Learn more about Junos →⚠️ Risk & Real-World Impact
Worst Case
Complete network outage as rpd crashes and restarts repeatedly, disrupting all routing functionality and causing extended downtime until patched.
Likely Case
Intermittent routing instability and service degradation as rpd memory consumption increases, leading to periodic crashes and restarts affecting network availability.
If Mitigated
Controlled impact with monitoring in place to detect memory growth and manual intervention before complete failure, but still requiring eventual patching.
🎯 Exploit Status
Exploitation requires ability to send BGP updates and trigger route attribute changes in rib sharding scenarios. No authentication needed, but requires network access to BGP peer.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Junos OS: 20.3R3-S2, 20.4R3-S6, 21.1R3, 21.2R3, 21.3R2. Junos OS Evolved: 20.4R3-S6-EVO, 21.2R3-EVO, 21.3R2-EVO.
Vendor Advisory: https://supportportal.juniper.net/JSA70608
Restart Required: Yes
Instructions:
1. Download appropriate fixed version from Juniper support portal. 2. Backup configuration. 3. Install update using 'request system software add' command. 4. Reboot device to complete installation. 5. Verify version with 'show version'.
🔧 Temporary Workarounds
Disable BGP Rib Sharding
allIf BGP rib sharding is not required, disabling it prevents the vulnerability from being triggered.
configure
delete routing-options rib-groups
commit
Enhanced Memory Monitoring
allImplement aggressive monitoring of rpd memory usage to detect and respond to leaks before crash.
show task memory
show system processes extensive | match rpd
🧯 If You Can't Patch
- Implement strict BGP peer filtering and route policy controls to limit who can send route updates
- Deploy network segmentation to isolate BGP-speaking devices and reduce attack surface
🔍 How to Verify
Check if Vulnerable:
Check current version with 'show version' and compare against affected versions. Verify BGP rib sharding configuration with 'show configuration routing-options rib-groups'.Check Version:
show versionVerify Fix Applied:
After patching, confirm version is updated with 'show version' and monitor rpd memory stability with 'show task memory' over time.📡 Detection & Monitoring
Log Indicators:
- rpd process crashes or restarts
- Memory allocation failures in system logs
- High memory usage warnings for rpd process
Network Indicators:
- BGP session instability
- Increased BGP update activity preceding crashes
- Routing table inconsistencies
SIEM Query:
process:rpd AND (event:crash OR memory_usage>threshold)
