CVE-2002-2316 1 Cisco 1 Catos 2026-04-16 N/A
Cisco Catalyst 4000 series switches running CatOS 5.5.5, 6.3.5, and 7.1.2 do not always learn MAC addresses from a single initial packet, which causes unicast traffic to be broadcast across the switch and allows remote attackers to obtain sensitive network information by sniffing.
CVE-2006-4650 1 Cisco 1 Ios 2026-04-16 N/A
Cisco IOS 12.0, 12.1, and 12.2, when GRE IP tunneling is used and the RFC2784 compliance fixes are missing, does not verify the offset field of a GRE packet during decapsulation, which leads to an integer overflow that references data from incorrect memory locations, which allows remote attackers to inject crafted packets into the routing queue, possibly bypassing intended router ACLs.
CVE-2002-0954 1 Cisco 1 Pix Firewall 2026-04-16 N/A
The encryption algorithms for enable and passwd commands on Cisco PIX Firewall can be executed quickly due to a limited number of rounds, which make it easier for an attacker to decrypt the passwords using brute force techniques.

CVE-2005-2681 1 Cisco 1 Ips Sensor Software 2026-04-16 N/A
Unspecified vulnerability in the command line processing (CLI) logic in Cisco Intrusion Prevention System 5.0(1) and 5.0(2) allows local users with OPERATOR or VIEWER privileges to gain additional privileges via unknown vectors.
CVE-1999-0063 1 Cisco 1 Ios 2026-04-16 N/A
Cisco IOS 12.0 and other versions can be crashed by malicious UDP packets to the syslog port.
CVE-2000-0700 1 Cisco 4 Gigabit Switch Router 12008, Gigabit Switch Router 12012, Gigabit Switch Router 12016 and 1 more 2026-04-16 N/A
Cisco Gigabit Switch Routers (GSR) with Fast Ethernet / Gigabit Ethernet cards, from IOS versions 11.2(15)GS1A up to 11.2(19)GS0.2 and some versions of 12.0, do not properly handle line card failures, which allows remote attackers to bypass ACLs or force the interface to stop forwarding packets.
CVE-2000-0345 1 Cisco 7 Ios, Router 2500, Router 2600 and 4 more 2026-04-16 N/A
The on-line help system options in Cisco routers allows non-privileged users without "enabled" access to obtain sensitive information via the show command.
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-2025-20192 1 Cisco 1 Ios Xe Software 2026-04-15 7.7 High
A vulnerability in the Internet Key Exchange version 1 (IKEv1) implementation of Cisco IOS XE Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition. The attacker must have valid IKEv1 VPN credentials to exploit this vulnerability. This vulnerability is due to improper validation of IKEv1 phase 2 parameters before the IPsec security association creation request is handed off to the hardware cryptographic accelerator of an affected device. An attacker could exploit this vulnerability by sending crafted IKEv1 messages to the affected device. A successful exploit could allow the attacker to cause the device to reload.
CVE-2025-20339 1 Cisco 2 Sd-wan Vedge Cloud, Sd-wan Vedge Router 2026-04-15 5.8 Medium
A vulnerability in the access control list (ACL) processing of IPv4 packets of Cisco SD-WAN vEdge Software could allow an unauthenticated, remote attacker to bypass a configured ACL. This vulnerability is due to the improper enforcement of the implicit deny all at the end of a configured ACL. An attacker could exploit this vulnerability by attempting to send unauthorized traffic to an interface on an affected device. A successful exploit could allow the attacker to bypass an ACL on the affected device.
CVE-2025-20355 1 Cisco 1 Digital Network Architecture Center 2026-04-15 4.7 Medium
A vulnerability in the web-based management interface of Cisco Catalyst Center Virtual Appliance could allow an unauthenticated, remote attacker to redirect a user to a malicious web page. This vulnerability is due to improper input validation of HTTP request parameters. An attacker could exploit this vulnerability by intercepting and modifying an HTTP request from a user. A successful exploit could allow the attacker to redirect the user to a malicious web page.
CVE-2025-20361 1 Cisco 1 Unified Communications Manager 2026-04-15 4.8 Medium
A vulnerability in the web-based management interface of Cisco Unified Communications Manager (Unified CM) and Cisco Unified Communications Manager Session Management Edition (Unified CM SME) could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by injecting malicious code into specific pages of the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. To exploit this vulnerability, the attacker must have valid administrative credentials.
CVE-2024-20496 1 Cisco 2 Sd-wan Vedge Cloud, Sd-wan Vedge Router 2026-04-15 6.1 Medium
A vulnerability in the UDP packet validation code of Cisco SD-WAN vEdge Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected system. This vulnerability is due to incorrect handling of a specific type of malformed UDP packet. An attacker in a machine-in-the-middle position could exploit this vulnerability by sending crafted UDP packets to an affected device. A successful exploit could allow the attacker to cause the device to reboot, resulting in a DoS condition on the affected system.
CVE-2025-20341 1 Cisco 2 Catalyst Center, Digital Network Architecture Center 2026-04-15 8.8 High
A vulnerability in Cisco Catalyst Center Virtual Appliance could allow an authenticated, remote attacker to elevate privileges to Administrator on an affected system. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by submitting a crafted HTTP request to an affected system. A successful exploit could allow the attacker to perform unauthorized modifications to the system, including creating new user accounts or elevating their own privileges on an affected system. To exploit this vulnerability, the attacker must have valid credentials for a user account with at least the role of Observer.
