Assigner: VulnCheck

Description
WDR201A WiFi Extender (HW V2.1, FW LFMZX28040922V1.02) contains an OS command injection vulnerability in the adm.cgi binary's reboot_time function that allows unauthenticated remote attackers to execute arbitrary shell commands by injecting malicious input into the reboot_time POST parameter. Attackers can send a crafted request with shell metacharacters in the reboot_time parameter when reboot_enabled=1 to achieve remote code execution.

Executive Summary

This vulnerability exists in the WDR201A WiFi Extender (HW V2.1, FW LFMZX28040922V1.02) within the adm.cgi binary's reboot_time function. It is an OS command injection flaw that allows unauthenticated remote attackers to execute arbitrary shell commands by injecting malicious input into the reboot_time POST parameter.

Attackers can exploit this by sending a specially crafted request containing shell metacharacters in the reboot_time parameter when reboot_enabled is set to 1, resulting in remote code execution on the device.

Impact Analysis

This vulnerability can have severe impacts as it allows unauthenticated remote attackers to execute arbitrary commands on the affected device.

  • Attackers could take full control of the WiFi extender remotely.
  • They could disrupt network operations by rebooting or altering device behavior.
  • It could be used as a foothold to launch further attacks within the network.
