CVSS v3.1 |
| Multiple instances of an Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
vulnerability in the CLI of Juniper Networks Junos OS Evolved could be used to elevate privileges and/or execute unauthorized commands.
When an attacker executes crafted CLI commands, the options are processed via a script in some cases. These scripts are not hardened so injected commands might be executed via the shell, which allows an attacker to perform operations, which they should not be able to do according to their assigned permissions.
This issue affects Junos OS Evolved:
* 24.2 versions before 24.2R2-S2-EVO,
* 24.4 versions before 24.4R2-EVO.
This issue does not affect Junos OS Evolved versions earlier than 24.2R1-EVO. |
| An Improper Check for Unusual or Exceptional Conditions vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial-Of-Service (DoS).
When an affected system receives a specific BGP EVPN update message over an established BGP session, this causes an rpd crash and restart.
A BGP EVPN configuration is not necessary to be vulnerable. If peers are not configured to send BGP EVPN updates to a vulnerable device, then this issue can't occur.
This issue affects iBGP and eBGP, over IPv4 and IPv6.
This issue affects:
Junos OS:
* 23.4 versions from
23.4R2-S3 before 23.4R2-S5,
* 24.2 versions from
24.2R2
before 24.2R2-S1,
* 24.4 versions before 24.4R1-S3, 24.4R2;
Junos OS Evolved:
* 23.4-EVO versions from 23.4R2-S2-EVO before 23.4R2-S5-EVO,
* 24.2-EVO versions from 24.2R2-EVO before 24.2R2-S1-EVO,
* 24.4-EVO versions before 24.4R1-S3-EVO, 24.4R2-EVO. |
| A Use of Uninitialized Resource vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on SRX4700 devices allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS).
When forwarding-options sampling is enabled, receipt of any traffic destined to the Routing Engine (RE) by the PFE line card leads to an FPC crash and restart, resulting in a Denial of Service (DoS).
Continued receipt and processing of any traffic leading to the RE by the PFE line card will create a sustained Denial of Service (DoS) condition to the PFE line card.
This issue affects Junos OS on SRX4700:
* from 24.4 before 24.4R1-S3, 24.4R2
This issue affects IPv4 and IPv6. |
| An Access of Uninitialized Pointer vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved with BGP sharding configured allows an attacker triggering indirect next-hop updates, along with timing outside the attacker's control, to cause rpd to crash and restart, leading to a Denial of Service (DoS).
With BGP sharding enabled, triggering route resolution of an indirect next-hop (e.g., an IGP route change over which a BGP route gets resolved), may cause rpd to crash and restart. An attacker causing continuous IGP route churn, resulting in repeated route re-resolution, will increase the likelihood of triggering this issue, leading to a potentially extended DoS condition.
This issue affects:
Junos OS:
* all versions before 21.4R3-S6,
* from 22.1 before 22.1R3-S6,
* from 22.2 before 22.2R3-S3,
* from 22.3 before 22.3R3-S3,
* from 22.4 before 22.4R3,
* from 23.2 before 23.2R2;
Junos OS Evolved:
* all versions before 22.3R3-S3-EVO,
* from 22.4 before 22.4R3-EVO,
* from 23.2 before 23.2R2-EVO.
Versions before Junos OS 21.3R1 and Junos OS Evolved 21.3R1-EVO are unaffected by this issue. |
| A password aging vulnerability in the RADIUS client of Juniper Networks Junos OS and Junos OS Evolved allows an authenticated, network-based attacker to access the device without enforcing the required password change.
Affected devices allow logins by users for whom the RADIUS server has responded with a reject and required the user to change the password as their password was expired. Therefore the policy mandating the password change is not enforced.
This does not allow users to login with a wrong password, but only with the correct but expired one.
This issue affects:
Junos OS:
* all versions before 22.4R3-S8,
* 23.2 versions before 23.2R2-S4,
* 23.4 versions before 23.4R2-S5,
* 24.2 versions before 24.2R2-S1,
* 24.4 versions before 24.4R1-S3, 24.4R2;
Junos OS Evolved:
* all versions before 22.4R3-S8-EVO,
* 23.2 versions before 23.2R2-S4-EVO,
* 23.4 versions before 23.4R2-S5-EVO,
* 24.2 versions before 24.2R2-S1-EVO,
* 24.4 versions before 24.4R1-S3-EVO, 24.4R2-EVO. |
| A NULL Pointer Dereference vulnerability in the PFE management daemon (evo-pfemand) of Juniper Networks Junos OS Evolved on ACX7024, ACX7024X, ACX7100-32C, ACX7100-48L, ACX7348, ACX7509 devices allows an unauthenticated, adjacent attacker to cause a
Denial-of-Service (DoS).
Whenever specific valid multicast traffic is received on any layer 3 interface the evo-pfemand process crashes and restarts.
Continued receipt of specific valid multicast traffic results in a sustained Denial of Service (DoS) attack.
This issue affects Junos OS Evolved on ACX7024, ACX7024X, ACX7100-32C, ACX7100-48L, ACX7348, ACX7509:
* from 23.2R2-EVO before 23.2R2-S4-EVO,
* from 23.4R1-EVO before 23.4R2-EVO.
This issue affects IPv4 and IPv6.
This issue does not affect Junos OS Evolved ACX7024, ACX7024X, ACX7100-32C, ACX7100-48L, ACX7348, ACX7509 versions before 23.2R2-EVO. |
| An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS Evolved on PTX Series allows an unauthenticated, network-based attacker to cause impact to confidentiality and availability.
When an output firewall filter is configured with one or more terms where the action is 'reject', packets matching these terms are erroneously sent to the Routing Engine (RE) and further processed there. Processing of these packets will consume limited RE resources. Also responses from the RE back to the source of this traffic could reveal confidential information about the affected device.
This issue only applies to firewall filters applied to WAN or revenue interfaces, so not the mgmt or lo0 interface of the routing-engine, nor any input filters.
This issue affects Junos OS Evolved on PTX Series:
* all versions before 22.4R3-EVO,
* 23.2 versions before 23.2R2-EVO. |
| An Origin Validation Error vulnerability in an insufficient protected file of Juniper Networks Junos OS on EX4600 Series and QFX5000 Series allows an unauthenticated attacker with physical access to the device to create a backdoor which allows complete control of the system.
When a device isn't configured with a root password, an attacker can modify a specific file. It's contents will be added to the Junos configuration of the device without being visible. This allows for the addition of any configuration unknown
to the actual operator, which includes users, IP addresses and other configuration which could allow unauthorized access to the device.
This exploit is persistent across reboots and even zeroization.
The indicator of compromise is a modified /etc/config/<platform>-defaults[-flex].conf file. Review that file for unexpected configuration statements, or compare it to an unmodified version which can be extracted from the original Juniper software image file. For details on the extraction procedure please contact Juniper Technical Assistance Center (JTAC).
To restore the device to a trusted initial configuration the system needs to be reinstalled from physical media.
This issue affects Junos OS on EX4600 Series and QFX5000 Series:
* All versions before 21.4R3,
* 22.2 versions before 22.2R3-S3. |
| An Uncontrolled Resource Consumption vulnerability in the Connectivity Fault Management (CFM) daemon and the Connectivity Fault Management Manager (cfmman) of Juniper Networks Junos OS Evolved on PTX10001-36MR, PTX10002-36QDD, PTX10004, PTX10008, PTX10016 allows an unauthenticated, adjacent attacker to cause a Denial-of-Service (DoS).
An attacker on an adjacent device sending specific valid traffic can cause cfmd to spike the CPU to 100% and cfmman's memory to leak, eventually to cause the FPC crash and restart.
Continued receipt and processes of these specific valid packets will sustain the Denial of Service (DoS) condition.
An indicator of compromise is to watch for an increase in cfmman memory rising over time by issuing the following command and evaluating the RSS number. If the RSS is growing into GBs then consider restarting the device to temporarily clear memory.
user@device> show system processes node fpc<num> detail | match cfmman
Example:
show system processes node fpc0 detail | match cfmman
F S UID PID PPID PGID SID C PRI NI ADDR SZ WCHAN RSS PSR STIME TTY TIME CMD
4 S root 15204 1 15204 15204 0 80 0 - 90802 - 113652 4 Sep25 ? 00:15:28 /usr/bin/cfmman -p /var/pfe -o -c /usr/conf/cfmman-cfg-active.xml
This issue affects Junos OS Evolved on PTX10001-36MR, PTX10002-36QDD, PTX10004, PTX10008, PTX10016:
* from 23.2R1-EVO before 23.2R2-S4-EVO,
* from 23.4 before 23.4R2-S4-EVO,
* from 24.2 before 24.2R2-EVO,
* from 24.4 before 24.4R1-S2-EVO, 24.4R2-EVO.
This issue does not affect Junos OS Evolved on PTX10001-36MR, PTX10002-36QDD, PTX10004, PTX10008, PTX10016 before 23.2R1-EVO. |
| A Buffer Copy without Checking Size of Input vulnerability in the
Session Initialization Protocol (SIP) ALG of Juniper Networks Junos OS on MX Series and SRX Series allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS).
When memory utilization is high, and specific SIP packets are received, flowd crashes. While the system recovers automatically, the disruption can significantly impact service stability. Continuous receipt of these specific SIP packets, while high utilization is present, will cause a sustained DoS condition. The utilization is outside the attackers control, so they would not be able to deterministically exploit this.
This issue affects Junos OS on SRX Series and MX Series:
* All versions before 22.4R3-S7,
* from 23.2 before 23.2R2-S4,
* from 23.4 before 23.4R2-S5,
* from 24.2 before 24.2R2. |
| A Missing Authorization vulnerability in the Socket Intercept (SI) command file interface of Juniper Networks Junos OS Evolved allows an authenticated, low-privilege local attacker to modify certain files, allowing the attacker to cause any command to execute with root privileges leading to privilege escalation ultimately compromising the system.
This issue affects Junos OS Evolved:
* All versions prior to 21.2R3-S8-EVO,
* 21.4 versions prior to 21.4R3-S6-EVO,
* 22.1 versions prior to 22.1R3-S5-EVO,
* 22.2 versions prior to 22.2R3-S3-EVO,
* 22.3 versions prior to 22.3R3-S3-EVO,
* 22.4 versions prior to 22.4R3-EVO,
* 23.2 versions prior to 23.2R2-EVO. |
| An Improper Validation of Syntactic Correctness of Input vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on MX Series with MPC10/11 or LC9600, MX304, and Junos OS Evolved on ACX Series and PTX Series allows an unauthenticated, network based attacker to cause a Denial-of-Service (DoS).
This issue can occur in two scenarios:
1. If a device, which is configured with SFLOW and ECMP, receives specific valid transit traffic, which is subject to sampling, the packetio process crashes, which in turn leads to an evo-aftman crash and causes the FPC to stop working until it is restarted. (This scenario is only applicable to PTX but not to ACX or MX.)
2. If a device receives a malformed CFM packet on an interface configured with CFM, the packetio process crashes, which in turn leads to an evo-aftman crash and causes the FPC to stop working until it is restarted. Please note that the CVSS score is for the formally more severe issue 1.
The CVSS score for scenario 2. is: 6.5 (CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
This issue affects Junos OS:
* All versions before 21.2R3-S4,
* 21.4 versions before 21.4R2,
* 22.2 versions before 22.2R3-S2;
Junos OS Evolved:
* All versions before 21.2R3-S8-EVO,
* 21.4 versions before 21.4R2-EVO. |

An Allocation of Resources Without Limits or Throttling vulnerability in the kernel of Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS).
If a high rate of specific valid packets are processed by the routing engine (RE) this will lead to a loss of connectivity of the RE with other components of the chassis and thereby a complete and persistent system outage. Please note that a carefully designed lo0 firewall filter will block or limit these packets which should prevent this issue from occurring.
The following log messages can be seen when this issue occurs:
<host> kernel: nf_conntrack: nf_conntrack: table full, dropping packet
This issue affects Juniper Networks Junos OS Evolved:
* All versions earlier than 20.4R3-S7-EVO;
* 21.2R1-EVO and later versions;
* 21.4-EVO versions earlier than 21.4R3-S5-EVO;

| An Improper Validation of Syntactic Correctness of Input vulnerability in the kernel of Juniper Networks Junos OS Evolved on PTX series allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS). When an incoming TCP packet destined to the device is malformed there is a possibility of a kernel panic. Only TCP packets destined to the ports for BGP, LDP and MSDP can trigger this. This issue only affects PTX10004, PTX10008, PTX10016. No other PTX Series devices or other platforms are affected. This issue affects Juniper Networks Junos OS Evolved: 20.4-EVO versions prior to 20.4R3-S4-EVO; 21.3-EVO versions prior to 21.3R3-EVO; 21.4-EVO versions prior to 21.4R3-EVO; 22.1-EVO versions prior to 22.1R2-EVO. This issue does not affect Juniper Networks Junos OS Evolved versions prior to 20.4R1-EVO. |
| A Use After Free vulnerability in the Routing Protocol Daemon (rdp) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated network-based attacker to cause Denial of Service (DoS). When a BGP session flap happens, a Use After Free of a memory location that was assigned to another object can occur, which will lead to an rpd crash. This is a race condition that is outside of the attacker's control and cannot be deterministically exploited. Continued flapping of BGP sessions can create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks Junos OS: All versions prior to 18.4R2-S9, 18.4R3-S11; 19.1 versions prior to 19.1R3-S8; 19.2 version 19.2R1 and later versions; 19.3 versions prior to 19.3R3-S5; 19.4 versions prior to 19.4R2-S6, 19.4R3-S6; 20.1 version 20.1R1 and later versions; 20.2 versions prior to 20.2R3-S3; 20.3 versions prior to 20.3R3-S2; 20.4 versions prior to 20.4R3-S1; 21.1 versions prior to 21.1R3-S3; 21.2 versions prior to 21.2R2-S1, 21.2R3.
