Execution of the "show ospf interface extensive" or "show ospf interface detail" CLI commands on a Juniper Networks device running Junos OS may cause the routing protocols process (RPD) to crash and restart if OSPF interface authentication is configured, leading to a Denial of Service (DoS). By continuously executing the same CLI commands, a local attacker can repeatedly crash the RPD process causing a sustained Denial of Service. Note: Only systems utilizing ARM processors, found on the EX2300 and EX3400, are vulnerable to this issue. Systems shipped with other processor architectures are not vulnerable to this issue. The processor architecture can be displayed via the 'uname -a' command. For example: ARM (vulnerable): % uname -a | awk '{print $NF}' arm PowerPC (not vulnerable): % uname -
The following software releases have been updated to resolve this specific issue: 12.3X48-D100, 14.1X53-D140, 14.1X53-D54, 15.1R7-S7, 15.1X49-D210, 15.1X53-D593, 16.1R7-S8, 17.1R2-S12, 17.2R3-S4, 17.3R3-S8, 17.4R2-S2, 17.4R3, 18.1R3-S2, 18.2R2, 18.2X75-D40, 18.3R1-S2, 18.3R2, 18.4R1, and all subsequent releases.
Limit access to the Junos CLI and shell to only trusted administrators. Restrict access to "show ospf interface extensive" or "show ospf interface detail" via command authorization until an upgrade can be performed.
