Buffer Overflow vulnerability in NBD80S09S-KLC v.YK_HZXM_NBD80S09S-KLC_V4.03.R11.7601.Nat.OnvifC.20230414.bin and NBD80N32RA-KL-V3 v.YK_HZXM_NBD80N32RA-KL_V4.03.R11.7601.Nat.OnvifC.20220120.bin allows a remote attacker to casue a denial of service via a crafted request to the service.XM component.

Multiple Xiongmai NVR devices, including MBD6304T V4.02.R11.00000117.10001.131900.00000 and NBD6808T-PL V4.02.R11.C7431119.12001.130000.00000, allow an unauthenticated and remote user to exploit a stack-based buffer overflow and crash the web server, resulting in a system reboot. An unauthenticated and remote attacker can execute arbitrary code by sending a crafted HTTP request that triggers the overflow condition via a long URI passed to a sprintf call. NOTE: this is different than CVE-2018-10088, but this may overlap CVE-2017-16725.

Multiple Xiongmai NVR devices, including MBD6304T V4.02.R11.00000117.10001.131900.00000 and NBD6808T-PL V4.02.R11.C7431119.12001.130000.00000, allow authenticated users to execute arbitrary commands as root, as exploited in the wild starting in approximately 2019. A remote and authenticated attacker, possibly using the default admin:tlJwpbo6 credentials, can connect to port 34567 and execute arbitrary operating system commands via a crafted JSON file during an upgrade request. Since at least 2021, Xiongmai has applied patches to prevent attackers from using this mechanism to execute telnetd.

Xiongmai Camera XM-JPR2-LX V4.02.R12.A6420987.10002.147502.00000 is vulnerable to plain-text traffic sniffing.

Xiongmai Camera XM-JPR2-LX V4.02.R12.A6420987.10002.147502.00000 is vulnerable to account takeover.

Xiongmai Technology Co devices AHB7008T-MH-V2, AHB7804R-ELS, AHB7804R-MH-V2, AHB7808R-MS-V2, AHB7808R-MS, AHB7808T-MS-V2, AHB7804R-LMS, and HI3518E_50H10L_S39 were all discovered to have port 9530 open which allows unauthenticated attackers to make arbitrary Telnet connections with the victim device.

A buffer over flow in Xiongmai DVR devices NBD80X16S-KL, NBD80X09S-KL, NBD80X08S-KL, NBD80X09RA-KL, AHB80X04R-MH, AHB80X04R-MH-V2, AHB80X04-R-MH-V3, AHB80N16T-GS, AHB80N32F4-LME, and NBD90S0VT-QW allows attackers to cause a Denial of Service (DoS) via a crafted RSTP request.

An issue was discovered on XiongMai Besder IP20H1 V4.02.R12.00035520.12012.047500.00200 cameras. An attacker on the same local network as the camera can craft a message with a size field larger than 0x80000000 and send it to the camera, related to an integer overflow or use of a negative number. This then crashes the camera for about 120 seconds.

All versions of Hangzhou Xiongmai Technology Co., Ltd XMeye P2P Cloud Server may allow an attacker to use MAC addresses to enumerate potential Cloud IDs. Using this ID, the attacker can discover and connect to valid devices using one of the supported apps.
