CVSS v3.1 |
| An attacker can identify a CISCO device by sending a SYN packet to port 1999, which is for the Cisco Discovery Protocol (CDP). |
| Buffer overflow in Cisco 7xx routers through the telnet service. |
| AAA authentication on Cisco systems allows attackers to execute commands without authorization. |
| The HTTP server in Cisco 7xx series routers 3.2 through 4.2 is enabled by default, which allows remote attackers to change the router's configuration. |
| Vulnerability in Cisco 7xx series routers allows a remote attacker to cause a system reload via a TCP connection to the router's TELNET port. |
| Cisco Catalyst LAN switches running Catalyst 5000 supervisor software allows remote attackers to perform a denial of service by forcing the supervisor module to reload. |
| In Cisco routers under some versions of IOS 12.0 running NAT, some packets may not be filtered by input access list filters. |
| Land IP denial of service. |
| Cisco IOS 12.0 and other versions can be crashed by malicious UDP packets to the syslog port. |
| Cisco PIX firewall and CBAC IP fragmentation attack results in a denial of service. |
| 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. |
| 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. |
| Some classic Cisco IOS devices have a vulnerability in the PPP CHAP authentication to establish unauthorized PPP connections. |
| In Cisco IOS 10.3, with the tacacs-ds or tacacs keyword, an extended IP access control list could bypass filtering. |
| The "established" keyword in some Cisco IOS software allowed an attacker to bypass filtering. |
| Denial of service in Cisco IOS web server allows attackers to reboot the router using a long URL. |
| A vulnerability in the VPN and management web servers of the Cisco Adaptive Security Virtual Appliance (ASAv) and Cisco Secure Firewall Threat Defense Virtual (FTDv), formerly Cisco Firepower Threat Defense Virtual, platforms could allow an unauthenticated, remote attacker to cause the virtual devices to run out of system memory, which could cause SSL VPN connection processing to slow down and eventually cease all together.
This vulnerability is due to a lack of proper memory management for new incoming SSL/TLS connections on the virtual platforms. An attacker could exploit this vulnerability by sending a large number of new incoming SSL/TLS connections to the targeted virtual platform. A successful exploit could allow the attacker to deplete system memory, resulting in a denial of service (DoS) condition. The memory could be reclaimed slowly if the attack traffic is stopped, but a manual reload may be required to restore operations quickly. |
| A vulnerability in the Cisco FXOS CLI feature on specific hardware platforms for Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to elevate their administrative privileges to root. The attacker would need valid administrative credentials on the device to exploit this vulnerability. This vulnerability exists because certain system configurations and executable files have insecure storage and permissions. An attacker could exploit this vulnerability by authenticating on the device and then performing a series of steps that includes downloading malicious system files and accessing the Cisco FXOS CLI to configure the attack. A successful exploit could allow the attacker to obtain root access on the device. |
| A security vulnerability was discovered in the local status page functionality of Cisco Meraki’s MX67 and MX68 security appliance models that may allow unauthenticated individuals to access and download logs containing sensitive, privileged device information. The vulnerability is due to improper access control to the files holding debugging and maintenance information, and is only exploitable when the local status page is enabled on the device. An attacker exploiting this vulnerability may obtain access to wireless pre-shared keys, Site-to-Site VPN key and other sensitive information. Under certain circumstances, this information may allow an attacker to obtain administrative-level access to the device. |
| A vulnerability in the Cisco Industrial Ethernet Switch Device Manager (DM) of Cisco IOS Software could allow an authenticated, remote attacker to elevate privileges.
This vulnerability is due to insufficient validation of authorizations for authenticated users. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to elevate privileges to privilege level 15.
To exploit this vulnerability, the attacker must have valid credentials for a user account with privilege level 5 or higher. Read-only DM users are assigned privilege level 5. |
