Multiple vulnerabilities in the H.323 protocol implementation for Cisco IOS 11.3T through 12.2T allow remote attackers to cause a denial of service and possibly execute arbitrary code, as demonstrated by the NISCC/OUSPG PROTOS test suite for the H.225 protocol.
CVE-2001-0861 1 Cisco 1 12000 Router 2026-04-16 N/A
Cisco 12000 with IOS 12.0 and line cards based on Engine 2 and earlier allows remote attackers to cause a denial of service (CPU consumption) by flooding the router with traffic that generates a large number of ICMP Unreachable replies.
CVE-2003-0512 1 Cisco 1 Ios 2026-04-16 N/A
Cisco IOS 12.2 and earlier generates a "% Login invalid" message instead of prompting for a password when an invalid username is provided, which allows remote attackers to identify valid usernames on the system and conduct brute force password guessing, as reported for the Aironet Bridge.
CVE-1999-0162 1 Cisco 1 Ios 2026-04-16 N/A
The "established" keyword in some Cisco IOS software allowed an attacker to bypass filtering.
CVE-2001-0161 1 Cisco 1 Aironet 2026-04-16 N/A
Cisco 340-series Aironet access point using firmware 11.01 does not use 6 of the 24 available IV bits for WEP encryption, which makes it easier for remote attackers to mount brute force attacks.
CVE-1999-0161 1 Cisco 1 Ios 2026-04-16 N/A
In Cisco IOS 10.3, with the tacacs-ds or tacacs keyword, an extended IP access control list could bypass filtering.
CVE-1999-0159 1 Cisco 1 Ios 2026-04-16 3.5 Low
Attackers can crash a Cisco IOS router or device, provided they can get to an interactive prompt (such as a login). This applies to some IOS 9.x, 10.x, and 11.x releases.
CVE-2001-0080 1 Cisco 3 Catalyst 4000, Catalyst 5000, Catalyst 6000 2026-04-16 N/A
Cisco Catalyst 6000, 5000, or 4000 switches allow remote attackers to cause a denial of service by connecting to the SSH service with a non-SSH client, which generates a protocol mismatch error.
CVE-2003-0259 1 Cisco 6 Vpn 3000 Concentrator Series Software, Vpn 3002 Hardware Client, Vpn 3015 Concentrator and 3 more 2026-04-16 N/A
Cisco VPN 3000 series concentrators and Cisco VPN 3002 Hardware Client 2.x.x through 3.6.7 allows remote attackers to cause a denial of service (reload) via a malformed SSH initialization packet.
CVE-1999-0157 1 Cisco 2 Ios, Pix Firewall Software 2026-04-16 N/A
Cisco PIX firewall and CBAC IP fragmentation attack results in a denial of service.
CVE-2006-0179 1 Cisco 1 Ip Phone 7940 2026-04-16 N/A
The Cisco IP Phone 7940 allows remote attackers to cause a denial of service (reboot) via a large amount of TCP SYN packets (syn flood) to arbitrary ports, as demonstrated to port 80.
CVE-2005-2244 1 Cisco 1 Call Manager 2026-04-16 N/A
The aupair service (aupair.exe) in Cisco CallManager (CCM) 3.2 and earlier, 3.3 before 3.3(5), 4.0 before 4.0(2a)SR2b, and 4.1 4.1 before 4.1(3)SR1 allows remote attackers to execute arbitrary code or corrupt memory via crafted packets that trigger a memory allocation failure and lead to a buffer overflow.
CVE-2004-1099 1 Cisco 2 Secure Access Control Server, Secure Acs Solution Engine 2026-04-16 N/A
Cisco Secure Access Control Server for Windows (ACS Windows) and Cisco Secure Access Control Server Solution Engine (ACS Solution Engine) 3.3.1, when the EAP-TLS protocol is enabled, does not properly handle expired or untrusted certificates, which allows remote attackers to bypass authentication and gain unauthorized access via a "cryptographically correct" certificate with valid fields such as the username.
CVE-2002-1095 1 Cisco 3 Secure Access Control Server, Vpn 3000 Concentrator Series Software, Vpn 3002 Hardware Client 2026-04-16 N/A
Cisco VPN 3000 Concentrator before 2.5.2(F), with encryption enabled, allows remote attackers to cause a denial of service (reload) via a Windows-based PPTP client with the "No Encryption" option set.
CVE-2001-0566 1 Cisco 1 Catalyst 2900 2026-04-16 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-2001-0058 1 Cisco 2 Broadband Operating System, Cisco 6xx Routers 2026-04-16 N/A
The Web interface to Cisco 600 routers running CBOS 2.4.1 and earlier allow remote attackers to cause a denial of service via a URL that does not end in a space character.
CVE-2005-3669 1 Cisco 8 Adaptive Security Appliance Software, Firewall Services Module, Ios and 5 more 2026-04-16 N/A
Multiple unspecified vulnerabilities in the Internet Key Exchange version 1 (IKEv1) implementation in multiple Cisco products allow remote attackers to cause a denial of service (device reset) via certain malformed IKE packets, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1. NOTE: due to the lack of details in the Cisco advisory, it is unclear which of CVE-2005-3666, CVE-2005-3667, and/or CVE-2005-3668 this issue applies to.
CVE-2001-0057 1 Cisco 2 Broadband Operating System, Cisco 6xx Routers 2026-04-16 N/A
Cisco 600 routers running CBOS 2.4.1 and earlier allow remote attackers to cause a denial of service via a large ICMP echo (ping) packet.
CVE-2005-2243 1 Cisco 1 Call Manager 2026-04-16 N/A
Memory leak in inetinfo.exe in Cisco CallManager (CCM) 3.2 and earlier, 3.3 before 3.3(5), 4.0 before 4.0(2a)SR2b, and 4.1 4.1 before 4.1(3)SR1, when Multi Level Admin (MLA) is enabled, allows remote attackers to cause a denial of service (memory consumption) via a large number of Admin Service Tool (AST) logins that fail.
