| CVE-2025-30661 | 2 Juniper, Juniper Networks | 10 Ex9200-15c, Junos, Lc4800 and 7 more | 2026-01-26 | 7.3 High |
| An Incorrect Permission Assignment for Critical Resource vulnerability in line card script processing of Juniper Networks Junos OS allows a local, low-privileged user to install scripts to be executed as root, leading to privilege escalation. A local user with access to the local file system can copy a script to the router in a way that will be executed as root, as the system boots. Execution of the script as root can lead to privilege escalation, potentially providing the adversary complete control of the system. This issue only affects specific line cards, such as the MPC10, MPC11, LC4800, LC9600, MX304-LMIC16, SRX4700, and EX9200-15C. This issue affects Junos OS: * from 23.2 before 23.2R2-S4, * from 23.4 before 23.4R2-S5, * from 24.2 before 24.2R2-S1, * from 24.4 before 24.4R1-S3, 24.4R2. This issue does not affect versions prior to 23.1R2. | ||||

| An Out-of-bounds Write vulnerability in the connectivity fault management (CFM) daemon of Juniper Networks Junos OS on MX Series with MPC-BUILTIN, MPC1 through MPC9 line cards allows an unauthenticated adjacent attacker to send a malformed packet to the device, leading to an FPC crash and restart, resulting in a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks: Junos OS: * All versions before 22.2R3-S1, * from 22.4 before 22.4R2. This feature is not enabled by default. | ||||
| CVE-2024-47501 | 2 Juniper, Juniper Networks | 17 Ex9200, Ex9200-15c, Junos and 14 more | 2026-01-26 | 5.5 Medium |
| A NULL Pointer Dereference vulnerability in the packet forwarding engine (pfe) of Juniper Networks Junos OS on MX304, MX with MPC10/11/LC9600, and EX9200 with EX9200-15C allows a locally authenticated attacker with low privileges to cause a Denial of Service (DoS). In a VPLS or Junos Fusion scenario, the execution of specific show commands will cause all FPCs hosting VPLS sessions or connecting to satellites to crash and restart. This issue affects Junos on MX304, MX with MPC10/11/LC9600 and EX9200 with EX9200-15C: * All version before 21.2R3-S1, * 21.3 versions before 21.3R3, * 21.4 versions before 21.4R2. | ||||
| CVE-2024-47496 | 2 Juniper, Juniper Networks | 34 2x100ge \+ 4x10ge Mpc5e, 2x100ge \+ 4x10ge Mpc5eq, 2x100ge \+ 8x10ge Mpc4e and 31 more | 2026-01-26 | 5.5 Medium |
| A NULL Pointer Dereference vulnerability in the Packet Forwarding Engine (pfe) of Juniper Networks Junos OS allows a local, low-privileged attacker to cause a Denial-of-Service (DoS). When a specific command is executed, the pfe crashes. This will cause traffic forwarding to be interrupted until the system self-recovers. Repeated execution will create a sustained DoS condition. This issue only affects MX Series devices with Line cards MPC1-MPC9. This issue affects: Junos OS on MX Series: * All versions before 21.4R3-S9, * from 22.2 before 22.2R3-S5, * from 22.3 before 22.3R3-S4, * from 22.4 before 22.4R3-S2, * from 23.2 before 23.2R2-S1, * from 23.4 before 23.4R2. | ||||
| CVE-2024-39526 | 1 Juniper | 27 Ex9200, Ex9200-15c, Junos and 24 more | 2026-01-23 | 6.5 Medium |
| An Improper Handling of Exceptional Conditions vulnerability in packet processing of Juniper Networks Junos OS on MX Series with MPC10/MPC11/LC9600 line cards, EX9200 with EX9200-15C lines cards, MX304 devices, and Juniper Networks Junos OS Evolved on PTX Series, allows an attacker sending malformed DHCP packets to cause ingress packet processing to stop, leading to a Denial of Service (DoS). Continued receipt and processing of these packets will create a sustained Denial of Service (DoS) condition. This issue only occurs if DHCP snooping is enabled. See configuration below. This issue can be detected using following commands. Their output will display the interface status going down: user@device>show interfaces <if--x/x/x> user@device>show log messages | match <if--x/x/x> user@device>show log messages ==> will display the "[Error] Wedge-Detect : Host Loopback Wedge Detected: PFE: no," logs. This issue affects: Junos OS on MX Series with MPC10/MPC11/LC9600 line cards, EX9200 with EX9200-15C line cards, and MX304: * All versions before 21.2R3-S7, * from 21.4 before 21.4R3-S6, * from 22.2 before 22.2R3-S3, * all versions of 22.3, * from 22.4 before 22.4R3, * from 23.2 before 23.2R2; Junos OS Evolved on PTX Series: * from 19.3R1-EVO before 21.2R3-S8-EVO, * from 21.4-EVO before 21.4R3-S7-EVO, * from 22.1-EVO before 22.1R3-S6-EVO, * from 22.2-EVO before 22.2R3-S5-EVO, * from 22.3-EVO before 22.3R3-S3-EVO, * from 22.4-EVO before 22.4R3-S1-EVO, * from 23.2-EVO before 23.2R2-S2-EVO, * from 23.4-EVO before 23.4R2-EVO. Junos OS Evolved releases prior to 19.3R1-EVO are unaffected by this vulnerability | ||||
| CVE-2024-21593 | 1 Juniper | 14 Junos, Lc9600, Mpc10 and 11 more | 2026-01-23 | 6.5 Medium |
| An Improper Check or Handling of Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS). If an attacker sends a specific MPLS packet, which upon processing, causes an internal loop, that leads to a PFE crash and restart. Continued receipt of these packets leads to a sustained Denial of Service (DoS) condition. Circuit cross-connect (CCC) needs to be configured on the device for it to be affected by this issue. This issue only affects MX Series with MPC10, MPC11, LC9600, and MX304. This issue affects: Juniper Networks Junos OS 21.4 versions from 21.4R3 earlier than 21.4R3-S5; 22.2 versions from 22.2R2 earlier than 22.2R3-S2; 22.3 versions from 22.3R1 earlier than 22.3R2-S2; 22.3 versions from 22.3R3 earlier than 22.3R3-S1 22.4 versions from 22.4R1 earlier than 22.4R2-S2, 22.4R3; 23.2 versions earlier than 23.2R1-S1, 23.2R2. | ||||
| CVE-2024-30401 | 2 Juniper, Juniper Networks | 17 Ex9200-15c, Junos, Lc9600 and 14 more | 2026-01-23 | 5.9 Medium |
| An Out-of-bounds Read vulnerability in the advanced forwarding management process aftman of Juniper Networks Junos OS on MX Series with MPC10E, MPC11, MX10K-LC9600 line cards, MX304, and EX9200-15C, may allow an attacker to exploit a stack-based buffer overflow, leading to a reboot of the FPC. Through code review, it was determined that the interface definition code for aftman could read beyond a buffer boundary, leading to a stack-based buffer overflow. This issue affects Junos OS on MX Series and EX9200-15C: * from 21.2 before 21.2R3-S1, * from 21.4 before 21.4R3, * from 22.1 before 22.1R2, * from 22.2 before 22.2R2; This issue does not affect: * versions of Junos OS prior to 20.3R1; * any version of Junos OS 20.4. | ||||
