CVSS v3.1 |
| Cisco IP Phone (VoIP) 7920 1.0(8) listens to UDP port 17185 to support a VxWorks debugger, which allows remote attackers to obtain sensitive information and cause a denial of service. |
| By design, the "established" command on the Cisco PIX firewall allows connections from one host to arbitrary ports of a target host if an alternative conduit has already been allowed, which can cause administrators to configure less restrictive access controls than intended if they do not understand this functionality. |
| The Cisco Optical Service Module (OSM) for the Catalyst 6500 and 7600 series running Cisco IOS 12.1(8)E through 12.1(13.4)E allows remote attackers to cause a denial of service (hang) via a malformed packet. |
| Cisco AS5350 IOS 12.2(11)T with access control lists (ACLs) applied and possibly with ssh running allows remote attackers to cause a denial of service (crash) via a port scan, possibly due to an ssh bug. NOTE: this issue could not be reproduced by the vendor |
| Certain Cisco IOS releases in 12.2S based trains with maintenance release number 25 and later, 12.3T based trains, and 12.4 based trains reuse a Tcl Shell process across login sessions of different local users on the same terminal if the first user does not use tclquit before exiting, which may cause subsequent local users to execute unintended commands or bypass AAA command authorization checks, aka Bug ID CSCef77770. |
| Cisco CallManager (CCM) 3.2 and earlier, 3.3 before 3.3(5), 4.0 before 4.0(2a)SR2b, and 4.1 4.1 before 4.1(3)SR1 allows remote attackers to cause a denial of service (memory consumption and restart) via crafted packets to (1) the CTI Manager (ctimgr.exe) or (2) the CallManager (ccm.exe). |
| Buffer overflow in the Cisco Firewall Services Module (FWSM) in Cisco Catalyst 6500 and 7600 series devices allows remote attackers to cause a denial of service (crash and reload) via HTTP auth requests for (1) TACACS+ or (2) RADIUS authentication. |
| Cisco IOS 12.0 through 12.2, when IP routing is disabled, accepts false ICMP redirect messages, which allows remote attackers to cause a denial of service (network routing modification). |
| Cisco IOS 2.2(18)EW, 12.2(18)EWA, 12.2(14)SZ, 12.2(18)S, 12.2(18)SE, 12.2(18)SV, 12.2(18)SW, and other versions without the "no service dhcp" command, keep undeliverable DHCP packets in the queue instead of dropping them, which allows remote attackers to cause a denial of service (dropped traffic) via multiple undeliverable DHCP packets that exceed the input queue size. |
| Cisco Wireless LAN Solution Engine (WLSE) 2.0 through 2.5 and Hosting Solution Engine (HSE) 1.7 through 1.7.3 have a hardcoded username and password, which allows remote attackers to add new users, modify existing users, and change configuration. |
| Cisco devices running Application and Content Networking System (ACNS) 5.0, 5.1 before 5.1.13.7, or 5.2 before 5.2.3.9 allow remote attackers to cause a denial of service (bandwidth consumption) via "crafted IP packets" that are continuously forwarded. |
| Cisco VPN 3000 series Concentrator running firmware 4.1.7.A and earlier allows remote attackers to cause a denial of service (device reload or drop user connection) via a crafted HTTPS packet. |
| Cisco 7940/7960 Voice over IP (VoIP) phones do not properly check the Call-ID, branch, and tag values in a NOTIFY message to verify a subscription, which allows remote attackers to spoof messages such as the "Messages waiting" message. |
| Unspecified vulnerability in the VLAN Trunking Protocol (VTP) feature in Cisco IOS 12.1(22)EA3 on Catalyst 2950T switches allows remote attackers to cause a denial of service (device reboot) via a crafted Subset-Advert message packet, a different issue than CVE-2006-4774, CVE-2006-4775, and CVE-2006-4776. |
| Control cards for Cisco Optical Networking System (ONS) 15000 series nodes before 20060405 allow remote attackers to cause a denial of service (card reset) via (1) a "crafted" IP packet to a device with secure mode EMS-to-network-element access, aka bug ID CSCsc51390; (2) a "crafted" IP packet to a device with IP on the LAN interface, aka bug ID CSCsd04168; and (3) a "malformed" OSPF packet, aka bug ID CSCsc54558. |
| The internal database in Cisco Wireless Control System (WCS) for Linux and Windows before 3.2(51) uses an undocumented, hard-coded username and password, which allows remote authenticated users to read, and possibly modify, sensitive configuration data (aka bugs CSCsd15955). |
| Various Intrusion Detection Systems (IDS) including (1) Cisco Secure Intrusion Detection System, (2) Cisco Catalyst 6000 Intrusion Detection System Module, (3) Dragon Sensor 4.x, (4) Snort before 1.8.1, (5) ISS RealSecure Network Sensor 5.x and 6.x before XPU 3.2, and (6) ISS RealSecure Server Sensor 5.5 and 6.0 for Windows, allow remote attackers to evade detection of HTTP attacks via non-standard "%u" Unicode encoding of ASCII characters in the requested URL. |
| 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. |
| Cisco IP/VC Videoconferencing System 3510, 3520, 3525 and 3530 contain hard-coded default SNMP community strings, which allows remote attackers to gain access, cause a denial of service, and modify configuration. |
| The Cisco Management Center (MC) for IPS Sensors (IPS MC) 2.1 can omit port field values while generating the Cisco IOS IPS configuration file, wich can cause some signatures to be disabled and makes it easier for attackers to escape detection. |
