Name of the Vulnerable Software and Affected Versions: Cisco DSL CPE devices version 2.4.4 and earlier

Description: The issue allows remote attackers to cause a denial of service, resulting in the device hanging or consuming large amounts of memory. This can be achieved by sending a large packet to the DHCP port, the Telnet port, or by flooding the CPE with large packets, which causes the TCP/IP stack to consume large amounts of memory.

Recommendations: For versions 2.4.4 and earlier, consider restricting access to the DHCP and Telnet ports to minimize the risk of exploitation. As a temporary workaround, implement rate limiting to prevent floods of large packets to the CPE.
