Impact
An unauthenticated remote attacker can execute arbitrary code as root or crash the device. They need network access to intercept or control traffic from the configured SDX/SRC server connection.
Root cause
A heap-based buffer overflow in the sdxd daemon occurs when parsing a crafted frame sent over the service-deployment TCP connection.
Affected systems
Versions not listed — check the vendor advisory.
CVSS v3.1 · CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Fix & remediation
Upgrade Junos OS and Junos OS Evolved to the patched releases referenced in advisory JSA112187. As an interim workaround, restrict or disable the SDX/SRC service deployment daemon (sdxd) connection or restrict network paths between the router and the SDX/SRC server using firewall filters.
AI-suggested. Run it in staging first and check it against the vendor advisory. Why?
