CVSS v3.1 |
| OpenSSL 0.9.6k allows remote attackers to cause a denial of service (crash via large recursion) via malformed ASN.1 sequences. |
| Some classic Cisco IOS devices have a vulnerability in the PPP CHAP authentication to establish unauthorized PPP connections. |
| Cisco Catalyst 2900 Virtual LAN (VLAN) switches allow remote attackers to inject 802.1q frames into another VLAN by forging the VLAN identifier in the trunking tag. |
| Cisco 6000, 6500, and 7600 series systems with Multilayer Switch Feature Card 2 (MSFC2) and a FlexWAN or OSM module allow local users to cause a denial of service (hang or reset) by sending a layer 2 frame packet that encapsulates a layer 3 packet, but has inconsistent length values with that packet. |
| 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). |
| The on-line help system options in Cisco routers allows non-privileged users without "enabled" access to obtain sensitive information via the show command. |
| Cisco Gigabit Switch Routers (GSR) with Fast Ethernet / Gigabit Ethernet cards, from IOS versions 11.2(15)GS1A up to 11.2(19)GS0.2 and some versions of 12.0, do not properly handle line card failures, which allows remote attackers to bypass ACLs or force the interface to stop forwarding packets. |
| CBOS 2.4.1 and earlier in Cisco 600 routers allows remote attackers to cause a denial of service via a slow stream of TCP SYN packets. |
| Cisco AP340 base station produces predictable TCP Initial Sequence Numbers (ISNs), which allows remote attackers to spoof or hijack TCP connections. |
| Cisco VPN 3000 series concentrators before 2.5.2(F) allow remote attackers to cause a denial of service via an IP packet with an invalid IP option. |
| 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. |
| The default installation of Cisco voice products, when running the IBM Director Agent on IBM servers before OS 2000.2.6, does not require authentication, which allows remote attackers to gain administrator privileges by connecting to TCP port 14247. |
| Cisco IOS 12.0(5)XU through 12.1(2) allows remote attackers to read system administration and topology information via an "snmp-server host" command, which creates a readable "community" community string if one has not been previously created. |
| The VLAN Trunking Protocol (VTP) feature in Cisco IOS 12.1(19) and CatOS allows remote attackers to cause a denial of service by sending a VTP update with a revision value of 0x7FFFFFFF, which is incremented to 0x80000000 and is interpreted as a negative number in a signed context. |
| Cross-site scripting (XSS) vulnerability in Cisco CallManager 3.3 before 3.3(5)SR3, 4.1 before 4.1(3)SR4, 4.2 before 4.2(3), and 4.3 before 4.3(1), allows remote attackers to inject arbitrary web script or HTML via the (1) pattern parameter in ccmadmin/phonelist.asp and (2) arbitrary parameters in ccmuser/logon.asp, aka bugid CSCsb68657. |
| The transparent proxy feature of the Cisco Application Velocity System (AVS) 3110 5.0 and 4.0 and earlier, and 3120 5.0.0 and earlier, has a default configuration that allows remote attackers to proxy arbitrary TCP connections, aka Bug ID CSCsd32143. |
| 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 does not quickly time out Realtime Information Server Data Collection (RISDC) sockets, which results in a "resource leak" that allows remote attackers to cause a denial of service (memory and connection consumption) in RisDC.exe. |
| 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. |
| 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). |
| Cisco IOS 11.x and 12.0 through 12.2 allows remote attackers to cause a denial of service (traffic block) by sending a particular sequence of IPv4 packets to an interface on the device, causing the input queue on that interface to be marked as full. |
