An Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in the management daemon (mgd) process of Juniper Networks Junos OS and Junos OS Evolved allows a network-based authenticated low-privileged attacker, by executing a specific command via NETCONF, to cause a CPU Denial of Service to the device's control plane.
This issue affects:
Juniper Networks Junos OS
* All versions prior to 20.4R3-S7;
* 21.2 versions prior to 21.2R3-S5;
* 21.3 versions prior to 21.3R3-S5;
* 21.4 versions prior to 21.4R3-S4;
* 22.1 versions prior to 22.1R3-S2;
* 22.2 versions prior to 22.2R3;
* 22.3 versions prior to 22.3R2-S1, 22.3R3;
* 22.4 versions prior to 22.4R1-S2, 22.4R2.
Juniper Networks Junos OS Evolved
* All versions prior to 21.4R3-S4-EVO;
* 22.1 versions prior to 22.1R3-S2-EVO;
* 22.2 versions prior to 22.2R3-EVO;
* 22.3 versions prior to 22.3R3-EVO;
* 22.4 versions prior to 22.4R2-EVO.
An indicator of compromise can be seen by first determining if the NETCONF client is logged in and fails to log out after a reasonable period of time and secondly reviewing the WCPU percentage for the mgd process by running the following command:
mgd process example:
user@device-re#> show system processes extensive | match "mgd|PID" | except last
PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU COMMAND
92476 root 100 0 500M 89024K CPU3 3 57.5H 89.60% mgd <<<<<<<<<<< review the high cpu percentage.
Example to check for NETCONF activity:
While there is no specific command that shows a specific session in use for NETCONF, you can review logs for UI_LOG_EVENT with "client-mode 'netconf'"
For example:
mgd[38121]: UI_LOGIN_EVENT: User 'root' login, class 'super-user' [38121], ssh-connection '10.1.1.1 201 55480 10.1.1.2 22', client-mode 'netconf'

By continuously sending specially crafted BGP OPEN messages, an attacker can repeatedly crash the rpd process causing prolonged denial of service. No other Juniper Networks products or platforms are affected by this issue. Affected releases are Juniper Networks Junos OS 12.3 prior to 12.3R12-S4, 12.3R13, 12.3R3-S4; 12.3X48 prior to 12.3X48-D50; 13.3 prior to 13.3R4-S11, 13.3R10; 14.1 prior to 14.1R8-S3, 14.1R9; 14.1X53 prior to 14.1X53-D40; 14.1X55 prior to 14.1X55-D35; 14.2 prior to 14.2R4-S7, 14.2R6-S4, 14.2R7; 15.1 prior to 15.1F2-S11, 15.1F4-S1-J1, 15.1F5-S3, 15.1F6, 15.1R4; 15.1X49 prior to 15.1X49-D100; 15.1X53 prior to 15.1X53-D33, 15.1X53-D50. |
| On SRX Series devices, a crafted ICMP packet embedded within a NAT64 IPv6 to IPv4 tunnel may cause the flowd process to crash. Repeated crashes of the flowd process constitutes an extended denial of service condition for the SRX Series device. This issue only occurs if NAT64 is configured. Affected releases are Juniper Networks Junos OS 12.1X46 prior to 12.1X46-D71, 12.3X48 prior to 12.3X48-D55, 15.1X49 prior to 15.1X49-D100 on SRX Series. No other Juniper Networks products or platforms are affected by this issue. |
| Juniper Networks Junos OS on SRX series devices do not verify the HTTPS server certificate before downloading anti-virus updates. This may allow a man-in-the-middle attacker to inject bogus signatures to cause service disruptions or make the device not detect certain types of attacks. Affected Junos OS releases are: 12.1X46 prior to 12.1X46-D71; 12.3X48 prior to 12.3X48-D55; 15.1X49 prior to 15.1X49-D110; |
| A denial of service vulnerability in telnetd service on Juniper Networks Junos OS allows remote unauthenticated attackers to cause a denial of service. Affected Junos OS releases are: 12.1X46 prior to 12.1X46-D71; 12.3X48 prior to 12.3X48-D50; 14.1 prior to 14.1R8-S5, 14.1R9; 14.1X53 prior to 14.1X53-D50; 14.2 prior to 14.2R7-S9, 14.2R8; 15.1 prior to 15.1F2-S16, 15.1F5-S7, 15.1F6-S6, 15.1R5-S2, 15.1R6; 15.1X49 prior to 15.1X49-D90; 15.1X53 prior to 15.1X53-D47; 16.1 prior to 16.1R4-S1, 16.1R5; 16.2 prior to 16.2R1-S3, 16.2R2; |
| On all vSRX and SRX Series devices, when the DHCP or DHCP relay is configured, specially crafted packet might cause the flowd process to crash, halting or interrupting traffic from flowing through the device(s). Repeated crashes of the flowd process may constitute an extended denial of service condition for the device(s). If the device is configured in high-availability, the RG1+ (data-plane) will fail-over to the secondary node. If the device is configured in stand-alone, there will be temporary traffic interruption until the flowd process is restored automatically. Sustained crafted packets may cause the secondary failover node to fail back, or fail completely, potentially halting flowd on both nodes of the cluster or causing flip-flop failovers to occur. No other Juniper Networks products or platforms are affected by this issue. Affected releases are Juniper Networks Junos OS 12.1X46 prior to 12.1X46-D67 on vSRX or SRX Series; 12.3X48 prior to 12.3X48-D50 on vSRX or SRX Series; 15.1X49 prior to 15.1X49-D91, 15.1X49-D100 on vSRX or SRX Series. |
