CVE-2026-20025 1 Cisco 2 Adaptive Security Appliance Software, Secure Firewall Threat Defense 2026-04-16 6.8 Medium
A vulnerability in the OSPF protocol of Cisco Secure Firewall ASA Software and Cisco Secure FTD Software could allow an authenticated, adjacent attacker to cause an affected device to reload unexpectedly, resulting in a DoS condition. To exploit this vulnerability, the attacker must have the OSPF secret key. This vulnerability is due to insufficient input validation when processing OSPF link-state update (LSU) packets. An attacker could exploit this vulnerability by sending crafted OSPF LSU packets. A successful exploit could allow the attacker to corrupt the heap, causing the device to reload, resulting in a DoS condition.
CVE-2026-20126 1 Cisco 1 Catalyst Sd-wan Manager 2026-04-16 8.8 High
A vulnerability in Cisco Catalyst SD-WAN Manager could allow an authenticated, local attacker with low privileges to gain root privileges on the underlying operating system. This vulnerability is due to an insufficient user authentication mechanism in the REST API. An attacker could exploit this vulnerability by sending a request to the REST API of the affected system. A successful exploit could allow the attacker to gain root privileges on the underlying operating system.
CVE-2026-20129 1 Cisco 1 Catalyst Sd-wan Manager 2026-04-16 9.8 Critical
A vulnerability in the API user authentication of Cisco Catalyst SD-WAN Manager could allow an unauthenticated, remote attacker to gain access to an affected system as a user who has the netadmin role. The vulnerability is due to improper authentication for requests that are sent to the API. An attacker could exploit this vulnerability by sending a crafted request to the API of an affected system. A successful exploit could allow the attacker to execute commands with the privileges of the netadmin role. Note: Cisco Catalyst SD-WAN Manager releases 20.18 and later are not affected by this vulnerability. 
CVE-2026-20131 1 Cisco 1 Secure Firewall Management Center 2026-04-16 10 Critical
A vulnerability in the web-based management interface of Cisco Secure Firewall Management Center (FMC) Software could allow an unauthenticated, remote attacker to execute arbitrary Java code as root on an affected device. This vulnerability is due to insecure deserialization of a user-supplied Java byte stream. An attacker could exploit this vulnerability by sending a crafted serialized Java object to the web-based management interface of an affected device. A successful exploit could allow the attacker to execute arbitrary code on the device and elevate privileges to root. Note: If the FMC management interface does not have public internet access, the attack surface that is associated with this vulnerability is reduced.
CVE-2005-1021 1 Cisco 1 Ios 2026-04-16 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-2005-1020 1 Cisco 1 Ios 2026-04-16 N/A
Secure Shell (SSH) 2 in Cisco IOS 12.0 through 12.3 allows remote attackers to cause a denial of service (device reload) (1) via a username that contains a domain name when using a TACACS+ server to authenticate, (2) when a new SSH session is in the login phase and a currently logged in user issues a send command, or (3) when IOS is logging messages and an SSH session is terminated while the server is sending data.
CVE-1999-1042 1 Cisco 1 Resource Manager 2026-04-16 N/A
Cisco Resource Manager (CRM) 1.0 and 1.1 creates world-readable log files and temporary files, which may expose sensitive information, to local users such as user IDs, passwords and SNMP community strings.
CVE-1999-0998 1 Cisco 1 Cache Engine 2026-04-16 N/A
Cisco Cache Engine allows an attacker to replace content in the cache.
CVE-1999-1000 1 Cisco 1 Cache Engine 2026-04-16 N/A
The web administration interface for Cisco Cache Engine allows remote attackers to view performance statistics.
CVE-1999-1129 1 Cisco 2 Catalyst 2900 Vlan, Ios 2026-04-16 N/A
Cisco Catalyst 2900 Virtual LAN (VLAN) switches allow remote attackers to inject 802.1q frames into another VLAN by forging the VLAN identifier in the trunking tag.
CVE-1999-0734 1 Cisco 1 Ciscosecure 2026-04-16 N/A
A default configuration of CiscoSecure Access Control Server (ACS) allows remote users to modify the server database without authentication.
CVE-1999-0453 1 Cisco 1 Router 2026-04-16 N/A
An attacker can identify a CISCO device by sending a SYN packet to port 1999, which is for the Cisco Discovery Protocol (CDP).
CVE-2004-1164 1 Cisco 1 Cns Network Registrar 2026-04-16 N/A
The lock manager in Cisco CNS Network Registrar 6.0 through 6.1.1.3 allows remote attackers to cause a denial of service (process crash) via a certain "unexpected packet sequence."
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-1999-0230 1 Cisco 1 Ios 2026-04-16 N/A
Buffer overflow in Cisco 7xx routers through the telnet service.
CVE-1999-0158 1 Cisco 1 Pix Firewall Software 2026-04-16 N/A
Cisco PIX firewall manager (PFM) on Windows NT allows attackers to connect to port 8080 on the PFM server and retrieve any file whose name and location is known.
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-2006-1672 1 Cisco 5 Ons 15310-cl Series, Ons 15454 Mspp, Ons 15600 and 2 more 2026-04-16 N/A
The installation of Cisco Transport Controller (CTC) for Cisco Optical Networking System (ONS) 15000 series nodes adds a Java policy file entry with a wildcard that grants the java.security.AllPermission permission to any http URL containing "fs/LAUNCHER.jar", which allows remote attackers to execute arbitrary code on a CTC workstation, aka bug ID CSCea25049.
CVE-1999-0445 1 Cisco 1 Ios 2026-04-16 N/A
In Cisco routers under some versions of IOS 12.0 running NAT, some packets may not be filtered by input access list filters.
CVE-1999-1100 1 Cisco 1 Pix Private Link 2026-04-16 N/A
Cisco PIX Private Link 4.1.6 and earlier does not properly process certain commands in the configuration file, which reduces the effective key length of the DES key to 48 bits instead of 56 bits, which makes it easier for an attacker to find the proper key via a brute force attack.
