CVSS v3.1 |
| 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 ONS15454 and ONS15327 running ONS before 3.4 allows remote attackers to modify the system configuration and delete files by establishing an FTP connection to the TCC, TCC+ or XTC using a username and password that does not exist. |
| Cisco Cache Engine allows a remote attacker to gain access via a null username and password. |
| 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 Cisco VPN 5000 Client for MacOS before 5.2.2 records the most recently used login password in plaintext when saving "Default Connection" settings, which could allow local users to gain privileges. |
| Cisco Unity 2.x and 3.x uses well-known default user accounts, which could allow remote attackers to gain access and place arbitrary calls. |
| Cisco ONS15454 and ONS15327 running ONS before 3.4 have an account for the VxWorks Operating System in the TCC, TCC+ and XTC that cannot be changed or disabled, which allows remote attackers to gain privileges by connecting to the account via Telnet. |
| Multiple SSH2 servers and clients do not properly handle strings with null characters in them when the string length is specified by a length field, which could allow remote attackers to cause a denial of service or possibly execute arbitrary code due to interactions with the use of null-terminated strings as implemented using languages such as C, as demonstrated by the SSHredder SSH protocol test suite. |
| Cisco CatOS 5.x before 5.5(20) through 8.x before 8.2(2) and 8.3(2)GLX, as used in Catalyst switches, allows remote attackers to cause a denial of service (system crash and reload) by sending invalid packets instead of the final ACK portion of the three-way handshake to the (1) Telnet, (2) HTTP, or (3) SSH services, aka "TCP-ACK DoS attack." |
| Cisco IOS 12.1(3) and 12.1(3)T allows remote attackers to read and modify device configuration data via the cable-docsis read-write community string used by the Data Over Cable Service Interface Specification (DOCSIS) standard. |
| Cisco Security Monitoring, Analysis and Response System (CS-MARS) before 4.1.3 has an undocumented administrative account with a default password, which allows local users to gain privileges via the expert command. |
| 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. |
| Buffer overflow in the vpnclient program for UNIX VPN Client before 3.5.2 allows local users to gain administrative privileges via a long profile name in a connect argument. |
| Cisco Secure Access Control Server (ACS) 3.x for Windows stores ACS administrator passwords and the master key in the registry with insecure permissions, which allows local users and remote administrators to decrypt the passwords by using Microsoft's cryptographic API functions to obtain the plaintext version of the master key. |
| Cisco Content Services (CSS) switch products 11800 and earlier, aka Arrowpoint, allows local users to gain privileges by entering debug mode. |
| Cisco 340-series Aironet access point using firmware 11.01 does not use 6 of the 24 available IV bits for WEP encryption, which makes it easier for remote attackers to mount brute force attacks. |
| Cisco SN 5420 Storage Router 1.1(5) and earlier allows remote attackers to cause a denial of service (halt) via a fragmented packet to the Gigabit interface. |
| Cisco switches and routers running CBOS 2.3.8 and earlier use predictable TCP Initial Sequence Numbers (ISN), which allows remote attackers to spoof or hijack TCP connections. |
| 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 a long user name. |
| The LAN-to-LAN IPSEC capability for Cisco VPN 3000 Concentrator 2.2.x, and 3.x before 3.5.4, allows remote attackers to cause a denial of service via an incoming LAN-to-LAN connection with an existing security association with another device on the remote network, which causes the concentrator to remove the previous connection. |
