Buffer overflows in Cisco Virtual Private Network (VPN) Client 3.5.4 and earlier allows remote attackers to cause a denial of service via (1) an Internet Key Exchange (IKE) with a large Security Parameter Index (SPI) payload, or (2) an IKE packet with a large number of valid payloads.
CVE-2002-2052 1 Cisco 1 Ios 2025-04-03 5.0 MEDIUM N/A
Cisco 2611 router running IOS 12.1(6.5), possibly an interim release, allows remote attackers to cause a denial of service via port scans such as (1) scanning all ports on a single host and (2) scanning a network of hosts for a single open port through the router.

CVE-2006-0367 1 Cisco 1 Call Manager 2025-04-03 6.5 MEDIUM N/A
Unspecified vulnerability in Cisco CallManager 3.2 and earlier, 3.3 before 3.3(5)SR1, 4.0 before 4.0(2a)SR2c, and 4.1 before 4.1(3)SR2 allows remote authenticated users with read-only administrative privileges to obtain full administrative privileges via a "crafted URL on the CCMAdmin web page."

Denial of service in Cisco routers running NAT via a PORT command from an FTP client to a Telnet port.
CVE-2005-2025 1 Cisco 8 Vpn 3000 Concentrator, Vpn 3000 Concentrator Series Software, Vpn 3005 Concentrator Software and 5 more 2025-04-03 5.0 MEDIUM N/A
Cisco VPN 3000 Concentrator before 4.1.7.F allows remote attackers to determine valid groupnames by sending an IKE Aggressive Mode packet with the groupname in the ID field, which generates a response if the groupname is valid, but does not generate a response for an invalid groupname.
CVE-2001-0864 1 Cisco 1 12000 Router 2025-04-03 7.5 HIGH N/A
Cisco 12000 with IOS 12.0 and line cards based on Engine 2 does not properly handle the implicit "deny ip any any" rule in an outgoing ACL when the ACL contains exactly 448 entries, which can allow some outgoing packets to bypass access restrictions.
CVE-2004-1458 1 Cisco 2 Secure Access Control Server, Secure Acs Solution Engine 2025-04-03 5.0 MEDIUM N/A
The CSAdmin web administration interface for Cisco Secure Access Control Server (ACS) 3.2(2) build 15 allows remote attackers to cause a denial of service (hang) via a flood of TCP connections to port 2002.
CVE-2002-1103 1 Cisco 2 Vpn 3000 Concentrator Series Software, Vpn 3002 Hardware Client 2025-04-03 5.0 MEDIUM N/A
Cisco VPN 3000 Concentrator 2.2.x, 3.6(Rel), and 3.x before 3.5.5, allows remote attackers to cause a denial of service via (1) malformed or (2) large ISAKMP packets.
CVE-2006-4194 1 Cisco 8 Pix Firewall 501, Pix Firewall 506, Pix Firewall 515 and 5 more 2025-04-03 5.0 MEDIUM N/A
Unspecified vulnerability in Cisco PIX 500 Series Security Appliances allows remote attackers to send arbitrary UDP packets to intranet devices via unspecified vectors involving Session Initiation Protocol (SIP) fixup commands, a different issue than CVE-2006-4032. NOTE: the vendor, after working with the researcher, has been unable to reproduce the issue
CVE-2002-1189 1 Cisco 1 Unity Server 2025-04-03 4.6 MEDIUM N/A
The default configuration of Cisco Unity 2.x and 3.x does not block international operator calls in the predefined restriction tables, which could allow authenticated users to place international calls using call forwarding.
CVE-2005-1021 1 Cisco 1 Ios 2025-04-03 7.1 HIGH N/A
Memory leak in Secure Shell (SSH) in Cisco IOS 12.0 through 12.3, when authenticating against a TACACS+ server, allows remote attackers to cause a denial of service (memory consumption) via an incorrect username or password.
CVE-2001-1064 1 Cisco 1 Cbos 2025-04-03 5.0 MEDIUM N/A
Cisco 600 series routers running CBOS 2.0.1 through 2.4.2ap allows remote attackers to cause a denial of service via multiple connections to the router on the (1) HTTP or (2) telnet service, which causes the router to become unresponsive and stop forwarding packets.
CVE-2004-0589 1 Cisco 1 Ios 2025-04-03 4.3 MEDIUM N/A
Cisco IOS 11.1(x) through 11.3(x) and 12.0(x) through 12.2(x), when configured for BGP routing, allows remote attackers to cause a denial of service (device reload) via malformed BGP (1) OPEN or (2) UPDATE messages.
CVE-2005-2243 1 Cisco 1 Call Manager 2025-04-03 5.0 MEDIUM 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.
CVE-2001-0428 1 Cisco 1 Vpn 3000 Concentrator Series Software 2025-04-03 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.
CVE-2005-2244 1 Cisco 1 Call Manager 2025-04-03 5.0 MEDIUM 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.
