CVE-2014-6382
HighSummary
Juniper MX Series routers running Junos versions 13.3R3 through 13.3Rx before 13.3R6, 14.1 before 14.1R4, 14.1X50 before 14.1X50-D70, and 14.2 before 14.2R2, configured as broadband edge routers, are vulnerable to remote attacks that can cause a denial of service (jpppd crash and restart) by sending a crafted PAP Authenticate-Request after the PPPoE Discovery and LCP phase are complete.
Risk Assessment
Attackers can remotely trigger a router crash, leading to service interruptions and potential financial losses for the organization.
Recommendation
It is recommended to update the router firmware to the latest versions that mitigate this vulnerability and to monitor logs for potential attack attempts.
