CVSS v3.1 |
| The Authentication, Authorization, and Accounting (AAA) capability in versions 5.0(1) and 5.0(3) of the software used by multiple Cisco Anomaly Detection and Mitigation products, when running with an incomplete TACACS+ configuration without a "tacacs-server host" command, allows remote attackers to bypass authentication and gain privileges, aka Bug ID CSCsd21455. |
| Multiple SSH2 servers and clients do not properly handle large packets or large fields, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code via buffer overflow attacks, as demonstrated by the SSHredder SSH protocol test suite. |
| Unspecified vulnerability in Stack Group Bidding Protocol (SGBP) support in Cisco IOS 12.0 through 12.4 running on various Cisco products, when SGBP is enabled, allows remote attackers on the local network to cause a denial of service (device hang and network traffic loss) via a crafted UDP packet to port 9900. |
| Cross-site scripting (XSS) vulnerability in Cisco Guard DDoS Mitigation Appliance before 5.1(6), when anti-spoofing is enabled, allows remote attackers to inject arbitrary web script or HTML via certain character sequences in a URL that are not properly handled when the appliance sends a meta-refresh. |
| The internal database in Cisco Wireless Control System (WCS) for Linux and Windows before 3.2(63) stores a hard-coded username and password in plaintext within unspecified files, which allows remote authenticated users to access the database (aka bug CSCsd15951). |
| Directory traversal vulnerability in Arrowpoint (aka Cisco Content Services, or CSS) allows local unprivileged users to read arbitrary files via a .. (dot dot) attack. |
| Cisco ONS15454 and ONS15327 running ONS before 3.4 stores usernames and passwords in cleartext in the image database for the TCC, TCC+ or XTC, which could allow attackers to gain privileges by obtaining the passwords from the image database or a backup. |
| 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. |
| 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 allow remote attackers to (1) cause a denial of service (CPU and memory consumption) via a large number of open TCP connections to port 2000 and (2) cause a denial of service (fill the Windows Service Manager communication queue) via a large number of TCP connections to port 2001, 2002, or 7727. |
| Cisco IOS 12.0 and other versions can be crashed by malicious UDP packets to the syslog port. |
| Some classic Cisco IOS devices have a vulnerability in the PPP CHAP authentication to establish unauthorized PPP connections. |
| In Cisco routers under some versions of IOS 12.0 running NAT, some packets may not be filtered by input access list filters. |
| The "established" keyword in some Cisco IOS software allowed an attacker to bypass filtering. |
| Cisco 12000 with IOS 12.0 and line cards based on Engine 2 does not block non-initial packet fragments, which allows remote attackers to bypass the ACL. |
| 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. |
| Buffer overflow in Cisco 7xx routers through the telnet service. |
| 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. |
| Cisco Secure PIX Firewall 5.2(2) allows remote attackers to determine the real IP address of a target FTP server by flooding the server with PASV requests, which includes the real IP address in the response when passive mode is established. |
| Buffer overflow in CiscoSecure ACS Server 2.4(2) and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary commands via a large TACACS+ packet. |
| Cisco Personal Assistant 1.4(1) and 1.4(2) disables password authentication when "Allow Only Cisco CallManager Users" is enabled and the Corporate Directory settings refer to the directory service being used by Cisco CallManager, which allows remote attackers to gain access with a valid username. |
