CVSS: 8.8EPSS: 0%CPEs: 89EXPL: 0CVE-2021-31354 – Junos OS and Junos OS Evolved: A vulnerability in the Juniper Agile License Client may allow an attacker to perform Remote Code Execution (RCE)
https://notcve.org/view.php?id=CVE-2021-31354
An Out Of Bounds (OOB) access vulnerability in the handling of responses by a Juniper Agile License (JAL) Client in Juniper Networks Junos OS and Junos OS Evolved, configured in Network Mode (to use Juniper Agile License Manager) may allow an attacker to cause a partial Denial of Service (DoS), or lead to remote code execution (RCE). The vulnerability exists in the packet parsing logic on the client that processes the response from the server using a custom protocol. An attacker with control of a JAL License Manager, or with access to the local broadcast domain, may be able to spoof a new JAL License Manager and/or craft a response to the Junos OS License Client, leading to exploitation of this vulnerability. This issue only affects Junos systems configured in Network Mode. Systems that are configured in Standalone Mode (the default mode of operation for all systems) are not vulnerable to this issue. • https://kb.juniper.net/JSA11219 • CWE-125: Out-of-bounds Read •
CVSS: 7.5EPSS: 0%CPEs: 22EXPL: 1CVE-2021-31353 – Junos OS and Junos OS Evolved: RPD core upon receipt of specific BGP update
https://notcve.org/view.php?id=CVE-2021-31353
An Improper Handling of Exceptional Conditions vulnerability in Juniper Networks Junos OS and Junos OS Evolved allows an attacker to inject a specific BGP update, causing the routing protocol daemon (RPD) to crash and restart, leading to a Denial of Service (DoS). Continued receipt and processing of the BGP update will create a sustained Denial of Service (DoS) condition. This issue affects very specific versions of Juniper Networks Junos OS: 19.3R3-S2; 19.4R3-S3; 20.2 versions 20.2R2-S3 and later, prior to 20.2R3-S2; 20.3 versions 20.3R2 and later, prior to 20.3R3; 20.4 versions 20.4R2 and later, prior to 20.4R3; 21.1 versions prior to 21.1R2. Juniper Networks Junos OS 20.1 is not affected by this issue. This issue also affects Juniper Networks Junos OS Evolved: All versions prior to 20.4R2-S3-EVO, 20.4R3-EVO; 21.1-EVO versions prior to 21.1R2-EVO; 21.2-EVO versions prior to 21.2R2-EVO. • https://kb.juniper.net/JSA11218 • CWE-755: Improper Handling of Exceptional Conditions •
CVSS: 5.3EPSS: 0%CPEs: 1EXPL: 1CVE-2021-31352 – SRC Series: NETCONF over SSH allows negotiation of weak ciphers
https://notcve.org/view.php?id=CVE-2021-31352
An Information Exposure vulnerability in Juniper Networks SRC Series devices configured for NETCONF over SSH permits the negotiation of weak ciphers, which could allow a remote attacker to obtain sensitive information. A remote attacker with read and write access to network data could exploit this vulnerability to display plaintext bits from a block of ciphertext and obtain sensitive information. This issue affects all Juniper Networks SRC Series versions prior to 4.13.0-R6. Una vulnerabilidad de exposición de información en los dispositivos de Juniper Networks SRC Series configurados para NETCONF sobre SSH permite una negociación de cifrados débiles, lo que podría permitir a un atacante remoto conseguir información confidencial. Un atacante remoto con acceso de lectura y escritura a los datos de la red podría aprovechar esta vulnerabilidad para mostrar bits de texto plano de un bloque de texto cifrado y conseguir información confidencial. • https://kb.juniper.net/JSA11217 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
CVSS: 7.5EPSS: 0%CPEs: 47EXPL: 0CVE-2021-31351 – Junos OS: MX Series: Receipt of specific packet on MS-MPC/MS-MIC causes line card reset
https://notcve.org/view.php?id=CVE-2021-31351
An Improper Check for Unusual or Exceptional Conditions in packet processing on the MS-MPC/MS-MIC utilized by Juniper Networks Junos OS allows a malicious attacker to send a specific packet, triggering the MS-MPC/MS-MIC to reset, causing a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue only affects specific versions of Juniper Networks Junos OS on MX Series: 17.3R3-S11; 17.4R2-S13; 17.4R3 prior to 17.4R3-S5; 18.1R3-S12; 18.2R2-S8, 18.2R3-S7, 18.2R3-S8; 18.3R3-S4; 18.4R3-S7; 19.1R3-S4, 19.1R3-S5; 19.2R1-S6; 19.3R3-S2; 19.4R2-S4, 19.4R2-S5; 19.4R3-S2; 20.1R2-S1; 20.2R2-S2, 20.2R2-S3, 20.2R3; 20.3R2, 20.3R2-S1; 20.4R1, 20.4R1-S1, 20.4R2; 21.1R1; This issue does not affect any version of Juniper Networks Junos OS prior to 15.1X49-D240; Una comprobación inapropiada de condiciones inusuales o excepcionales en el procesamiento de paquetes en el MS-MPC/MS-MIC usado por Juniper Networks Junos OS permite a un atacante malicioso enviar un paquete específico, haciendo que el MS-MPC/MS-MIC se reinicie, causando una Denegación de Servicio (DoS). Si se sigue recibiendo y procesando este paquete, se creará una condición de Denegación de Servicio (DoS) sostenida.
