CVSS: 3.7EPSS: 0%CPEs: 2EXPL: 0CVE-2024-1410 – Unbounded storage of information related to connection ID retirement, in quiche
https://notcve.org/view.php?id=CVE-2024-1410
Cloudflare quiche was discovered to be vulnerable to unbounded storage of information related to connection ID retirement, which could lead to excessive resource consumption. Each QUIC connection possesses a set of connection Identifiers (IDs); see RFC 9000 Section 5.1 https://datatracker.ietf.org/doc/html/rfc9000#section-5.1 . Endpoints declare the number of active connection IDs they are willing to support using the active_connection_id_limit transport parameter. The peer can create new IDs using a NEW_CONNECTION_ID frame but must stay within the active ID limit. This is done by retirement of old IDs, the endpoint sends NEW_CONNECTION_ID includes a value in the retire_prior_to field, which elicits a RETIRE_CONNECTION_ID frame as confirmation. • https://github.com/cloudflare/quiche/security/advisories/GHSA-xhg9-xwch-vr7x • CWE-400: Uncontrolled Resource Consumption •
CVSS: 5.9EPSS: 0%CPEs: 2EXPL: 0CVE-2024-1765 – Unlimited resource allocation by QUIC CRYPTO frames flooding in quiche
https://notcve.org/view.php?id=CVE-2024-1765
Cloudflare Quiche (through version 0.19.1/0.20.0) was affected by an unlimited resource allocation vulnerability causing rapid increase of memory usage of the system running quiche server or client. A remote attacker could take advantage of this vulnerability by repeatedly sending an unlimited number of 1-RTT CRYPTO frames after previously completing the QUIC handshake. Exploitation was possible for the duration of the connection which could be extended by the attacker. quiche 0.19.2 and 0.20.1 are the earliest versions containing the fix for this issue. Cloudflare Quiche (hasta la versión 0.19.1/0.20.0) se vio afectado por una vulnerabilidad de asignación de recursos ilimitada que provocó un rápido aumento del uso de memoria del sistema que ejecuta el servidor o cliente quiche. Un atacante remoto podría aprovechar esta vulnerabilidad enviando repetidamente un número ilimitado de fotogramas 1-RTT CRYPTO después de completar previamente el protocolo de enlace QUIC. La explotación era posible mientras durara la conexión, que el atacante podía ampliar. quiche 0.19.2 y 0.20.1 son las primeras versiones que contienen la solución para este problema. • https://github.com/cloudflare/quiche/security/advisories/GHSA-78wx-jg4j-5j6g • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 5.3EPSS: 0%CPEs: 1EXPL: 0CVE-2023-6193 – Unbounded queuing of path validation messages in cloudflare-quiche
https://notcve.org/view.php?id=CVE-2023-6193
quiche v. 0.15.0 through 0.19.0 was discovered to be vulnerable to unbounded queuing of path validation messages, which could lead to excessive resource consumption. QUIC path validation (RFC 9000 Section 8.2) requires that the recipient of a PATH_CHALLENGE frame responds by sending a PATH_RESPONSE. An unauthenticated remote attacker can exploit the vulnerability by sending PATH_CHALLENGE frames and manipulating the connection (e.g. by restricting the peer's congestion window size) so that PATH_RESPONSE frames can only be sent at the slower rate than they are received; leading to storage of path validation data in an unbounded queue. Quiche versions greater than 0.19.0 address this problem. Se descubrió que quiche v. 0.15.0 a 0.19.0 era vulnerable a colas ilimitadas de mensajes de validación de ruta, lo que podría provocar un consumo excesivo de recursos. La validación de ruta QUIC (RFC 9000 Sección 8.2) requiere que el destinatario de una trama PATH_CHALLENGE responda enviando una PATH_RESPONSE. Un atacante remoto no autenticado puede explotar la vulnerabilidad enviando tramas PATH_CHALLENGE y manipulando la conexión (por ejemplo, restringiendo el tamaño de la ventana de congestión del par) de modo que las tramas PATH_RESPONSE sólo puedan enviarse a una velocidad más lenta de la que se reciben; lo que lleva al almacenamiento de datos de validación de ruta en una cola ilimitada. • https://datatracker.ietf.org/doc/html/rfc9000#section-8.2 https://github.com/cloudflare/quiche/security/advisories/GHSA-w3vp-jw9m-f9pm • CWE-400: Uncontrolled Resource Consumption •
