Detailsinfo

A vulnerability, which was classified as very critical, was found in Shenzhen Cudy TR3000 up to 2.5.41. Affected is the function luci.util.exec of the file obuspa_system.lua of the component obuspa_system. The manipulation of the argument Password with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command before it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Cudy TR3000 before 2.5.42 contains an OS command injection vulnerability that allows a malicious or compromised ACS to execute commands as root by supplying a crafted InternetGatewayDevice.User.{i}.Password value. Attackers can send a SetParameterValues request with shell metacharacters that obuspa_system.lua concatenates into a luci.util.exec() command string, gaining root command execution.
