Products, as the advisory lists them

DeSpy has not checked any unit, hardware revision or firmware.

Vulnerabilities in this advisory

• CVE-2022-36361 — CVE-2022-36361 · CWE-120

  Affected devices do not properly validate the structure of TCP packets in several methods. This could allow an attacker to cause buffer overflows, get control over the instruction counter and run custom code.

• CVE-2022-36362 — CVE-2022-36362 · CWE-20

  Affected devices do not conduct certain validations when interacting with them. This could allow an unauthenticated remote attacker to manipulate the devices IP address, which means the device would not be reachable and could only be recovered by power cycling the device.

• CVE-2022-36363 — CVE-2022-36363 · CWE-1285

  Affected devices do not properly validate an offset value which can be defined in TCP packets when calling a method. This could allow an attacker to retrieve parts of the content of the memory.
