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 do not encrypt all device communication. This includes the XMeye service and firmware update communication. This could allow an attacker to eavesdrop on video feeds, steal XMeye login credentials, or impersonate the update server with malicious update code.
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.
All versions of Hangzhou Xiongmai Technology Co., Ltd XMeye P2P Cloud Server may allow an attacker to use an undocumented user account "default" with its default password to login to XMeye and access/view video streams.
A Stack-based Buffer Overflow issue was discovered in Xiongmai Technology IP Cameras and DVRs using the NetSurveillance Web interface. The stack-based buffer overflow vulnerability has been identified, which may allow an attacker to execute code remotely or crash the device. After rebooting, the device restores itself to a more vulnerable state in which Telnet is accessible.
