CVSS v3.1 |
| Cisco VPN 3000 Concentrator before 4.1.7.F allows remote attackers to determine valid groupnames by sending an IKE Aggressive Mode packet with the groupname in the ID field, which generates a response if the groupname is valid, but does not generate a response for an invalid groupname. |
| Cisco AP340 base station produces predictable TCP Initial Sequence Numbers (ISNs), which allows remote attackers to spoof or hijack TCP connections. |
| Cisco switches that support 802.1x security allow remote attackers to bypass port security and gain access to the VLAN via spoofed Cisco Discovery Protocol (CDP) messages. |
| Linux-iSCSI iSCSI implementation installs the iscsi.conf file with world-readable permissions on some operating systems, including Red Hat Linux Limbo Beta #1, which could allow local users to gain privileges by reading the cleartext CHAP password. |
| 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 VPN 5000 series concentrator hardware 6.0.21.0002 and earlier, and 5.2.23.0003 and earlier, when using RADIUS with a challenge type of Password Authentication Protocol (PAP) or Challenge, sends the user password in cleartext in a validation retry request, which could allow remote attackers to steal passwords via sniffing. |
| Cisco routers 9.17 and earlier allow remote attackers to bypass security restrictions via certain IP source routed packets that should normally be denied using the "no ip source-route" command. |
| Unknown vulnerability in Cisco Firewall Services Module (FWSM) 2.3.1 and earlier, when using URL, FTP, or HTTPS filtering exceptions, allows certain TCP packets to bypass access control lists (ACLs). |
| Heap-based buffer overflow in the TFTP server capability in Cisco IOS 11.1, 11.2, and 11.3 allows remote attackers to cause a denial of service (reset) or modify configuration via a long filename. |
| Cisco Aironet before 11.21 with Telnet enabled allows remote attackers to cause a denial of service (reboot) via a series of login attempts with invalid usernames and passwords. |
| Cisco IOS 12.2T, 12.3 and 12.3T, when processing an ISAKMP profile that specifies XAUTH authentication after Phase 1 negotiation, may not process certain attributes in the ISAKMP profile that specifies XAUTH, which allows remote attackers to bypass XAUTH and move to Phase 2 negotiations. |
| 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. |
| The command line interface (CLI) in Cisco Unified CallManager (CUCM) 5.0(1) through 5.0(3a) allows local users to overwrite arbitrary files by redirecting a command's output to a file or folder, aka bug CSCse31704. |
| Cisco IOS 12.2T, 12.3 and 12.3T, when using Easy VPN Server XAUTH version 6 authentication, allows remote attackers to bypass authentication via a "malformed packet." |
| Memory leak in the Call Telephony Integration (CTI) Framework authentication for Cisco CallManager 3.0 and 3.1 before 3.1(3) allows remote attackers to cause a denial of service (crash and reload) via a series of authentication failures, e.g. via incorrect passwords. |
| Some classic Cisco IOS devices have a vulnerability in the PPP CHAP authentication to establish unauthorized PPP connections. |
| The device driver for Intel-based gigabit network adapters in Cisco Intrusion Prevention System (IPS) 5.1(1) through 5.1(p1), as installed on various Cisco Intrusion Prevention System 42xx appliances, allows remote attackers to cause a denial of service (kernel panic and possibly network outage) via a crafted IP packet. |
| Web Cache Control Protocol (WCCP) in Cisco Cache Engine for Cisco IOS 11.2 and earlier does not use authentication, which allows remote attackers to redirect HTTP traffic to arbitrary hosts via WCCP packets to UDP port 2048. |
| The Web interface to Cisco 600 routers running CBOS 2.4.1 and earlier allow remote attackers to cause a denial of service via a URL that does not end in a space character. |
| 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. |
