| A vulnerability in Cisco IOS XE Software could allow an authenticated, local attacker to escalate their privileges to a user with root-level privileges. The vulnerability is due to insufficient validation of user-supplied content. This vulnerability could allow an attacker to load malicious software onto an affected device. | |||||
| CVE-2020-3465 | 1 Cisco | 19 1100-4p, 1100-8p, 1100 Terminal Services Gateways and 16 more | 2021-08-06 | 6.1 MEDIUM | 6.5 MEDIUM |
| A vulnerability in Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause a device to reload. The vulnerability is due to incorrect handling of certain valid, but not typical, Ethernet frames. An attacker could exploit this vulnerability by sending the Ethernet frames onto the Ethernet segment. A successful exploit could allow the attacker to cause the device to reload, resulting in a denial of service (DoS) condition. | |||||
| CVE-2021-1371 | 1 Cisco | 17 Asr 1000, Cloud Services Router 1000v, Ios Xe Sd-wan and 14 more | 2021-03-31 | 7.2 HIGH | 6.6 MEDIUM |
| A vulnerability in the role-based access control of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker with read-only privileges to obtain administrative privileges by using the console port when the device is in the default SD-WAN configuration. This vulnerability occurs because the default configuration is applied for console authentication and authorization. An attacker could exploit this vulnerability by connecting to the console port and authenticating as a read-only user. A successful exploit could allow a user with read-only permissions to access administrative privileges. | |||||
| CVE-2019-1950 | 1 Cisco | 34 Asr 1000-x, Asr 1001-hx, Asr 1002-hx and 31 more | 2020-10-19 | 7.2 HIGH | 8.4 HIGH |
| A vulnerability in Cisco IOS XE SD-WAN Software could allow an unauthenticated, local attacker to gain unauthorized access to an affected device. The vulnerability is due to the existence of default credentials within the default configuration of an affected device. An attacker who has access to an affected device could log in with elevated privileges. A successful exploit could allow the attacker to take complete control of the device. This vulnerability affects Cisco devices that are running Cisco IOS XE SD-WAN Software releases 16.11 and earlier. | |||||
| CVE-2020-3508 | 1 Cisco | 141 1000v, Asr 1000, Asr 1000-x and 138 more | 2020-10-16 | 6.1 MEDIUM | 7.4 HIGH |
| A vulnerability in the IP Address Resolution Protocol (ARP) feature of Cisco IOS XE Software for Cisco ASR 1000 Series Aggregation Services Routers with a 20-Gbps Embedded Services Processor (ESP) installed could allow an unauthenticated, adjacent attacker to cause an affected device to reload, resulting in a denial of service condition. The vulnerability is due to insufficient error handling when an affected device has reached platform limitations. An attacker could exploit this vulnerability by sending a malicious series of IP ARP messages to an affected device. A successful exploit could allow the attacker to exhaust system resources, which would eventually cause the affected device to reload. | |||||
| CVE-2020-3422 | 1 Cisco | 30 Asr 1001-hx, Asr 1001-x, Asr 1002-hx and 27 more | 2020-10-08 | 4.3 MEDIUM | 7.5 HIGH |
| A vulnerability in the IP Service Level Agreement (SLA) responder feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause the IP SLA responder to reuse an existing port, resulting in a denial of service (DoS) condition. The vulnerability exists because the IP SLA responder could consume a port that could be used by another feature. An attacker could exploit this vulnerability by sending specific IP SLA control packets to the IP SLA responder on an affected device. The control packets must include the port number that could be used by another configured feature. A successful exploit could allow the attacker to cause an in-use port to be consumed by the IP SLA responder, impacting the feature that was using the port and resulting in a DoS condition. | |||||
| CVE-2020-3421 | 1 Cisco | 24 Asr 1001-hx, Asr 1001-x, Asr 1002-hx and 21 more | 2020-10-08 | 7.1 HIGH | 7.5 HIGH |
| Multiple vulnerabilities in the Zone-Based Firewall feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause the device to reload or stop forwarding traffic through the firewall. The vulnerabilities are due to incomplete handling of Layer 4 packets through the device. An attacker could exploit these vulnerabilities by sending a certain sequence of traffic patterns through the device. A successful exploit could allow the attacker to cause the device to reload or stop forwarding traffic through the firewall, resulting in a denial of service. For more information about these vulnerabilities, see the Details section of this advisory. | |||||
| CVE-2020-3480 | 1 Cisco | 26 Asr 1001-hx, Asr 1001-x, Asr 1002-hx and 23 more | 2020-10-08 | 7.8 HIGH | 8.6 HIGH |

| CVE-2020-3524 | 1 Cisco | 26 Asr-920-10sz-pd, Asr-920-12cz-a, Asr-920-12cz-d and 23 more | 2020-10-08 | 6.9 MEDIUM | 6.8 MEDIUM |
| A vulnerability in the Cisco IOS XE ROM Monitor (ROMMON) Software for Cisco 4000 Series Integrated Services Routers, Cisco ASR 920 Series Aggregation Services Routers, Cisco ASR 1000 Series Aggregation Services Routers, and Cisco cBR-8 Converged Broadband Routers could allow an unauthenticated, physical attacker to break the chain of trust and load a compromised software image on an affected device. The vulnerability is due to the presence of a debugging configuration option in the affected software. An attacker could exploit this vulnerability by connecting to an affected device through the console, forcing the device into ROMMON mode, and writing a malicious pattern using that specific option on the device. A successful exploit could allow the attacker to break the chain of trust and load a compromised software image on the affected device. A compromised software image is any software image that has not been digitally signed by Cisco. | |||||
| CVE-2019-12664 | 1 Cisco | 4 Ios Xe, Isr 4321, Isr 4331 and 1 more | 2019-10-09 | 5.0 MEDIUM | 7.5 HIGH |
| A vulnerability in the Dialer interface feature for ISDN connections in Cisco IOS XE Software for Cisco 4000 Series Integrated Services Routers (ISRs) could allow an unauthenticated, adjacent attacker to pass IPv4 traffic through an ISDN channel prior to successful PPP authentication. The vulnerability is due to insufficient validation of the state of the PPP IP Control Protocol (IPCP). An attacker could exploit this vulnerability by making an ISDN call to an affected device and sending traffic through the ISDN channel prior to successful PPP authentication. Alternatively, an unauthenticated, remote attacker could exploit this vulnerability by sending traffic through an affected device that is configured to exit via an ISDN connection for which both the Dialer interface and the Basic Rate Interface (BRI) have been configured, but the Challenge Handshake Authentication Protocol (CHAP) password for PPP does not match the remote end. A successful exploit could allow the attacker to pass IPv4 traffic through an unauthenticated ISDN connection for a few seconds, from initial ISDN call setup until PPP authentication fails. | |||||
| CVE-2019-12646 | 1 Cisco | 13 1100-4p, 1100-8p, 1101-4p and 10 more | 2019-10-09 | 7.8 HIGH | 7.5 HIGH |
| A vulnerability in the Network Address Translation (NAT) Session Initiation Protocol (SIP) Application Layer Gateway (ALG) of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to improper processing of transient SIP packets on which NAT is performed on an affected device. An attacker could exploit this vulnerability by using UDP port 5060 to send crafted SIP packets through an affected device that is performing NAT for SIP packets. A successful exploit could allow an attacker to cause the device to reload, resulting in a denial of service (DoS) condition. | |||||
