CVE-2020-1676 – Juniper Networks Mist Cloud UI: SAML authentication response handling vulnerability.
https://notcve.org/view.php?id=CVE-2020-1676
When SAML authentication is enabled, Juniper Networks Mist Cloud UI might incorrectly handle SAML responses, allowing a remote attacker to modify a valid SAML response without invalidating its cryptographic signature to bypass SAML authentication security controls. This issue affects all Juniper Networks Mist Cloud UI versions prior to September 2 2020. Cuando la autenticación SAML está habilitada, Juniper Networks Mist Cloud UI puede manejar incorrectamente las respuestas SAML, permitiendo a un atacante remoto modificar una respuesta SAML válida sin invalidar su firma criptográfica para omitir los controles de seguridad de autenticación SAML. Este problema afecta a todas las versiones de Juniper Networks Mist Cloud UI anteriores al 2 de septiembre de 2020 • https://kb.juniper.net/JSA11072 • CWE-20: Improper Input Validation •
CVE-2020-1675 – Juniper Networks Mist Cloud UI: SAML authentication certificate vulnerability.
https://notcve.org/view.php?id=CVE-2020-1675
When Security Assertion Markup Language (SAML) authentication is enabled, Juniper Networks Mist Cloud UI might incorrectly process invalid authentication certificates which could allow a malicious network-based user to access unauthorized data. This issue affects all Juniper Networks Mist Cloud UI versions prior to September 2 2020. Cuando la autenticación de Security Assertion Markup Language (SAML) está habilitada, Juniper Networks Mist Cloud UI puede procesar incorrectamente los certificados de autenticación no válidos, lo que podría permitir a un usuario malicioso de la red acceder a datos no autorizados. Este problema afecta a todas las versiones de Juniper Networks Mist Cloud UI anteriores al 2 de septiembre de 2020 • https://kb.juniper.net/JSA11072 • CWE-295: Improper Certificate Validation CWE-299: Improper Check for Certificate Revocation •
CVE-2020-1673 – Junos OS: Reflected Cross-site Scripting vulnerability in J-Web and web based (HTTP/HTTPS) services
https://notcve.org/view.php?id=CVE-2020-1673
Insufficient Cross-Site Scripting (XSS) protection in Juniper Networks J-Web and web based (HTTP/HTTPS) services allows an unauthenticated attacker to hijack the target user's HTTP/HTTPS session and perform administrative actions on the Junos device as the targeted user. This issue only affects Juniper Networks Junos OS devices with HTTP/HTTPS services enabled such as J-Web, Web Authentication, Dynamic-VPN (DVPN), Firewall Authentication Pass-Through with Web-Redirect, and Zero Touch Provisioning (ZTP). Junos OS devices with HTTP/HTTPS services disabled are not affected. If HTTP/HTTPS services are enabled, the following command will show the httpd processes: user@device> show system processes | match http 5260 - S 0:00.13 /usr/sbin/httpd-gk -N 5797 - I 0:00.10 /usr/sbin/httpd --config /jail/var/etc/httpd.conf In order to successfully exploit this vulnerability, the attacker needs to convince the device administrator to take action such as clicking the crafted URL sent via phishing email or convince the administrator to input data in the browser console. This issue affects Juniper Networks Junos OS: 18.1 versions prior to 18.1R3-S1; 18.2 versions prior to 18.2R3-S5; 18.3 versions prior to 18.3R2-S4, 18.3R3-S2; 18.4 versions prior to 18.4R2-S5, 18.4R3-S2; 19.1 versions prior to 19.1R2-S2, 19.1R3-S1; 19.2 versions prior to 19.2R1-S5, 19.2R2; 19.3 versions prior to 19.3R2-S4, 19.3R3; 19.4 versions prior to 19.4R1-S3, 19.4R2; 20.1 versions prior to 20.1R1-S2, 20.1R2. • https://kb.juniper.net/JSA11070 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVE-2020-1672 – Junos OS: jdhcpd process crash when processing a specific DHCPDv6 packet in DHCPv6 relay configuration.
https://notcve.org/view.php?id=CVE-2020-1672
On Juniper Networks Junos OS devices configured with DHCPv6 relay enabled, receipt of a specific DHCPv6 packet might crash the jdhcpd daemon. The jdhcpd daemon automatically restarts without intervention, but continuous receipt of specific crafted DHCP messages will repeatedly crash jdhcpd, leading to an extended Denial of Service (DoS) condition. Only DHCPv6 packet can trigger this issue. DHCPv4 packet cannot trigger this issue. This issue affects Juniper Networks Junos OS: 17.3 versions prior to 17.3R3-S9; 17.4 versions prior to 17.4R2-S11, 17.4R3-S2, 17.4R3-S3; 18.1 versions prior to 18.1R3-S11; 18.2 versions prior to 18.2R3-S5; 18.3 versions prior to 18.3R2-S4, 18.3R3-S3; 18.4 versions prior to 18.4R2-S5, 18.4R3-S4; 19.1 versions prior to 19.1R2-S2, 19.1R3-S2; 19.2 versions prior to 19.2R1-S5, 19.2R2-S1, 19.2R3; 19.3 versions prior to 19.3R2-S4, 19.3R2-S4, 19.3R3; 19.4 versions prior to 19.4R1-S3, 19.4R2-S1, 19.4R3; 20.1 versions prior to 20.1R1-S3, 20.1R2. • https://kb.juniper.net/JSA11069 • CWE-20: Improper Input Validation •
CVE-2020-1671 – Junos OS: Receipt of malformed DHCPv6 packets causes jdhcpd to crash.
https://notcve.org/view.php?id=CVE-2020-1671
On Juniper Networks Junos OS platforms configured as DHCPv6 local server or DHCPv6 Relay Agent, Juniper Networks Dynamic Host Configuration Protocol Daemon (JDHCPD) process might crash with a core dump if a malformed DHCPv6 packet is received, resulting with the restart of the daemon. This issue only affects DHCPv6, it does not affect DHCPv4. This issue affects: Juniper Networks Junos OS 17.4 versions prior to 17.4R2-S12, 17.4R3-S3; 18.1 versions prior to 18.1R3-S11; 18.2 versions prior to 18.2R3-S6; 18.2X75 versions prior to 18.2X75-D65; 18.3 versions prior to 18.3R2-S4, 18.3R3-S3; 18.4 versions prior to 18.4R2-S5, 18.4R3-S4; 19.1 versions prior to 19.1R3-S2; 19.2 versions prior to 19.2R1-S5, 19.2R3; 19.2 version 19.2R2 and later versions; 19.3 versions prior to 19.3R2-S4, 19.3R3; 19.4 versions prior to 19.4R1-S3, 19.4R2-S2, 19.4R3; 20.1 versions prior to 20.1R1-S3, 20.1R2; This issue does not affect Juniper Networks Junos OS prior to 17.4R1. En las plataformas Juniper Networks Junos OS configuradas como servidor local DHCPv6 o DHCPv6 Relay Agent, el proceso Juniper Networks Dynamic Host Configuration Protocol Daemon (JDHCPD) puede bloquearse con un volcado del núcleo si un paquete DHCPv6 malformado es recibido, resultando en el reinicio del demonio. Este problema solo afecta a DHCPv6, no afecta a DHCPv4. • https://kb.juniper.net/JSA11068 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
