"The remote Cisco SPA100 Series device is affected by multiple vulnerabilities:

  - Multiple remote code execution vulnerabilities. An authenticated attacker can cause a stack overflow leading to
    control flow change in the Cisco SPA 112/122 device. (CVE-2019-15240, CVE-2019-15241, CVE-2019-15242,
    CVE-2019-15243, CVE-2019-15244, CVE-2019-15245, CVE-2019-15246, CVE-2019-15247, CVE-2019-15248, CVE-2019-15249,
    CVE-2019-15250, CVE-2019-15251, CVE-2019-15252)

  - Multiple cross-site scripting vulnerabilities. An authenticated attacker can inject javascript on the Cisco SPA
    112/122 device. (CVE-2019-12702, CVE-2019-12703)

  - An arbitrary file disclosure vulnerability. An unauthenticated attacker can read any file on the device and
    elevate local privilege. (CVE-2019-12704)

  - Multiple privilege escalation vulnerabilites. An authenticated attacker can leak the administrator password
    hash to escalate local privilege. (CVE-2019-12708, CVE-2019-15257)

  - A denial of service vulnerability. An authenticated attacker can crash the web service with a malformed
    request. (CVE-2019-12258)");
