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 •
CVSS: 5.9EPSS: 0%CPEs: 262EXPL: 0CVE-2018-0034 – Junos OS: A malicious crafted IPv6 DHCP packet may cause the JDHCPD daemon to core
https://notcve.org/view.php?id=CVE-2018-0034
A Denial of Service vulnerability exists in the Juniper Networks Junos OS JDHCPD daemon which allows an attacker to core the JDHCPD daemon by sending a crafted IPv6 packet to the system. This issue is limited to systems which receives IPv6 DHCP packets on a system configured for DHCP processing using the JDHCPD daemon. This issue does not affect IPv4 DHCP packet processing. Affected releases are Juniper Networks Junos OS: 12.3 versions prior to 12.3R12-S10 on EX Series; 12.3X48 versions prior to 12.3X48-D70 on SRX Series; 14.1X53 versions prior to 14.1X53-D47 on EX2200/VC, EX3200, EX3300/VC, EX4200, EX4300, EX4550/VC, EX4600, EX6200, EX8200/VC (XRE), QFX3500, QFX3600, QFX5100; 14.1X53 versions prior to 14.1X53-D130 on QFabric; 15.1 versions prior to 15.1R4-S9, 15.1R6-S6, 15.1R7; 15.1X49 versions prior to 15.1X49-D140 on SRX Series; 15.1X53 versions prior to 15.1X53-D67 on QFX10000 Series; 15.1X53 versions prior to 15.1X53-D233 on QFX5110, QFX5200; 15.1X53 versions prior to 15.1X53-D471 on NFX 150, NFX 250; 16.1 versions prior to 16.1R3-S9, 16.1R4-S8, 16.1R5-S4, 16.1R6-S3, 16.1R7; 16.2 versions prior to 16.2R2-S5, 16.2R3; 17.1 versions prior to 17.1R1-S7, 17.1R2-S7, 17.1R3; 17.2 versions prior to 17.2R1-S6, 17.2R2-S4, 17.2R3; 17.3 versions prior to 17.3R1-S4, 17.3R2-S2, 17.3R3; 17.4 versions prior to 17.4R1-S3, 17.4R2. Existe una vulnerabilidad de denegación de servicio (DoS) en el demonio JDHCPD en Junos OS, de Juniper Networks, que permite que un atacante elimine el núcleo del demonio JDHCPD mediante el envío de un paquete IPv6 manipulado al sistema. • http://www.securitytracker.com/id/1041338 https://apps.juniper.net/feature-explorer/search.html#q=dhcp https://kb.juniper.net/JSA10868 • CWE-20: Improper Input Validation •
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 •
CVSS: 6.5EPSS: 0%CPEs: 141EXPL: 0CVE-2018-0029 – Junos OS: Kernel crash (vmcore) during broadcast storm after enabling 'monitor traffic interface fxp0'
https://notcve.org/view.php?id=CVE-2018-0029
While experiencing a broadcast storm, placing the fxp0 interface into promiscuous mode via the 'monitor traffic interface fxp0' can cause the system to crash and restart (vmcore). This issue only affects Junos OS 15.1 and later releases, and affects both single core and multi-core REs. Releases prior to Junos OS 15.1 are unaffected by this vulnerability. Affected releases are Juniper Networks Junos OS: 15.1 versions prior to 15.1F6-S11, 15.1R4-S9, 15.1R6-S6, 15.1R7; 15.1X49 versions prior to 15.1X49-D140; 15.1X53 versions prior to 15.1X53-D59 on EX2300/EX3400; 15.1X53 versions prior to 15.1X53-D67 on QFX10K; 15.1X53 versions prior to 15.1X53-D233 on QFX5200/QFX5110; 15.1X53 versions prior to 15.1X53-D471, 15.1X53-D490 on NFX; 16.1 versions prior to 16.1R3-S8, 16.1R5-S4, 16.1R6-S1, 16.1R7; 16.2 versions prior to 16.2R1-S6, 16.2R2-S5, 16.2R3; 17.1 versions prior to 17.1R1-S7, 17.1R2-S7, 17.1R3; 17.2 versions prior to 17.2R1-S6, 17.2R2-S4, 17.2R3; 17.2X75 versions prior to 17.2X75-D90, 17.2X75-D110; 17.3 versions prior to 17.3R1-S4, 17.3R2; 17.4 versions prior to 17.4R1-S3, 17.4R2. Al experimentar una "tormenta de transmisiones" (broadcast storm), la colocación de la interfaz fxp0 en modo promiscuo mediante la "interfaz fxp0 de tráfico de monitorización" puede provocar que el sistema se cierre inesperadamente y se reinicie (vmcore). • http://www.securitytracker.com/id/1041319 https://kb.juniper.net/JSA10863 • CWE-400: Uncontrolled Resource Consumption •
