CVSS v3.1 |
| Cisco Secure Access Control Server (ACS) 4.x for Windows uses the client's IP address and the server's port number to grant access to an HTTP server port for an administration session, which allows remote attackers to bypass authentication via various methods, aka "ACS Weak Session Management Vulnerability." |
| Unspecified vulnerability in the SSL certificate checking functionality in Cisco CiscoWorks Management Center for IDS Sensors (IDSMC) 2.0 and 2.1, and Monitoring Center for Security (Security Monitor or Secmon) 1.1 through 2.0 and 2.1, allows remote attackers to spoof a Cisco Intrusion Detection Sensor (IDS) or Intrusion Prevention System (IPS). |
| 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. |
| Cisco IOS 11.1CC through 12.2 with Cisco Express Forwarding (CEF) enabled includes portions of previous packets in the padding of a MAC level packet when the MAC packet's length is less than the IP level packet length. |
| Cisco IP Phones 7902/7905/7912, ATA 186/188, Unity Express, ACNS, and Subscriber Edge Services Manager (SESM) allows remote attackers to cause a denial of service (crash or instability) via a compressed DNS packet with a label length byte with an incorrect offset. |
| Cisco ONS15454 optical transport platform running ONS 3.1.0 to 3.2.0 allows remote attackers to cause a denial of service (reset) by sending IP packets with non-zero Type of Service (TOS) bits to the Timing Control Card (TCC) LAN interface. |
| Cisco 12000 with IOS 12.0 and line cards based on Engine 2 does not block non-initial packet fragments, which allows remote attackers to bypass the ACL. |
| An attacker can identify a CISCO device by sending a SYN packet to port 1999, which is for the Cisco Discovery Protocol (CDP). |
| Cisco SN 5420 Storage Router 1.1(3) and earlier allows remote attackers to cause a denial of service (reboot) via a series of connections to TCP port 8023. |
| Buffer overflows in Cisco Virtual Private Network (VPN) Client 3.5.4 and earlier allows remote attackers to cause a denial of service via (1) an Internet Key Exchange (IKE) with a large Security Parameter Index (SPI) payload, or (2) an IKE packet with a large number of valid payloads. |
| Cisco Internetwork Operating System (IOS) 12.0S through 12.3T attempts to process SNMP solicited operations on improper ports (UDP 162 and a randomly chosen UDP port), which allows remote attackers to cause a denial of service (device reload and memory corruption). |
| Buffer overflow in the embedded HTTP server for Cisco Catalyst switches running CatOS 5.4 through 7.3 allows remote attackers to cause a denial of service (reset) via a long HTTP request. |
| 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." |
| Cisco IOS 12.0, 12.1, and 12.2, when GRE IP tunneling is used and the RFC2784 compliance fixes are missing, does not verify the offset field of a GRE packet during decapsulation, which leads to an integer overflow that references data from incorrect memory locations, which allows remote attackers to inject crafted packets into the routing queue, possibly bypassing intended router ACLs. |
| 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. |
| Land IP denial of service. |
| Cisco Secure PIX Firewall 5.2(2) allows remote attackers to determine the real IP address of a target FTP server by flooding the server with PASV requests, which includes the real IP address in the response when passive mode is established. |
| Extended Interior Gateway Routing Protocol (EIGRP), as implemented in Cisco IOS 11.3 through 12.2 and other products, allows remote attackers to cause a denial of service (flood) by sending a large number of spoofed EIGRP neighbor announcements, which results in an ARP storm on the local network. |
| Cisco CBOS 2.3.8 and earlier allows remote attackers to cause a denial of service via an ICMP ECHO REQUEST (ping) with the IP Record Route option set. |
| 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 an SNMPv3 message when snmp-server is set. |
