An issue was discovered in Embedthis GoAhead before 4.0.1 and Appweb before 7.0.2. The server mishandles some HTTP request fields associated with time, which results in a NULL pointer dereference, as demonstrated by If-Modified-Since or If-Unmodified-Since with a month greater than 11. Se ha descubierto un problema en Embedthis GoAhead en versiones anteriores a la 4.0.1 y Appweb anteriores a la 7.0.2. El servidor maneja incorrectamente algunos campos request HTTP asociados con time, lo que resulta en una desreferencia de puntero NULL, tal y como queda demostrado con If-Modified-Since o If-Unmodified-Since con mes mayor a 11. • https://github.com/embedthis/appweb/commit/66067ae6d1fa08b37a270e7dc1821df52ed2daef https://github.com/embedthis/appweb/issues/605 https://github.com/embedthis/goahead/issues/264 https://supportportal.juniper.net/s/article/2019-07-Security-Bulletin-Junos-OS-J-Web-Denial-of-Service-due-to-multiple-vulnerabilities-in-Embedthis-Appweb-Server https://supportportal.juniper.net/s/article/2021-07-Security-Bulletin-Junos-OS-Multiple-J-Web-vulnerabilities-resolved • CWE-476: NULL Pointer Dereference •

An issue was discovered in Embedthis GoAhead before 4.0.1 and Appweb before 7.0.2. An HTTP POST request with a specially crafted "Host" header field may cause a NULL pointer dereference and thus cause a denial of service, as demonstrated by the lack of a trailing ']' character in an IPv6 address. Se ha descubierto un problema en Embedthis GoAhead en versiones anteriores a la 4.0.1 y Appweb anteriores a la 7.0.2. Una petición HTTP POST con un campo de cabecera "Host" especialmente manipulado puede causar una desreferencia de puntero NULL y, por lo tanto, una denegación de servicio, tal y como queda demostrado con la falta de un carácter posterior ']' en una dirección IPv6. • https://github.com/embedthis/appweb/commit/16e6979c82297d5fc4f8661e7ada975f51e4dfa9 https://github.com/embedthis/appweb/issues/605 https://github.com/embedthis/goahead/issues/264 https://supportportal.juniper.net/s/article/2021-07-Security-Bulletin-Junos-OS-Multiple-J-Web-vulnerabilities-resolved?language=en_US • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2018-0024
An Improper Privilege Management vulnerability in a shell session of Juniper Networks Junos OS allows an authenticated unprivileged attacker to gain full control of the system. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D45 on SRX Series; 12.3X48 versions prior to 12.3X48-D20 on SRX Series; 12.3 versions prior to 12.3R11 on EX Series; 14.1X53 versions prior to 14.1X53-D30 on EX2200/VC, EX3200, EX3300/VC, EX4200, EX4300, EX4550/VC, EX4600, EX6200, EX8200/VC (XRE), QFX3500, QFX3600, QFX5100;; 15.1X49 versions prior to 15.1X49-D20 on SRX Series. Una vulnerabilidad de gestión incorrecta de privilegios en una sesión shell de Juniper Networks Junos OS permite que un atacante autenticado sin privilegios obtenga el control total del sistema. Las versiones afectadas son Juniper Networks Junos OS: 12.1X46 en versiones anteriores a la 12.1X46-D45 en SRX Series; 12.3X48 en versiones anteriores a la 12.3X48-D20 en SRX Series; 12.3 en versiones anteriores a la 12.3R11 en EX Series; 14.1X53 en versiones anteriores a la 14.1X53-D30 en EX2200/VC, EX3200, EX3300/VC, EX4200, EX4300, EX4550/VC, EX4600, EX6200, EX8200/VC (XRE), QFX3500, QFX3600, QFX5100 y 15.1X49 en versiones anteriores a la 15.1X49-D20 en SRX Series. • http://www.securityfocus.com/bid/104718 http://www.securitytracker.com/id/1041314 https://kb.juniper.net/JSA10857 • CWE-269: Improper Privilege Management •
CVSS: 8.1EPSS: 0%CPEs: 82EXPL: 0CVE-2018-0025 – Junos OS: SRX Series: Credentials exposed when using HTTP and HTTPS Firewall Pass-through User Authentication
https://notcve.org/view.php?id=CVE-2018-0025
When an SRX Series device is configured to use HTTP/HTTPS pass-through authentication services, a client sending authentication credentials in the initial HTTP/HTTPS session is at risk that these credentials may be captured during follow-on HTTP/HTTPS requests by a malicious actor through a man-in-the-middle attack or by authentic servers subverted by malicious actors. FTP, and Telnet pass-through authentication services are not affected. Affected releases are Juniper Networks SRX Series: 12.1X46 versions prior to 12.1X46-D67 on SRX Series; 12.3X48 versions prior to 12.3X48-D25 on SRX Series; 15.1X49 versions prior to 15.1X49-D35 on SRX Series. Cuando un dispositivo SRX Series está configurado para emplear los servicios de autenticación pass-through HTTP/HTTPS, un cliente que envía credenciales de autenticación en la sesión inicial HTTP/HTTPS está en riesgo de que estas credenciales puedan ser capturadas durante peticiones HTTP/HTTPS follow-on por parte de un actor malicioso mediante un ataque Man-in-the-Middle (MitM) o por medio de servidores auténticos subvertidos por actores maliciosos. Los servicios de autenticación pass-through FTP y Telnet no se han visto afectados. • http://www.securityfocus.com/bid/104719 http://www.securitytracker.com/id/1041316 https://kb.juniper.net/JSA10858 https://www.juniper.net/documentation/en_US/junos/topics/concept/firewall-user-authentication-pass-through-understanding.html https://www.juniper.net/documentation/en_US/junos/topics/example/firewall-user-authentication-pass-through-configuring-cli.html https://www.juniper.net/documentation/en_US/junos/topics/example/security-https-traffic-to-trigger-pass-through-authentication-configuring.html • CWE-300: Channel Accessible by Non-Endpoint CWE-319: Cleartext Transmission of Sensitive Information •
CVSS: 5.9EPSS: 0%CPEs: 181EXPL: 0CVE-2018-0031 – Junos OS: Receipt of specially crafted UDP packets over MPLS may bypass stateless IP firewall rules
https://notcve.org/view.php?id=CVE-2018-0031
Receipt of specially crafted UDP/IP packets over MPLS may be able to bypass a stateless firewall filter. The crafted UDP packets must be encapsulated and meet a very specific packet format to be classified in a way that bypasses IP firewall filter rules. The packets themselves do not cause a service interruption (e.g. RPD crash), but receipt of a high rate of UDP packets may be able to contribute to a denial of service attack. This issue only affects processing of transit UDP/IP packets over MPLS, received on an interface with MPLS enabled. • http://www.securitytracker.com/id/1041326 https://kb.juniper.net/JSA10865 • CWE-400: Uncontrolled Resource Consumption •
