TITLE

Juniper Networks Junos OS Input validation vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2018-007995

DESCRIPTION

After Junos OS device reboot or upgrade, the stateless firewall filter configuration may not take effect. This issue can be verified by running the command: user@re0> show interfaces <interface_name> extensive | match filters" CAM destination filters: 0, CAM source filters: 0 Note: when the issue occurs, it does not show the applied firewall filter. The correct output should show the applied firewall filter, for example: user@re0> show interfaces <interface_name> extensive | match filters" CAM destination filters: 0, CAM source filters: 0 Input Filters: FIREWAL_FILTER_NAME-<interface_name> This issue affects firewall filters for every address family. Affected releases are Juniper Networks Junos OS: 15.1R4, 15.1R5, 15.1R6 and SRs based on these MRs. 15.1X8 versions prior to 15.1X8.3. Juniper Junos is prone to a security-bypass vulnerability. An attacker can exploit this issue to bypass certain security restrictions and perform unauthorized actions. This may aid in further attacks. The operating system provides a secure programming interface and Junos SDK
