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'

| On Juniper Networks EX Series Ethernet Switches running affected Junos OS versions, a vulnerability in IPv6 processing has been discovered that may allow a specially crafted IPv6 Neighbor Discovery (ND) packet destined to an EX Series Ethernet Switch to cause a slow memory leak. A malicious network-based packet flood of these crafted IPv6 NDP packets may eventually lead to resource exhaustion and a denial of service. The affected Junos OS versions are: 12.3 prior to 12.3R12-S4, 12.3R13; 13.3 prior to 13.3R10; 14.1 prior to 14.1R8-S3, 14.1R9; 14.1X53 prior ro 14.1X53-D12, 14.1X53-D40; 14.1X55 prior to 14.1X55-D35; 14.2 prior to 14.2R6-S4, 14.2R7-S6, 14.2R8; 15.1 prior to 15.1R5; 16.1 before 16.1R3; 16.2 before 16.2R1-S3, 16.2R2. 17.1R1 and all subsequent releases have a resolution for this vulnerability. |
| A vulnerability in Juniper Networks NorthStar Controller Application prior to version 2.1.0 Service Pack 1 may allow an unauthenticated, unprivileged, network-based attacker to cause various denials of services leading to targeted information disclosure, modification of any component of the NorthStar system, including managed systems, and full denial of services to any systems under management which NorthStar interacts with using read-only or read-write credentials. |
| J-Web does not validate certain input that may lead to cross-site request forgery (CSRF) issues or cause a denial of J-Web service (DoS). |
| 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. |
| A vulnerability in Juniper Networks NorthStar Controller Application prior to version 2.1.0 Service Pack 1 may allow an unauthenticated, unprivileged, network-based attacker to cause various system services partial to full denials of services, modification of system states and files, and potential disclosure of sensitive information which may assist the attacker in further attacks on the system through the use of multiple attack vectors, including man-in-the-middle attacks, file injections, and malicious execution of commands causing out of bound memory conditions leading to other attacks. |
| On Juniper Networks products or platforms running Junos OS 11.4 prior to 11.4R13-S3, 12.1X46 prior to 12.1X46-D60, 12.3 prior to 12.3R12-S2 or 12.3R13, 12.3X48 prior to 12.3X48-D40, 13.2X51 prior to 13.2X51-D40, 13.3 prior to 13.3R10, 14.1 prior to 14.1R8, 14.1X53 prior to 14.1X53-D12 or 14.1X53-D35, 14.1X55 prior to 14.1X55-D35, 14.2 prior to 14.2R7, 15.1 prior to 15.1F6 or 15.1R3, 15.1X49 prior to 15.1X49-D60, 15.1X53 prior to 15.1X53-D30 and DHCPv6 enabled, when a crafted DHCPv6 packet is received from a subscriber, jdhcpd daemon crashes and restarts. Repeated crashes of the jdhcpd process may constitute an extended denial of service condition for subscribers attempting to obtain IPv6 addresses. |
| On Juniper Networks Junos Space versions prior to 16.1R1, due to an insufficient authorization check, readonly users on the Junos Space administrative web interface can create privileged users, allowing privilege escalation. |
| Any Juniper Networks SRX series device with one or more ALGs enabled may experience a flowd crash when traffic is processed by the Sun/MS-RPC ALGs. This vulnerability in the Sun/MS-RPC ALG services component of Junos OS allows an attacker to cause a repeated denial of service against the target. Repeated traffic in a cluster may cause repeated flip-flop failure operations or full failure to the flowd daemon halting traffic on all nodes. Only IPv6 traffic is affected by this issue. IPv4 traffic is unaffected. This issues is not seen with to-host traffic. This issue has no relation with HA services themselves, only the ALG service. 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-D55 on SRX; 12.1X47 prior to 12.1X47-D45 on SRX; 12.3X48 prior to 12.3X48-D32, 12.3X48-D35 on SRX; 15.1X49 prior to 15.1X49-D60 on SRX. |
| Insufficient authentication vulnerability in Junos Space before 15.2R2 allows remote network based users with access to Junos Space web interface to perform certain administrative tasks without authentication. |
| By flooding a Juniper Networks router running Junos OS with specially crafted IPv6 traffic, all available resources can be consumed, leading to the inability to store next hop information for legitimate traffic. In extreme cases, the crafted IPv6 traffic may result in a total resource exhaustion and kernel panic. The issue is triggered by traffic destined to the router. Transit traffic does not trigger the vulnerability. This issue only affects devices with IPv6 enabled and configured. Devices not configured to process IPv6 traffic are unaffected by this vulnerability. This issue was found during internal product security testing. Juniper SIRT is not aware of any malicious exploitation of this vulnerability. Affected releases are Juniper Networks Junos OS 11.4 prior to 11.4R13-S3; 12.3 prior to 12.3R3-S4; 12.3X48 prior to 12.3X48-D30; 13.3 prior to 13.3R10, 13.3R4-S11; 14.1 prior to 14.1R2-S8, 14.1R4-S12, 14.1R8; 14.1X53 prior to 14.1X53-D28, 14.1X53-D40; 14.1X55 prior to 14.1X55-D35; 14.2 prior to 14.2R3-S10, 14.2R4-S7, 14.2R6; 15.1 prior to 15.1F2-S5, 15.1F5-S2, 15.1F6, 15.1R3; 15.1X49 prior to 15.1X49-D40; 15.1X53 prior to 15.1X53-D57, 15.1X53-D70. |
| An incorrect permissions vulnerability in Juniper Networks Junos OS on vMX may allow local unprivileged users on a host system read access to vMX or vPFE images and obtain sensitive information contained in them such as private cryptographic keys. This issue was found during internal product security testing. Juniper SIRT is not aware of any malicious exploitation of this vulnerability. No other Juniper Networks products or platforms are affected by this issue. Affected releases are Juniper Networks Junos OS 15.1 prior to 15.1F5; 14.1 prior to 14.1R8 |
| An insufficient authentication vulnerability in Juniper Networks NorthStar Controller Application prior to version 2.1.0 Service Pack 1 may allow a malicious, network based, unauthenticated attacker to perform privileged actions to gain complete control over the environment. |
| A persistent cross site scripting vulnerability in NetScreen WebUI of Juniper Networks Juniper NetScreen Firewall+VPN running ScreenOS allows a user with the 'security' role to inject HTML/JavaScript content into the management session of other users including the administrator. This enables the lower-privileged user to effectively execute commands with the permissions of an administrator. This issue affects Juniper Networks ScreenOS 6.3.0 releases prior to 6.3.0r24 on SSG Series. No other Juniper Networks products or platforms are affected by this issue. |
| An insufficient authentication vulnerability in Juniper Networks NorthStar Controller Application prior to version 2.1.0 Service Pack 1 may allow an unprivileged, authenticated, user to execute certain specific unprivileged system files capable of causing widespread denials of system services. |
| A denial of service vulnerability in Juniper Networks NorthStar Controller Application prior to version 2.1.0 Service Pack 1 may allow an unauthenticated, local user, to create a fork bomb scenario, also known as a rabbit virus, or wabbit, which will create processes that replicate themselves, until all resources are consumed on the system, leading to a denial of service to the entire system until it is restarted. Continued attacks by an unauthenticated, local user, can lead to persistent denials of services. |
