| CVE-2025-59962 | 1 Juniper | 2 Junos Os, Junos Os Evolved | 2025-10-10 | 5.3 Medium |
| 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. | ||||
| CVE-2025-59957 | 1 Juniper | 1 Junos Os | 2025-10-10 | 6.8 Medium |
| 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. | ||||
| CVE-2025-52960 | 1 Juniper | 1 Junos Os | 2025-10-10 | 5.9 Medium |
| 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. | ||||
| CVE-2025-60010 | 1 Juniper | 2 Junos Os, Junos Os Evolved | 2025-10-10 | 5.4 Medium |
| 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. | ||||
| CVE-2025-59964 | 1 Juniper | 2 Junos Os, Srx4700 | 2025-10-10 | 7.5 High |
| 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. | ||||
| CVE-2025-60004 | 1 Juniper | 2 Junos Os, Junos Os Evolved | 2025-10-10 | 7.5 High |
| 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. | ||||
| CVE-2024-39542 | 1 Juniper | 3 Junos, Junos Os, Junos Os Evolved | 2025-08-08 | 7.5 High |
| 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. | ||||
| CVE-2024-39549 | 1 Juniper | 3 Junos, Junos Os, Junos Os Evolved | 2025-02-26 | 7.5 High |
| A Missing Release of Memory after Effective Lifetime 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 memory is not properly freed in all circumstances, leading to a Denial of Service (DoS). Consumed memory can be freed by manually restarting Routing Protocol Daemon (rpd). Memory utilization could be monitored by: user@host> show system memory or show system monitor memory status This issue affects: Junos OS: * All versions before 21.2R3-S8, * from 21.4 before 21.4R3-S8, * from 22.2 before 22.2R3-S4, * from 22.3 before 22.3R3-S3, * from 22.4 before 22.4R3-S3, * from 23.2 before 23.2R2-S1, * from 23.4 before 23.4R1-S2, 23.4R2. Junos OS Evolved: * All versions before 21.2R3-S8-EVO, * from 21.4 before 21.4R3-S8-EVO, * from 22.2 before 22.2R3-S4-EVO, * from 22.3 before 22.3R3-S3-EVO, * from 22.4 before 22.4R3-S3-EVO, * from 23.2 before 23.2R2-S1-EVO, * from 23.4 before 23.4R1-S2-EVO, 23.4R2-EVO. | ||||
| CVE-2024-39556 | 1 Juniper | 3 Junos, Junos Os, Junos Os Evolved | 2025-02-07 | 6.4 Medium |
| A Stack-Based Buffer Overflow vulnerability in Juniper Networks Junos OS and Juniper Networks Junos OS Evolved may allow a local, low-privileged attacker with access to the CLI the ability to load a malicious certificate file, leading to a limited Denial of Service (DoS) or privileged code execution. By exploiting the 'set security certificates' command with a crafted certificate file, a malicious attacker with access to the CLI could cause a crash of the command management daemon (mgd), limited to the local user's command interpreter, or potentially trigger a stack-based buffer overflow. This issue affects: Junos OS: * All versions before 21.4R3-S7, * from 22.1 before 22.1R3-S6, * from 22.2 before 22.2R3-S4, * from 22.3 before 22.3R3-S3, * from 22.4 before 22.4R3-S2, * from 23.2 before 23.2R2, * from 23.4 before 23.4R1-S1, 23.4R2; Junos OS Evolved: * All versions before 21.4R3-S7-EVO, * from 22.1-EVO before 22.1R3-S6-EVO, * from 22.2-EVO before 22.2R3-S4-EVO, * from 22.3-EVO before 22.3R3-S3-EVO, * from 22.4-EVO before 22.4R3-S2-EVO, * from 23.2-EVO before 23.2R2-EVO, * from 23.4-EVO before 23.4R1-S1-EVO, 23.4R2-EVO. | ||||
| CVE-2024-39555 | 1 Juniper | 3 Junos, Junos Os, Junos Os Evolved | 2025-02-07 | 7.5 High |
| An Improper Handling of Exceptional Conditions vulnerability in the Routing Protocol Daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows an attacker sending a specific malformed BGP update message to cause the session to reset, resulting in a Denial of Service (DoS). Continued receipt and processing of these malformed BGP update messages will create a sustained Denial of Service (DoS) condition. Upon receipt of a BGP update message over an established BGP session containing a specifically malformed tunnel encapsulation attribute, when segment routing is enabled, internal processing of the malformed attributes within the update results in improper parsing of remaining attributes, leading to session reset: BGP SEND Notification code 3 (Update Message Error) subcode 1 (invalid attribute list) Only systems with segment routing enabled are vulnerable to this issue. This issue affects eBGP and iBGP, in both IPv4 and IPv6 implementations, and requires a remote attacker to have at least one established BGP session. This issue affects: Junos OS: * All versions before 21.4R3-S8, * from 22.2 before 22.2R3-S4, * from 22.3 before 22.3R3-S3, * from 22.4 before 22.4R3-S3, * from 23.2 before 23.2R2-S1, * from 23.4 before 23.4R1-S2, 23.4R2. Junos OS Evolved: * All versions before 21.4R3-S8-EVO, * from 22.2-EVO before 22.2R3-S4-EVO, * from 22.3-EVO before 22.3R3-S3-EVO, * from 22.4-EVO before 22.4R3-S3-EVO, * from 23.2-EVO before 23.2R2-S1-EVO, * from 23.4-EVO before 23.4R1-S2-EVO, 23.4R2-EVO. | ||||
| CVE-2024-39565 | 1 Juniper | 1 Junos Os | 2024-11-21 | 8.8 High |
| An Improper Neutralization of Data within XPath Expressions ('XPath Injection') vulnerability in J-Web shipped with Juniper Networks Junos OS allows an unauthenticated, network-based attacker to execute remote commands on the target device. While an administrator is logged into a J-Web session or has previously logged in and subsequently logged out of their J-Web session, the attacker can arbitrarily execute commands on the target device with the other user's credentials. In the worst case, the attacker will have full control over the device. This issue affects Junos OS: * All versions before 21.2R3-S8, * from 21.4 before 21.4R3-S7, * from 22.2 before 22.2R3-S4, * from 22.3 before 22.3R3-S3, * from 22.4 before 22.4R3-S2, * from 23.2 before 23.2R2, * from 23.4 before 23.4R1-S1, 23.4R2. | ||||
