Vulnerabilities in this advisory
- CVE-2025-40815 — CVE-2025-40815 · 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-2025-40816 — CVE-2025-40816 · CWE-306
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.
- CVE-2025-40817 — CVE-2025-40817 · CWE-306
Affected devices do not conduct certain validations when interacting with them. This could allow an unauthenticated remote attacker to change time of the device, which means the device could behave differently.
