauthorized root-level access to the device via the administrative interface or other network services, potentially leading to privilege escalation, information disclosure, or arbitrary code execution.

In H3C GR2200 MiniGR1A0V100R016, the USERLIMIT_GLOBAL option is set to 0 in the /etc/bftpd.conf. This can cause DoS attacks when unlimited users are connected.
