CVE-2020-1660
TITLE
Juniper Networks Junos MX Run on the series Junos OS Vulnerability in
Trust: 0.8
DESCRIPTION
When DNS filtering is enabled on Juniper Networks Junos MX Series with one of the following cards MS-PIC, MS-MIC or MS-MPC, an incoming stream of packets processed by the Multiservices PIC Management Daemon (mspmand) process, responsible for managing "URL Filtering service", may crash, causing the Services PIC to restart. While the Services PIC is restarting, all PIC services including DNS filtering service (DNS sink holing) will be bypassed until the Services PIC completes its boot process. This vulnerability might allow an attacker to cause an extended Denial of Service (DoS) attack against the device and to cause clients to be vulnerable to DNS based attacks by malicious DNS servers when they send DNS requests through the device. As a result, devices which were once protected by the DNS Filtering service are no longer protected and at risk of exploitation. This issue affects Juniper Networks Junos OS: 17.3 versions prior to 17.3R3-S8; 18.3 versions prior to 18.3R3-S1; 18.4 versions prior to 18.4R3; 19.1 versions prior to 19.1R3; 19.2 versions prior to 19.2R2; 19.3 versions prior to 19.3R3. This issue does not affect Juniper Networks Junos OS 17.4, 18.1, and 18.2. Juniper Networks Junos MX Run on the series Junos OS Contains an unspecified vulnerability.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. The operating system provides a secure programming interface and Junos SDK. A security vulnerability exists in Junos OS MX that could be exploited by an attacker to trigger a fatal error through DNS filtering to trigger a denial of service
