An Incorrect Permission Assignment for Critical Resource vulnerability in the On-Box Anomaly detection framework of Juniper Networks Junos OS Evolved on PTX Series allows an unauthenticated, network-based attacker to execute code as root.

The On-Box Anomaly detection framework should only be reachable by other internal processes over the internal routing instance, but not over an externally exposed port. With the ability to access and manipulate the service to execute code as root a remote attacker can take complete control of the device. Please note that this service is enabled by default as no specific configuration is required.

This issue affects Junos OS Evolved on PTX Series:

25.4 versions before 25.4R1-S1-EVO, 25.4R2-EVO.

This issue does not affect Junos OS Evolved versions before 25.4R1-EVO.

This issue does not affect Junos OS.

An OS Command Injection vulnerability in TACACS of Juniper Networks Junos OS Evolved allows a low-privileged TACACS+-authenticated user to execute commands with root privileges when periodic TACACS+ authorization-refresh is enabled.

A Heap-based Buffer Overflow vulnerability in the sdxd service-deployment daemon of Juniper Networks Junos OS and Junos OS Evolved allows a remote unauthenticated attacker who can control or intercept the configured SDX/SRC server connection to execute code as root or cause denial of service via a crafted frame received over the service-deployment TCP connection.

A Stack-based Buffer Overflow vulnerability in the BGP routing daemon of Juniper Networks Junos OS and Junos OS Evolved allows a configured BGP flowspec peer to cause routing-engine compromise or a routing-daemon denial of service via flowspec route re-advertisement when BGP update-threading is enabled.

A Stack-based Buffer Overflow vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a configured external BGP neighbor to execute arbitrary commands with root privileges via BMP route monitoring.

A Stack-based Buffer Overflow vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a configured BGP/EVPN peer to cause root code execution on Junos OS or an rpd crash on Junos OS Evolved via protocol-valid route advertisements for an EVPN-VPWS service.

A Stack-based Buffer Overflow vulnerability in the httpd process of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated network attacker to cause remote code execution and denial of service via a J-Web virtual-domain configured.

An Improper Authentication vulnerability in the J-Web management interface and its NETCONF session handling of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated network attacker to obtain root-level device configuration access and take over the device via a reachable J-Web HTTP or HTTPS service when web management is enabled.

A Stack-based Buffer Overflow vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated BGP peer to cause a denial of service and potential root-level command execution via crafted BGP route updates when the BGP Monitoring Protocol (BMP) is enabled.

A Use of Externally-Controlled Format String vulnerability in the jti-dialoutd of Juniper Networks Junos OS Evolved allows an authenticated network attacker to cause persistent telemetry dial-out denial of service via a crafted analytics sensor resource submitted through gNMI listener.

An Improper Handling of Values vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS Evolved on ACX 7000 Series allows a network-based, unauthenticated attacker to cause a Denial-of-Service (DoS).

If a value is configured for DDoS bandwidth or burst parameters for any protocol in a queue, all protocols which share the same queue will have their bandwidth or burst value changed to the new value. If, for example, OSPF was configured with a certain bandwidth value, ISIS would also be limited to this value. So inadvertently either the control plane is open for a high level of specific traffic which was supposed to be limited to a lower value, or the limit for a certain protocol is so low that chances to succeed with a volumetric DoS attack are significantly increased.

This issue affects Junos OS Evolved on ACX 7000 Series:

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).

In specific cases the state of TCP sessions that are terminated is not cleared, which over time leads to an exhaustion of resources, preventing new connections to the control plane from being established.

A continuously increasing number of connections shown by:

user@host > show system connections

is indicative of the problem. To recover the respective RE needs to be restarted manually.

This issue only affects IPv4 but does not affect IPv6. This issue only affects TCP sessions established in-band (over an interface on an FPC) but not out-of-band (over the management ethernet port on the routing-engine).

This issue affects Junos OS Evolved:

All versions before 21.4R3-S9-EVO, 22.2 versions before 22.2R3-S4-EVO, 22.4 version before 22.4R3-S3-EVO, 23.2 versions before 23.2R2-S1-EVO, 23.4 versions before 23.4R2-EVO.

A Missing Release of Memory after Effective Lifetime vulnerability in the Juniper Tunnel Driver (jtd) of Juniper Networks Junos OS Evolved allows an unauthenticated network-based attacker to cause Denial of Service.

Receipt of specifically malformed IPv6 packets, destined to the device, causes kernel memory to not be freed, resulting in memory exhaustion leading to a system crash and Denial of Service (DoS). Continuous receipt and processing of these packets will continue to exhaust kernel memory, creating a sustained Denial of Service (DoS) condition. This issue only affects systems configured with IPv6.

This issue affects Junos OS Evolved:

from 22.4-EVO before 22.4R3-S5-EVO,  from 23.2-EVO before 23.2R2-S2-EVO,  from 23.4-EVO before 23.4R2-S2-EVO,  from 24.2-EVO before 24.2R1-S2-EVO, 24.2R2-EVO.

This issue does not affect Juniper Networks Junos OS Evolved versions prior to 22.4R1-EVO.

This is a similar, but different vulnerability than the issue reported as CVE-2024-39549.

A double-free vulnerability in the routing process daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an attacker to send a malformed BGP Path attribute update which allocates memory used to log the bad path attribute. This double free of memory is causing an rpd crash, leading to a Denial of Service (DoS).

This issue affects:

Junos OS:  from 22.4 before 22.4R3-S4.

Junos OS Evolved: from 22.4 before 22.4R3-S4-EVO.

A Buffer Access with Incorrect Length Value 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 attacker sends a specific ICMPv6 packet to an interface with "protocols router-advertisement" configured, rpd crashes and restarts. Continued receipt of this packet will cause a sustained DoS condition.

This issue only affects systems configured with IPv6.

This issue affects Junos OS:

All versions before 21.2R3-S9,  from 21.4 before 21.4R3-S10, from 22.2 before 22.2R3-S6, from 22.4 before 22.4R3-S4, from 23.2 before 23.2R2-S2, from 23.4 before 23.4R2;

This is a more complete fix for previously published CVE-2024-39549 (JSA83011).

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

A Buffer Over-read 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 device receives a BGP update with a set of specific optional transitive attributes over an established peering session, rpd will crash and restart when attempting to advertise the received information to another peer. This issue can only happen if one or both of the BGP peers of the receiving session are non-4-byte-AS capable as determined from the advertised capabilities during BGP session establishment. Junos OS and Junos OS Evolved default behavior is 4-byte-AS capable unless this has been specifically disabled by configuring:

[ protocols bgp ... disable-4byte-as ]

Established BGP sessions can be checked by executing:

show bgp neighbor <IP address> | match "4 byte AS"
