The vulnerabilities impression the next gadgets —

  • Catalyst PON Change CGP-ONT-1P
  • Catalyst PON Change CGP-ONT-4P
  • Catalyst PON Change CGP-ONT-4PV
  • Catalyst PON Change CGP-ONT-4PVC
  • Catalyst PON Change CGP-ONT-4TVCW

Marco Wiorek of Hotzone GmbH has been credited with reporting the three vulnerabilities which have been assigned the identifiers CVE-2021-34795 (CVSS rating: 10.0), CVE-2021-40113 (CVSS rating: 10.0), and CVE-2021-40112 (CVSS rating: 8.6).

Prevent Data Breaches

Lastly, Cisco has remediated two extra high-severity flaws in Cisco Small Enterprise Sequence Switches and Cisco AsyncOS that would permit unauthenticated, distant adversaries to realize unauthorized entry to the web-based administration interface of the switches and perform a denial of service (DoS) assault —

  • CVE-2021-34739 (CVSS rating: 8.1) – Cisco Small Enterprise Sequence Switches session credentials replay vulnerability
  • CVE-2021-34741 (CVSS rating: 7.5) – Cisco Electronic mail Safety Equipment (ESA) denial of service vulnerability
