CVSS v3.1 |
| An attacker can identify a CISCO device by sending a SYN packet to port 1999, which is for the Cisco Discovery Protocol (CDP). |
| Cisco VPN 3000 series concentrators and Cisco VPN 3002 Hardware Client 2.x.x through 3.6.7A allow remote attackers to cause a denial of service (slowdown and possibly reload) via a flood of malformed ICMP packets. |
| Cisco DSL CPE devices running CBOS 2.4.4 and earlier allows remote attackers to cause a denial of service (hang or memory consumption) via (1) a large packet to the DHCP port, (2) a large packet to the Telnet port, or (3) a flood of large packets to the CPE, which causes the TCP/IP stack to consume large amounts of memory. |
| Cisco IOS 9.1 and earlier does not properly handle extended IP access lists when the IP route cache is enabled and the "established" keyword is set, which could allow attackers to bypass filters. |
| Buffer overflow in the authentication module for Cisco ACNS 4.x before 4.2.11, and 5.x before 5.0.5, allows remote attackers to execute arbitrary code via a long password. |
| Cisco IOS 12.2 and earlier running Cisco Discovery Protocol (CDP) allows remote attackers to cause a denial of service (memory consumption) via a flood of CDP neighbor announcements. |
| The web-based configuration interface for the Cisco ATA 186 Analog Telephone Adaptor allows remote attackers to bypass authentication via an HTTP POST request with a single byte, which allows the attackers to (1) obtain the password from the login screen, or (2) reconfigure the adaptor by modifying certain request parameters. |
| 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. |
| The design of the Hot Standby Routing Protocol (HSRP), as implemented on Cisco IOS 12.1, when using IRPAS, allows remote attackers to cause a denial of service (CPU consumption) via a router with the same IP address as the interface on which HSRP is running, which causes a loop. |
| Cisco Security Agent (CSA) 4.5 allows remote attackers to cause a denial of service (system crash) via a crafted IP packet. |
| Cisco ONS 15216 Optical Add/Drop Multiplexer (OADM) running firmware 2.2.2 and earlier allows remote attackers to cause a denial of service (management plane session loss) via crafted telnet data. |
| 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. |
| The original patch for the Cisco Content Service Switch 11000 Series authentication bypass vulnerability (CVE-2001-0622) was incomplete, which still allows remote attackers to gain additional privileges by directly requesting the web management URL instead of navigating through the interface, possibly via a variant of the original attack, as identified by Cisco bug ID CSCdw08549. |
| Unspecified vulnerability in the HTTP management interface in Cisco Unity Express (CUE) 2.2(2) and earlier, when running on any CUE Advanced Integration Module (AIM) or Network Module (NM), allows remote authenticated attackers to reset the password for any user with an expired password. |
| The web server for Cisco IP Phone (VoIP) models 7910, 7940, and 7960 allows remote attackers to cause a denial of service (reset) and possibly read sensitive memory via a large integer value in (1) the stream ID of the StreamingStatistics script, or (2) the port ID of the PortInformation script. |
| Buffer overflow in Cisco TACACS+ tac_plus server allows remote attackers to cause a denial of service via a malformed packet with a long length field. |
| 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. |
| 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. |
| Cisco VPN 3000 Concentrator 2.2.x, and 3.x before 3.5.3, adds an "HTTPS on Public Inbound (XML-Auto)(forward/in)" rule but sets the protocol to "ANY" when the XML filter configuration is enabled, which ultimately allows arbitrary traffic to pass through the concentrator. |
| Cisco VPN 3000 Concentrator 2.2.x, and 3.x before 3.5.2, allows restricted administrators to obtain certificate passwords that are stored in plaintext in the HTML source code for Certificate Management pages. |
