Description
DHCP on Linksys BEFSR11, BEFSR41, BEFSR81, and BEFSRU31 Cable/DSL Routers, firmware version 1.45.7, does not properly clear previously used buffer contents in a BOOTP reply packet, which allows remote attackers to obtain sensitive information. Impacted versions: 1.43, 1.44, 1.40.2, 1.42.7, 1.41, 1.43.3, 1.42.3 Base Score: 5.0, Severity: MEDIUM, ID: CVE-2004-0580, Last Modified: 2018-08-13T21:47:00Z References Broken Link Exploit Exploit
