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: 7.5EPSS: 0%CPEs: 4EXPL: 0CVE-2018-0026 – Junos OS: Stateless IP firewall filter rules stop working as expected after reboot or upgrade
https://notcve.org/view.php?id=CVE-2018-0026
After Junos OS device reboot or upgrade, the stateless firewall filter configuration may not take effect. This issue can be verified by running the command: user@re0> show interfaces <interface_name> extensive | match filters" CAM destination filters: 0, CAM source filters: 0 Note: when the issue occurs, it does not show the applied firewall filter. The correct output should show the applied firewall filter, for example: user@re0> show interfaces <interface_name> extensive | match filters" CAM destination filters: 0, CAM source filters: 0 Input Filters: FIREWAL_FILTER_NAME-<interface_name> This issue affects firewall filters for every address family. Affected releases are Juniper Networks Junos OS: 15.1R4, 15.1R5, 15.1R6 and SRs based on these MRs. 15.1X8 versions prior to 15.1X8.3. Tras un reinicio o actualización del dispositivo Junos OS, la configuración del filtro del firewall sin estado podría no surtir efecto. • http://www.securityfocus.com/bid/104720 http://www.securitytracker.com/id/1041315 https://kb.juniper.net/JSA10859 •
