CVE-2025-60011 is a medium severity vulnerability in Juniper Networks Junos OS and Junos OS Evolved affecting the routing protocol daemon (rpd). An unauthenticated, network-based attacker can send a crafted optional, transitive BGP attribute that is improperly checked and modified by the affected device before propagation. This causes peers to detect malformed attributes and likely terminate BGP sessions, resulting in routing instability and availability impact. The vulnerability affects multiple versions of Junos OS and Junos OS Evolved prior to specific patched releases. Exploitation does not require authentication or user interaction but can cause significant network disruption. No known exploits are currently reported in the wild. European organizations relying on Juniper routing infrastructure could experience network outages and degraded service availability. Mitigation requires timely patching to fixed Junos OS versions. Countries with high Juniper market penetration and critical network infrastructure are most at risk.
A NULL Pointer Dereference vulnerability in the chassis daemon (chassisd) of Juniper Networks Junos OS on MX, SRX and EX Series allows a local attacker with low privileges to cause a Denial-of-Service (DoS).
When a user executes the 'show chassis' command with specifically crafted options, chassisd will crash and restart. Due to this all components but the Routing Engine (RE) in the chassis are reinitialized, which leads to a complete service outage, which the system automatically recovers from.
This issue affects:
Junos OS on MX, SRX and EX Series, except MX10000 Series and MX304:
* all versions before 22.4R3-S8,
* 23.2 versions before 23.2R2-S5,
* 23.4 versions before 23.4R2-S6,
* 24.2 versions before 24.2R2-S2,
* 24.4 versions before 24.4R2.
CVE-2025-60003 is a high-severity buffer over-read vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved. An unauthenticated attacker can exploit this by sending a crafted BGP update containing specific optional transitive attributes over an established peering session, causing rpd to crash and restart, resulting in a denial-of-service (DoS). This vulnerability only triggers if one or both BGP peers are non-4-byte-AS capable, which is not the default behavior unless explicitly disabled. It affects multiple versions of Junos OS and Junos OS Evolved prior to certain patch releases. The vulnerability has a CVSS score of 7.5, indicating high severity, with no known exploits in the wild currently. European organizations using affected Juniper routing devices with BGP peering configurations that disable 4-byte AS support are at risk. Mitigation requires upgrading to fixed Junos OS versions and verifying BGP peer capabilities to avoid triggering the flaw.
CVE-2025-59961 is a medium-severity vulnerability in Juniper Networks Junos OS and Junos OS Evolved affecting the DHCP daemon (jdhcpd). It allows a local, low-privileged user to write to the Unix socket managing the DHCP service, enabling administrative control over the DHCP server or relay. This flaw arises from incorrect permission assignments on a critical resource, permitting unauthorized command execution without user interaction. The vulnerability impacts multiple Junos OS versions prior to various patch releases starting from 21.2R3-S10 and corresponding Junos OS Evolved versions. Exploitation requires local access but no elevated privileges or user interaction. Although no known exploits are reported in the wild, the ability to control DHCP services can disrupt network operations and potentially facilitate further attacks. European organizations using affected Juniper devices should prioritize patching to mitigate risks.
CVE-2025-59960 is a high-severity vulnerability in Juniper Networks Junos OS and Junos OS Evolved affecting the DHCP relay agent. The flaw allows a DHCP client in one subnet to exhaust DHCP address pools of other subnets by exploiting improper handling of DHCP Option 82 in 'forward-only' mode. This leads to denial of service (DoS) on downstream DHCP servers by depleting available IP addresses. The vulnerability affects multiple Junos OS versions prior to various fixed releases starting from 21.2R3-S10 and corresponding Junos OS Evolved versions. Exploitation requires network access but no authentication or user interaction, with a CVSS score of 7.4. No known exploits are currently reported in the wild. European organizations using vulnerable Juniper devices should prioritize patching and consider network segmentation and DHCP relay configuration hardening to mitigate risk.
An Untrusted Pointer Dereference vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a local, authenticated attacker with low privileges to cause a Denial-of-Service (DoS).
When the command 'show route < ( receive-protocol | advertising-protocol ) bgp > detail' is executed, and at least one of the routes in the intended output has specific attributes, this will cause an rpd crash and restart.
'show route ... extensive' is not affected.
This issue affects:
Junos OS:
* all versions before 22.4R3-S8,
* 23.2 versions before 23.2R2-S5,
* 23.4 versions before 23.4R2-S5,
* 24.2 versions before 24.2R2-S2,
* 24.4 versions before 24.4R2;

* 23.4 versions before 23.4R2-S6-EVO,
* 24.2 versions before 24.2R2-S2-EVO,
* 24.4 versions before 24.4R2-EVO.
A clickjacking vulnerability exists in the web portal of Juniper Networks Paragon Automation (Pathfinder, Planner, Insights) due to the application's failure to set appropriate X-Frame-Options and X-Content-Type HTTP headers. This vulnerability allows an attacker to trick users into interacting with the interface under the attacker's control.
This issue affects all versions of Paragon Automation (Pathfinder, Planner, Insights) before 24.1.1.
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.
An Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Juniper Networks Junos Space allows an attacker to inject script tags in the
CLI Configlet
page that, when visited by another user, enables the attacker to execute commands with the target's permissions, including an administrator.
This issue affects all versions of Junos Space before 24.1R4.
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:
