Vulnerability

An attacker can easily exploit this vulnerability by injecting OS commands into the web application if it does not properly sanitize its HTTP parameters. In Zeroshell 3.9.0, a Linux router, this vulnerability allows the attacker to execute code remotely.

Mitigation / Precaution

  • Properly sanitize the parameters.
  • We suggest you to update Zeroshell to a version greater than 3.9.2 in order to fix this vulnerability.

Sooraj was probably the kid who opened up a remote control just to see what was inside, then had to figure out how to put it back together before anyone noticed.
