VAR-202203-1302
Vulnerability from variot - Updated: 2023-12-18 13:37Totolink A830R V5.9c.4729_B20191112, A3100R V4.1.2cu.5050_B20200504, A950RG V4.1.2cu.5161_B20200903, A800R V4.1.2cu.5137_B20200730, A3000RU V5.9c.5185_B20201128, and A810R V4.1.2cu.5182_B20201026 were discovered to contain a command injection vulnerability in the function NTPSyncWithHost. This vulnerability allows attackers to execute arbitrary commands via the host_time parameter. Totolink A830R/A3100R/A950RG/A800R/A3000RU/A810R and other products are all routers from China Totolink Company. The vulnerability stems from the fact that the host_time parameter in the NTPSyncWithHost function fails to properly filter the special elements that construct the command

Vulnerability from variot - Updated: 2023-12-18 11:56Totolink A830R V5.9c.4729_B20191112, A3100R V4.1.2cu.5050_B20200504, A950RG V4.1.2cu.5161_B20200903, A800R V4.1.2cu.5137_B20200730, A3000RU V5.9c.5185_B20201128, and A810R V4.1.2cu.5182_B20201026 were discovered to contain a command injection vulnerability in the function CloudACMunualUpdate, via the deviceMac and deviceName parameters. This vulnerability allows attackers to execute arbitrary commands via a crafted request. Totolink A830R/A3100R/A950RG/A800R/A3000RU/A810R and other products are all routers from China Totolink Company. The vulnerability stems from the fact that the deviceName and deviceMac parameters in the CloudACMunualUpdate function fail to properly filter special elements that construct commands

This vulnerability allows attackers to execute arbitrary commands via a crafted request. Totolink A830R/A3100R/A950RG/A800R/A3000RU/A810R and other products are all routers from China Totolink Company. The vulnerability stems from the fact that the deviceName and deviceMac parameters in the CloudACMunualUpdate function fail to properly filter special elements that construct commands",
