Impact
A configured BGP/EVPN peer can execute arbitrary code as root on Junos OS or crash rpd on Junos OS Evolved. The attacker needs an established BGP session with EVPN-VPWS signaling enabled to send malicious route advertisements.
Root cause
A stack-based buffer overflow in the routing protocol daemon (rpd) occurs when parsing protocol-valid route advertisements for an EVPN-VPWS service.
Affected systems
Juniper Networks Junos OS and Junos OS Evolved (versions not listed — check the vendor advisory JSA112187).
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 to the patched Junos OS/Junos OS Evolved release referenced in advisory JSA112187. If patching immediately is not possible, restrict BGP peering sessions to trusted networks or temporarily disable EVPN-VPWS route exchange with untrusted peers.
AI-suggested. Run it in staging first and check it against the vendor advisory. Why?
NVD description
A Stack-based Buffer Overflow vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a configured BGP/EVPN peer to cause root code execution on Junos OS or an rpd crash on Junos OS Evolved via protocol-valid route advertisements for an EVPN-VPWS service.
