The server management software module of ZTE has an authentication issue vulnerability, which allows users to skip the authentication of the server and execute some commands for high-level users. This affects: <R5300G4V03.08.0100/V03.07.0300/V03.07.0200/V03.07.0108/V03.07.0100/V03.05.0047/V03.05.0046/V03.05.0045/V03.05.0044/V03.05.0043/V03.05.0040/V03.04.0020;R8500G4V03.07.0103/V03.07.0101/V03.06.0100/V03.05.0400/V03.05.0020;R5500G4V03.08.0100/V03.07.0200/V03.07.0100/V03.06.0100>. ZTE Server management software contains an authentication vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. Shenzhen Zhongxing Mobile Communication Co., Ltd. was established in 2002 and is headquartered in Shenzhen High-tech Industrial Park. It is a national high-tech enterprise. There is an unauthorized access vulnerability in the ZTE server, which can be exploited by attackers to gain server permissions.
