A Heap-based Buffer Overflow vulnerability in the Network Services Daemon (NSD) of Juniper Networks Junos OS allows authenticated, low privileged, local attacker to cause a Denial of Service (DoS). On an SRX 5000 Series device, when executing a specific command repeatedly, memory is corrupted, which leads to a Flow Processing Daemon (flowd) crash. The NSD process has to be restarted to restore services. If this issue occurs, it can be checked with the following command: user@host> request security policies check The following log message can also be observed: Error: policies are out of sync for PFE node<number>.fpc<number>.pic<number>. This issue affects: Juniper Networks Junos OS on SRX 5000 Series * All versions earlier than 20.4R3-S6; * 21.1 versions earlier than 21.1R3-S5; * 21.2 versions earlier than 21.2R3-S4; * 21.3 versions earlier than 21.3R3-S3; * 21.4 versions earlier than 21.4R3-S3; * 22.1 versions earlier than 22.1R3-S1; * 22.2 versions earlier than 22.2R3; * 22.3 versions earlier than 22.3R2. Una vulnerabilidad de desbordamiento de búfer en la región Heap de la memoria en el Network Services Daemon (NSD) de Juniper Networks Junos OS permite que un atacante local autenticado y con pocos privilegios provoque una denegación de servicio (DoS). En un dispositivo de la serie SRX 5000, al ejecutar un comando específico repetidamente, la memoria se daña, lo que provoca un bloqueo del Flow Processing Daemon (flowd). El proceso NSD debe reiniciarse para restaurar los servicios. Si ocurre este problema, se puede verificar con el siguiente comando: usuario@host&gt; solicitar políticas de seguridad verificar También se puede observar el siguiente mensaje de registro: Error: policies are out of sync for PFE node.fpc.pic. • https://supportportal.juniper.net/JSA75733 https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

An Out-of-bounds Write vulnerability in J-Web of Juniper Networks Junos OS on SRX Series and EX Series allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS), or Remote Code Execution (RCE) and obtain root privileges on the device. This issue is caused by use of an insecure function allowing an attacker to overwrite arbitrary memory. This issue affects Juniper Networks Junos OS SRX Series and EX Series: * Junos OS versions earlier than 20.4R3-S9; * Junos OS 21.2 versions earlier than 21.2R3-S7; * Junos OS 21.3 versions earlier than 21.3R3-S5; * Junos OS 21.4 versions earlier than 21.4R3-S5; * Junos OS 22.1 versions earlier than 22.1R3-S4; * Junos OS 22.2 versions earlier than 22.2R3-S3; * Junos OS 22.3 versions earlier than 22.3R3-S2; * Junos OS 22.4 versions earlier than 22.4R2-S2, 22.4R3. Una vulnerabilidad de escritura fuera de los límites en J-Web de Juniper Networks Junos OS en las series SRX y EX permite que un atacante basado en red no autenticado provoque una denegación de servicio (DoS) o una ejecución remota de código (RCE) y obtenga privilegios de root en el dispositivo. Este problema se debe al uso de una función insegura que permite a un atacante sobrescribir la memoria arbitraria. Este problema afecta a las series Junos OS SRX y EX de Juniper Networks: * Versiones de Junos OS anteriores a 20.4R3-S9; * Versiones de Junos OS 21.2 anteriores a 21.2R3-S7; * Versiones de Junos OS 21.3 anteriores a 21.3R3-S5; * Versiones de Junos OS 21.4 anteriores a 21.4R3-S5; * Versiones de Junos OS 22.1 anteriores a 22.1R3-S4; * Versiones de Junos OS 22.2 anteriores a 22.2R3-S3; * Versiones de Junos OS 22.3 anteriores a 22.3R3-S2; * Versiones de Junos OS 22.4 anteriores a 22.4R2-S2, 22.4R3. • https://curesec.com/blog/article/CVE-2024-21591_Juniper_Remote_Code_Exec.html https://supportportal.juniper.net/JSA75729 https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N • CWE-787: Out-of-bounds Write •

An Improper Access Control vulnerability in the Juniper Networks Paragon Active Assurance Control Center allows an unauthenticated network-based attacker to access reports without authenticating, potentially containing sensitive configuration information. A feature was introduced in version 3.1.0 of the Paragon Active Assurance Control Center which allows users to selectively share account data. By exploiting this vulnerability, it is possible to access reports without being logged in, resulting in the opportunity for malicious exfiltration of user data. Note that the Paragon Active Assurance Control Center SaaS offering is not affected by this issue. This issue affects Juniper Networks Paragon Active Assurance versions 3.1.0, 3.2.0, 3.2.2, 3.3.0, 3.3.1, 3.4.0. This issue does not affect Juniper Networks Paragon Active Assurance versions earlier than 3.1.0. Una vulnerabilidad de control de acceso inadecuado en Juniper Networks Paragon Active Assurance Control Center permite que un atacante basado en red no autenticado acceda a informes sin autenticarse, que potencialmente contienen información de configuración confidencial. Se introdujo una función en la versión 3.1.0 del Centro de control de Paragon Active Assurance que permite a los usuarios compartir datos de cuentas de forma selectiva. Al explotar esta vulnerabilidad, es posible acceder a informes sin iniciar sesión, lo que genera la oportunidad de una filtración maliciosa de los datos del usuario. • https://supportportal.juniper.net/JSA75727 https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N • CWE-284: Improper Access Control •

An Improper Handling of Exceptional Conditions vulnerability in the broadband edge subscriber management daemon (bbe-smgd) of Juniper Networks Junos OS on MX Series allows an attacker directly connected to the vulnerable system who repeatedly flaps DHCP subscriber sessions to cause a slow memory leak, ultimately leading to a Denial of Service (DoS). Memory can only be recovered by manually restarting bbe-smgd. This issue only occurs if BFD liveness detection for DHCP subscribers is enabled. Systems without BFD liveness detection enabled are not vulnerable to this issue. Indication of the issue can be observed by periodically executing the 'show system processes extensive' command, which will indicate an increase in memory allocation for bbe-smgd. A small amount of memory is leaked every time a DHCP subscriber logs in, which will become visible over time, ultimately leading to memory starvation. user@junos> show system processes extensive | match bbe-smgd 13071 root 24 0 415M 201M select 0 0:41 7.28% bbe-smgd{bbe-smgd} 13071 root 20 0 415M 201M select 1 0:04 0.00% bbe-smgd{bbe-smgd} ... user@junos> show system processes extensive | match bbe-smgd 13071 root 20 0 420M 208M select 0 4:33 0.10% bbe-smgd{bbe-smgd} 13071 root 20 0 420M 208M select 0 0:12 0.00% bbe-smgd{bbe-smgd} ...

An Improper Handling of Exceptional Conditions vulnerability in BGP session processing of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated network-based attacker, using specific timing outside the attacker's control, to flap BGP sessions and cause the routing protocol daemon (rpd) process to crash and restart, leading to a Denial of Service (DoS) condition. Continued BGP session flapping will create a sustained Denial of Service (DoS) condition. This issue only affects routers configured with non-stop routing (NSR) enabled. Graceful Restart (GR) helper mode, enabled by default, is also required for this issue to be exploitable. Note: NSR is not supported on the SRX Series and is therefore not affected by this vulnerability. When the BGP session flaps on the NSR-enabled router, the device enters GR-helper/LLGR-helper mode due to the peer having negotiated GR/LLGR-restarter capability and the backup BGP requests for replication of the GR/LLGR-helper session, master BGP schedules, and initiates replication of GR/LLGR stale routes to the backup BGP. In this state, if the BGP session with the BGP peer comes up again, unsolicited replication is initiated for the peer without cleaning up the ongoing GR/LLGR-helper mode replication. This parallel two instances of replication for the same peer leads to the assert if the BGP session flaps again.
