The FTP server on Cisco Content Service 11000 series switches (CSS) before WebNS 4.01B23s and WebNS 4.10B13s allows an attacker who is an FTP user to read and write arbitrary files via GET or PUT commands.
CVE-2001-0566 1 Cisco 1 Catalyst 2900 2026-06-16 5.0 MEDIUM N/A
Cisco Catalyst 2900XL switch allows a remote attacker to create a denial of service via an empty UDP packet sent to port 161 (SNMP) when SNMP is disabled.
CVE-2001-0537 1 Cisco 1 Ios 2026-06-16 9.3 HIGH N/A
HTTP server for Cisco IOS 11.3 to 12.2 allows attackers to bypass authentication and execute arbitrary commands, when local authorization is being used, by specifying a high access level in the URL.
CVE-2001-0455 1 Cisco 1 Aironet 340 2026-06-16 7.5 HIGH N/A
Cisco Aironet 340 Series wireless bridge before 8.55 does not properly disable access to the web interface, which allows remote attackers to modify its configuration.
CVE-2001-0444 1 Cisco 1 Cbos 2026-06-16 2.1 LOW N/A
Cisco CBOS 2.3.0.053 sends output of the "sh nat" (aka "show nat") command to the terminal of the next user who attempts to connect to the router via telnet, which could allow that user to obtain sensitive information.
CVE-2001-0429 1 Cisco 1 Catos 2026-06-16 5.0 MEDIUM N/A
Cisco Catalyst 5000 series switches 6.1(2) and earlier will forward an 802.1x frame on a Spanning Tree Protocol (STP) blocked port, which causes a network storm and a denial of service.
CVE-2001-0428 1 Cisco 1 Vpn 3000 Concentrator Series Software 2026-06-16 5.0 MEDIUM N/A
Cisco VPN 3000 series concentrators before 2.5.2(F) allow remote attackers to cause a denial of service via an IP packet with an invalid IP option.
