CVSS: 5.5EPSS: 0%CPEs: 193EXPL: 0CVE-2023-22398 – Junos OS and Junos OS Evolved: RPD might crash when MPLS ping is performed on BGP LSPs
https://notcve.org/view.php?id=CVE-2023-22398
An Access of Uninitialized Pointer vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a locally authenticated attacker with low privileges to cause a Denial of Service (DoS). When an MPLS ping is performed on BGP LSPs, the RPD might crash. Repeated execution of this operation will lead to a sustained DoS. This issue affects: Juniper Networks Junos OS: 15.1 versions prior to 15.1R7-S12; 19.1 versions prior to 19.1R3-S9; 19.2 versions prior to 19.2R1-S9, 19.2R3-S5; 19.3 versions prior to 19.3R3-S6; 19.4 versions prior to 19.4R2-S7, 19.4R3-S8; 20.1 versions prior to 20.1R3-S4; 20.2 versions prior to 20.2R3-S5; 20.3 versions prior to 20.3R3-S5; 20.4 versions prior to 20.4R3-S4; 21.1 versions prior to 21.1R1-S1, 21.1R2; Juniper Networks Junos OS Evolved: All versions prior to 20.4R3-S4; 21.1 versions prior to 21.1R2-EVO. Una vulnerabilidad de acceso de puntero no inicializado en el demonio de protocolo de enrutamiento (rpd) de Juniper Networks Junos OS y Junos OS Evolved permite que un atacante autenticado localmente con privilegios bajos provoque una denegación de servicio (DoS). • https://kb.juniper.net/JSA70181 • CWE-824: Access of Uninitialized Pointer •
CVSS: 7.5EPSS: 0%CPEs: 150EXPL: 1CVE-2023-22415 – Junos OS: MX Series and SRX Series: The flow processing daemon (flowd) will crash when specific H.323 packets are received
https://notcve.org/view.php?id=CVE-2023-22415
An Out-of-Bounds Write vulnerability in the H.323 ALG of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause Denial of Service (DoS). On all MX Series and SRX Series platform, when H.323 ALG is enabled and specific H.323 packets are received simultaneously, a flow processing daemon (flowd) crash will occur. Continued receipt of these specific packets will cause a sustained Denial of Service (DoS) condition. This issue affects: Juniper Networks Junos OS on MX Series and SRX Series All versions prior to 19.4R3-S10; 20.2 versions prior to 20.2R3-S6; 20.3 versions prior to 20.3R3-S6; 20.4 versions prior to 20.4R3-S5; 21.1 versions prior to 21.1R3-S4; 21.2 versions prior to 21.2R3-S3; 21.3 versions prior to 21.3R3-S3; 21.4 versions prior to 21.4R3; 22.1 versions prior to 22.1R2-S1, 22.1R3; 22.2 versions prior to 22.2R1-S2, 22.2R2. Una vulnerabilidad de escritura fuera de los límites en el ALG H.323 de Juniper Networks Junos OS permite que un atacante basado en red no autenticado provoque una denegación de servicio (DoS). • https://kb.juniper.net/JSA70211 • CWE-787: Out-of-bounds Write •
CVSS: 6.5EPSS: 0%CPEs: 154EXPL: 0CVE-2023-22404 – Junos OS: SRX Series and MX Series with SPC3: When IPsec VPN is configured iked will core when a specifically formatted payload is received
https://notcve.org/view.php?id=CVE-2023-22404
An Out-of-bounds Write vulnerability in the Internet Key Exchange Protocol daemon (iked) of Juniper Networks Junos OS on SRX series and MX with SPC3 allows an authenticated, network-based attacker to cause a Denial of Service (DoS). iked will crash and restart, and the tunnel will not come up when a peer sends a specifically formatted payload during the negotiation. This will impact other IKE negotiations happening at the same time. Continued receipt of this specifically formatted payload will lead to continuous crashing of iked and thereby the inability for any IKE negotiations to take place. Note that this payload is only processed after the authentication has successfully completed. So the issue can only be exploited by an attacker who can successfully authenticate. • https://kb.juniper.net/JSA70200 • CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 0%CPEs: 45EXPL: 1CVE-2023-22410 – Junos OS: MX Series with MPC10/MPC11: When Suspicious Control Flow Detection (scfd) is enabled and an attacker is sending specific traffic, this causes a memory leak.
https://notcve.org/view.php?id=CVE-2023-22410
A Missing Release of Memory after Effective Lifetime vulnerability in the Juniper Networks Junos OS on MX Series platforms with MPC10/MPC11 line cards, allows an unauthenticated adjacent attacker to cause a Denial of Service (DoS). Devices are only vulnerable when the Suspicious Control Flow Detection (scfd) feature is enabled. Upon enabling this specific feature, an attacker sending specific traffic is causing memory to be allocated dynamically and it is not freed. Memory is not freed even after deactivating this feature. Sustained processing of such traffic will eventually lead to an out of memory condition that prevents all services from continuing to function, and requires a manual restart to recover. • https://kb.juniper.net/JSA70206 • CWE-401: Missing Release of Memory after Effective Lifetime •
CVSS: 7.5EPSS: 0%CPEs: 73EXPL: 0CVE-2023-22391 – Junos OS: ACX2K Series: Receipt of a high rate of specific traffic will lead to a Denial of Service (DoS)
https://notcve.org/view.php?id=CVE-2023-22391
A vulnerability in class-of-service (CoS) queue management in Juniper Networks Junos OS on the ACX2K Series devices allows an unauthenticated network-based attacker to cause a Denial of Service (DoS). Specific packets are being incorrectly routed to a queue used for other high-priority traffic such as BGP, PIM, ICMP, ICMPV6 ND and ISAKMP. Due to this misclassification of traffic, receipt of a high rate of these specific packets will cause delays in the processing of other traffic, leading to a Denial of Service (DoS). Continued receipt of this amount of traffic will create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks Junos OS on ACX2K Series: All versions prior to 19.4R3-S9; All 20.2 versions; 20.3 versions prior to 20.3R3-S6 on ACX2K Series; 20.4 versions prior to 20.4R3-S4 on ACX2K Series; All 21.1 versions; 21.2 versions prior to 21.2R3-S3 on ACX2K Series. • https://kb.juniper.net/JSA70187 • CWE-755: Improper Handling of Exceptional Conditions •
