CVE-2017-10602: Junos OS: buffer overflow vulnerability in Junos CLI

Security readout for executives and security teams

This Junos OS flaw lets a low-privileged authenticated user with Junos CLI access potentially gain root control on affected Juniper devices. It is not an internet-routable attack by itself, but it can turn limited administrative access into full device compromise. Exposure is most likely where affected Junos OS 14.1X53, 14.2, 15.1, 15.1X49, or 15.1X53 builds remain on named EX, QFX, SRX, NFX, or QFabric platforms and untrusted or broad read-only CLI access exists. Treat this as a high-priority network infrastructure remediation if affected Juniper devices still run these legacy releases. The business risk is privilege escalation to root on core network equipment, especially where many users have CLI access. Mitigation focus: Upgrade Junos OS to the vendor-listed fixed release for the affected branch and platform.; Review Juniper JSA10803 for platform-specific remediation guidance before scheduling changes.; Limit Junos CLI access to trusted administrators until upgrades are complete..
