CVSS: 6.5EPSS: 0%CPEs: 4EXPL: 0CVE-2022-40318 – frr: denial of service by crafting a BGP OPEN message with an option of type in bgp_open_option_parse in the bgp_open.c 0xff
https://notcve.org/view.php?id=CVE-2022-40318
An issue was discovered in bgpd in FRRouting (FRR) through 8.4. By crafting a BGP OPEN message with an option of type 0xff (Extended Length from RFC 9072), attackers may cause a denial of service (assertion failure and daemon restart, or out-of-bounds read). This is possible because of inconsistent boundary checks that do not account for reading 3 bytes (instead of 2) in this 0xff case. NOTE: this behavior occurs in bgp_open_option_parse in the bgp_open.c file, a different location (with a different attack vector) relative to CVE-2022-40302. Se descubrió un problema en bgpd en FRRouting (FRR) hasta 8.4. • https://github.com/FRRouting/frr/releases https://lists.debian.org/debian-lts-announce/2023/09/msg00020.html https://www.debian.org/security/2023/dsa-5495 https://access.redhat.com/security/cve/CVE-2022-40318 https://bugzilla.redhat.com/show_bug.cgi?id=2196091 • CWE-125: Out-of-bounds Read CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2022-43681
An out-of-bounds read exists in the BGP daemon of FRRouting FRR through 8.4. When sending a malformed BGP OPEN message that ends with the option length octet (or the option length word, in case of an extended OPEN message), the FRR code reads of out of the bounds of the packet, throwing a SIGABRT signal and exiting. This results in a bgpd daemon restart, causing a Denial-of-Service condition. Existe una lectura fuera de los límites en el daemon BGP de FRRouting FRR hasta 8.4. Al enviar un mensaje BGP OPEN con formato incorrecto que termina con el octeto de longitud de la opción (o la palabra de longitud de la opción, en el caso de un mensaje OPEN extendido), el código FRR se lee fuera de los límites del paquete, lanzando una señal SIGABRT y saliendo. • https://forescout.com https://lists.debian.org/debian-lts-announce/2023/09/msg00020.html https://www.debian.org/security/2023/dsa-5495 https://access.redhat.com/security/cve/CVE-2022-43681 https://bugzilla.redhat.com/show_bug.cgi?id=2196088 • CWE-125: Out-of-bounds Read •

CVSS: 5.3EPSS: 0%CPEs: 14EXPL: 0CVE-2023-26049 – Cookie parsing of quoted values can exfiltrate values from other cookies in Eclipse Jetty
https://notcve.org/view.php?id=CVE-2023-26049
Jetty is a java based web server and servlet engine. Nonstandard cookie parsing in Jetty may allow an attacker to smuggle cookies within other cookies, or otherwise perform unintended behavior by tampering with the cookie parsing mechanism. If Jetty sees a cookie VALUE that starts with `"` (double quote), it will continue to read the cookie string until it sees a closing quote -- even if a semicolon is encountered. So, a cookie header such as: `DISPLAY_LANGUAGE="b; JSESSIONID=1337; c=d"` will be parsed as one cookie, with the name DISPLAY_LANGUAGE and a value of b; JSESSIONID=1337; c=d instead of 3 separate cookies. This has security implications because if, say, JSESSIONID is an HttpOnly cookie, and the DISPLAY_LANGUAGE cookie value is rendered on the page, an attacker can smuggle the JSESSIONID cookie into the DISPLAY_LANGUAGE cookie and thereby exfiltrate it. • https://github.com/eclipse/jetty.project/pull/9339 https://github.com/eclipse/jetty.project/pull/9352 https://github.com/eclipse/jetty.project/security/advisories/GHSA-p26g-97m4-6q7c https://lists.debian.org/debian-lts-announce/2023/09/msg00039.html https://security.netapp.com/advisory/ntap-20230526-0001 https://www.debian.org/security/2023/dsa-5507 https://www.rfc-editor.org/rfc/rfc2965 https://www.rfc-editor.org/rfc/rfc6265 https://access.redhat.com/security/cve/CVE-2023 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-1286: Improper Validation of Syntactic Correctness of Input •
