Learn more about Junos →⚠️ Risk & Real-World Impact
Worst Case
Malicious insider or compromised account causes repeated rpd crashes leading to extended network routing instability and service disruption.
Likely Case
Accidental or intentional execution of the vulnerable command by authorized users causes temporary routing daemon restart and brief network instability.
If Mitigated
With proper access controls and monitoring, impact is limited to brief service interruption during rpd restart.
🎯 Exploit Status
Exploitation requires local authenticated access with CLI privileges. No remote exploitation possible.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Junos OS: 22.4R3-S8, 23.2R2-S5, 23.4R2-S5, 24.2R2-S2, 24.4R2. Junos OS Evolved: 22.4R3-S8-EVO, 23.2R2-S5-EVO, 23.4R2-S6-EVO, 24.2R2-S2-EVO, 24.4R2-EVO.
Vendor Advisory: https://kb.juniper.net/JSA103148
Restart Required: Yes
Instructions:
1. Check current version with 'show version'. 2. Download appropriate patch from Juniper support portal. 3. Apply patch following Juniper upgrade procedures. 4. Reboot device to complete installation.
🔧 Temporary Workarounds
Restrict CLI Access
junosLimit access to 'show route' commands for low-privilege users
configure
set system login class <class-name> deny-commands "show route.*"
commit
Use Extensive Command
junosUse 'show route ... extensive' instead of 'show route ... detail' with BGP protocol options
show route <prefix> extensive
🧯 If You Can't Patch
- Implement strict role-based access control to prevent low-privilege users from executing 'show route' commands
- Monitor for rpd crashes and alert on repeated restarts of routing daemon
🔍 How to Verify
Check if Vulnerable:
Check Junos version with 'show version' and compare against affected versions listCheck Version:
show versionVerify Fix Applied:
Verify version is patched with 'show version' and test 'show route < ( receive-protocol | advertising-protocol ) bgp > detail' command📡 Detection & Monitoring
Log Indicators:
- rpd crash messages in system logs
- Routing protocol daemon restart events
- Unexpected BGP session flaps
Network Indicators:
- Increased BGP convergence times
- Routing table instability
