CVE-2002-0741

CVE-2002-0741 describes a denial-of-service vulnerability in psyBNC version 2.3. An unauthenticated remote attacker can exploit this by sending a PASS command with an excessively long password and then quickly terminating the connection, leading to high CPU consumption and resource exhaustion on the affected server. With a CVSS score of 5.0 (AV:N/AC:L/Au:N/C:N/I:N/A:P), this vulnerability is easily exploitable over the network with low attack complexity, resulting in a partial denial of service. While not listed on CISA's KEV catalog, exploit code is publicly available on ExploitDB, though there is no evidence of active exploitation or significant community discussion.
