CVSS: 7.5EPSS: 0%CPEs: 48EXPL: 0CVE-2023-28985 – SRX Series and MX Series: An FPC core is observed when IDP is enabled on the device and a specific malformed SSL packet is received
https://notcve.org/view.php?id=CVE-2023-28985
An Improper Validation of Syntactic Correctness of Input vulnerability in Intrusion Detection and Prevention (IDP) of Juniper Networks SRX Series and MX Series allows an unauthenticated, network-based attacker to cause Denial of Service (DoS). Continued receipt of this specific packet will cause a sustained Denial of Service condition. On all SRX Series and MX Series platforms, where IDP is enabled and a specific malformed SSL packet is received, the SSL detector crashes leading to an FPC core. This issue affects Juniper Networks SRX Series and MX Series prior to SigPack 3598. In order to identify the current SigPack version, following command can be used: user@junos# show security idp security-package-version • https://supportportal.juniper.net/JSA71662 • CWE-1286: Improper Validation of Syntactic Correctness of Input •
CVSS: 5.5EPSS: 0%CPEs: 131EXPL: 0CVE-2023-36838 – Junos OS: SRX Series: A flowd core occurs when running a low privileged CLI command
https://notcve.org/view.php?id=CVE-2023-36838
An Out-of-bounds Read vulnerability in the flow processing daemon (flowd) of Juniper Networks Junos OS on SRX Series allows a local, authenticated attacker with low privileges, to cause a Denial of Service (DoS). If a low privileged user executes a specific CLI command, flowd which is responsible for traffic forwarding in SRX crashes and generates a core dump. This will cause temporary traffic interruption until the flowd process is restarted automatically. Continued execution of this command will lead to a sustained DoS. This issue affects Juniper Networks Junos OS on SRX Series: All versions prior to 20.2R3-S7; 20.3 version 20.3R1 and later versions; 20.4 versions prior to 20.4R3-S6; 21.1 versions prior to 21.1R3-S5; 21.2 versions prior to 21.2R3-S4; 21.3 versions prior to 21.3R3-S4; 21.4 versions prior to 21.4R3-S3; 22.1 versions prior to 22.1R3-S1; 22.2 versions prior to 22.2R3; 22.3 versions prior to 22.3R2; 22.4 versions prior to 22.4R1-S1, 22.4R2. • https://supportportal.juniper.net/JSA71645 • CWE-125: Out-of-bounds Read •
CVSS: 7.5EPSS: 0%CPEs: 42EXPL: 0CVE-2023-36831 – Junos OS: SRX Series: jbuf memory leak when SSL Proxy and UTM Web-Filtering is applied
https://notcve.org/view.php?id=CVE-2023-36831
An Improper Check or Handling of Exceptional Conditions vulnerability in the UTM (Unified Threat Management) Web-Filtering feature of Juniper Networks Junos OS on SRX Series causes a jbuf memory leak to occur when accessing certain websites, eventually leading to a Denial of Service (DoS) condition. Service restoration is only possible by rebooting the system. The jbuf memory leak only occurs in SSL Proxy and UTM Web-Filtering configurations. Other products, platforms, and configurations are not affected by this vulnerability. This issue affects Juniper Networks Junos OS on SRX Series: 22.2 versions prior to 22.2R3; 22.3 versions prior to 22.3R2-S1, 22.3R3; 22.4 versions prior to 22.4R1-S2, 22.4R2. This issue does not affect Juniper Networks Junos OS versions prior to 22.2R2. • https://supportportal.juniper.net/JSA71636 • CWE-703: Improper Check or Handling of Exceptional Conditions •
CVSS: 7.5EPSS: 0%CPEs: 79EXPL: 0CVE-2022-22201 – SRX5000 Series with SPC3, SRX4000 Series, and vSRX: When PowerMode IPsec is configured, the PFE will crash upon receipt of a malformed ESP packet
https://notcve.org/view.php?id=CVE-2022-22201
An Improper Validation of Specified Index, Position, or Offset in Input vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows an unauthenticated network-based attacker to cause a Denial of Service (DoS). On SRX5000 Series with SPC3, SRX4000 Series, and vSRX, when PowerMode IPsec is configured and a malformed ESP packet matching an established IPsec tunnel is received the PFE crashes. This issue affects Juniper Networks Junos OS on SRX5000 Series with SPC3, SRX4000 Series, and vSRX: All versions prior to 19.4R2-S6, 19.4R3-S7; 20.1 versions prior to 20.1R3-S3; 20.2 versions prior to 20.2R3-S4; 20.3 versions prior to 20.3R3-S3; 20.4 versions prior to 20.4R3-S2; 21.1 versions prior to 21.1R3; 21.2 versions prior to 21.2R3; 21.3 versions prior to 21.3R1-S2, 21.3R2. Una vulnerabilidad de comprobación inapropiada del índice, la posición o el desplazamiento especificados en la entrada en Packet Forwarding Engine (PFE) de Juniper Networks Junos OS permite a un atacante no autenticado basado en la red causar una Denegación de Servicio (DoS). En las series SRX5000 con SPC3, SRX4000 y vSRX, cuando es configurado PowerMode IPsec y es recibido un paquete ESP malformado que coincide con un túnel IPsec establecido, el PFE es bloqueado. • https://kb.juniper.net/JSA69900 • CWE-20: Improper Input Validation CWE-1285: Improper Validation of Specified Index, Position, or Offset in Input •
