CVE-2002-2159 describes a critical vulnerability in Linksys EtherFast Cable/DSL routers (BEFSR11, BEFSR41, BEFSRU31) running firmware 1.42.7. This flaw causes TCP port 5678 to remain open for remote administration, even when security features like "Block WAN" and "Remote Admin" are disabled, allowing unauthorized remote access. With a CVSS score of 10.0, this vulnerability is highly severe, indicating a network-based attack with low complexity, requiring no authentication, and leading to complete compromise of confidentiality, integrity, and availability. While no active exploitation, public exploit code, or significant community discussion has been identified, the high risk score and potential for full system control warrant attention.
