CVSS: 5.3EPSS: 1%CPEs: 117EXPL: 2CVE-2023-36846 – Juniper Junos OS SRX Series Missing Authentication for Critical Function Vulnerability
https://notcve.org/view.php?id=CVE-2023-36846
A Missing Authentication for Critical Function vulnerability in Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause limited impact to the file system integrity. With a specific request to user.php that doesn't require authentication an attacker is able to upload arbitrary files via J-Web, leading to a loss of integrity for a certain part of the file system, which may allow chaining to other vulnerabilities. This issue affects Juniper Networks Junos OS on SRX Series: * All versions prior to 20.4R3-S8; * 21.1 versions 21.1R1 and later; * 21.2 versions prior to 21.2R3-S6; * 21.3 versions prior to 21.3R3-S5; * 21.4 versions prior to 21.4R3-S5; * 22.1 versions prior to 22.1R3-S3; * 22.2 versions prior to 22.2R3-S2; * 22.3 versions prior to 22.3R2-S2, 22.3R3; * 22.4 versions prior to 22.4R2-S1, 22.4R3.

CVSS: 9.8EPSS: 96%CPEs: 277EXPL: 17CVE-2023-36845 – Juniper Junos OS EX Series and SRX Series PHP External Variable Modification Vulnerability
https://notcve.org/view.php?id=CVE-2023-36845
A PHP External Variable Modification vulnerability in J-Web of Juniper Networks Junos OS on EX Series and SRX Series allows an unauthenticated, network-based attacker to remotely execute code. Using a crafted request which sets the variable PHPRC an attacker is able to modify the PHP execution environment allowing the injection und execution of code. This issue affects Juniper Networks Junos OS on EX Series and SRX Series: * All versions prior to 20.4R3-S9; * 21.1 versions 21.1R1 and later; * 21.2 versions prior to 21.2R3-S7; * 21.3 versions prior to 21.3R3-S5; * 21.4 versions prior to 21.4R3-S5; * 22.1 versions prior to 22.1R3-S4; * 22.2 versions prior to 22.2R3-S2; * 22.3 versions prior to 22.3R2-S2, 22.3R3-S1; * 22.4 versions prior to 22.4R2-S1, 22.4R3; * 23.2 versions prior to 23.2R1-S1, 23.2R2. Una vulnerabilidad de modificación de variable externa PHP en J-Web de Juniper Networks Junos OS en las series EX y SRX permite a un atacante no autenticado basado en red ejecutar código de forma remota. Mediante una solicitud manipulada que establece la variable PHPRC, un atacante puede modificar el entorno de ejecución de PHP, lo que permite la inyección y ejecución de código. Este problema afecta al sistema operativo Junos de Juniper Networks en las series EX y SRX: * Todas las versiones anteriores a 20.4R3-S9; * 21.1: versiones 21.1R1 y posteriores; * 21.2: versiones anteriores a 21.2R3-S7; * 21.3: versiones anteriores a 21.3R3-S5; * 21.4: versiones anteriores a 21.4R3-S5; * 22.1: versiones anteriores a 22.1R3-S4; * 22.2: versiones anteriores a 22.2R3-S2; * 22.3: versiones anteriores a 22.3R2-S2, 22.3R3-S1; * 22.4: versiones anteriores a 22.4R2-S1, 22.4R3; * 23.2: versiones anteriores a 23.2R1-S1, 23.2R2. Juniper Junos OS on EX Series and SRX Series contains a PHP external variable modification vulnerability that allows an unauthenticated, network-based attacker to control an important environment variable. • https://github.com/watchtowrlabs/juniper-rce_cve-2023-36844?ref=labs.watchtowr.com https://github.com/cyberh3als/CVE-2023-36845-POC https://github.com/imhunterand/CVE-2023-36845 https://github.com/CharonDefalt/Juniper-exploit-CVE-2023-36845 https://github.com/kljunowsky/CVE-2023-36845 https://github.com/zaenhaxor/CVE-2023-36845 https://github.com/ak1t4/CVE-2023-36845 https://github.com/halencarjunior/CVE-2023-36845 https://github.com/toanln-cov/CVE-2023-36845 https://github.com • CWE-473: PHP External Variable Modification •
CVSS: 6.5EPSS: 0%CPEs: 98EXPL: 0CVE-2023-36834 – Junos OS: SRX 4600 and SRX 5000 Series: The receipt of specific genuine packets by SRXes configured for L2 transparency will cause a DoS
https://notcve.org/view.php?id=CVE-2023-36834
An Incomplete Internal State Distinction vulnerability in the packet forwarding engine (PFE) of Juniper Networks Junos OS on SRX 4600 and SRX 5000 Series allows an adjacent attacker to cause a Denial of Service (DoS). If an SRX is configured in L2 transparent mode the receipt of a specific genuine packet can cause a single Packet Processing Engines (PPE) component of the PFE to run into a loop, which in turn will render the PPE unavailable. Each packet will cause one PPE to get into a loop, leading to a gradual performance degradation until all PPEs are unavailable and all traffic processing stops. To recover the affected FPC need to be restarted. This issue affects Juniper Networks Junos OS on SRX 4600 and SRX 5000 Series: 20.1 version 20.1R1 and later versions; 20.2 versions prior to 20.2R3-S7; 20.3 version 20.3R1 and later versions; 20.4 versions prior to 20.4R3-S7; 21.1 versions prior to 21.1R3-S5; 21.2 versions prior to 21.2R3-S3; 21.3 versions prior to 21.3R3-S3; 21.4 versions prior to 21.4R3-S1; 22.1 versions prior to 22.1R3; 22.2 versions prior to 22.2R2; 22.3 versions prior to 22.3R1-S1, 22.3R2. • https://supportportal.juniper.net/JSA71641 • CWE-372: Incomplete Internal State Distinction •
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 •
