Detailsinfo

A vulnerability, which was classified as critical, was found in Edimax EW-7438RPn Mini up to 1.13. Affected is some unknown processing of the file syscmd.asp. The manipulation of the argument sysCmd 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 when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:
