VAR-200212-0703

Vulnerability from variot - Updated: 2024-05-17 22:50

Cisco AS5350 IOS 12.2(11)T with access control lists (ACLs) applied and possibly with ssh running allows remote attackers to cause a denial of service (crash) via a port scan, possibly due to an ssh bug. NOTE: this issue could not be reproduced by the vendor. The Cisco AS5350 Universal Gateway is reported to be prone to a denial of service condition. It is possible to cause this condition by portscanning a vulnerable device. This issue was reported for Cisco AS5350 devices running Cisco IOS release 12.2(11)T. Other firmware and devices may also be affected. There are conflicting reports regarding the existence of this vulnerability. Other sources have indicated that the issue may be related to a configuration problem. Attackers can use the Nmap scanner to scan the ports 1-65535 of the Cisco AS5350 Universal Gateway, which can cause the system to hang and require a restart of the device to obtain normal functions. However, there are many different views on this issue. improper
