What is CVE-2003-0259?
The vulnerability allows remote attackers to exploit a flaw in the SSH initialization process on Cisco VPN 3000 series concentrators and the Cisco VPN 3002 Hardware Client. By sending a specially crafted SSH initialization packet, an attacker can trigger a reload of the affected devices, resulting in service disruption and unavailability. This highlights the importance of secure configurations and timely updates to mitigate the risks posed by malformed traffic.
