CVSS: 7.7EPSS: 0%CPEs: 1EXPL: 0CVE-2023-39331 – nodejs: permission model improperly protects against path traversal
https://notcve.org/view.php?id=CVE-2023-39331
A previously disclosed vulnerability (CVE-2023-30584) was patched insufficiently in commit 205f1e6. The new path traversal vulnerability arises because the implementation does not protect itself against the application overwriting built-in utility functions with user-defined implementations. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js. Una vulnerabilidad previamente revelada (CVE-2023-30584) no se parchó suficientemente en el commit 205f1e6. La nueva vulnerabilidad de path traversal surge porque la implementación no se protege a sí misma contra la sobrescritura de funciones de utilidad integradas con implementaciones definidas por el usuario. Tenga en cuenta que en el momento en que se emitió este CVE, el modelo de permiso es una característica experimental de Node.js. • https://hackerone.com/reports/2092852 https://security.netapp.com/advisory/ntap-20231116-0009 https://access.redhat.com/security/cve/CVE-2023-39331 https://bugzilla.redhat.com/show_bug.cgi?id=2244413 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 7.5EPSS: 0%CPEs: 5EXPL: 0CVE-2023-38552 – nodejs: integrity checks according to policies can be circumvented
https://notcve.org/view.php?id=CVE-2023-38552
When the Node.js policy feature checks the integrity of a resource against a trusted manifest, the application can intercept the operation and return a forged checksum to the node's policy implementation, thus effectively disabling the integrity check. Impacts: This vulnerability affects all users using the experimental policy mechanism in all active release lines: 18.x and, 20.x. Please note that at the time this CVE was issued, the policy mechanism is an experimental feature of Node.js. Cuando la función de política de Node.js verifica la integridad de un recurso con un manifiesto confiable, la aplicación puede interceptar la operación y devolver una suma de verificación falsificada a la implementación de la política del nodo, deshabilitando así efectivamente la verificación de integridad. Impactos: esta vulnerabilidad afecta a todos los usuarios que utilizan el mecanismo de política experimental en todas las líneas de versiones activas: 18.x y 20.x. Tenga en cuenta que en el momento en que se emitió este CVE, el mecanismo de política era una característica experimental de Node.js. When the Node.js policy feature checks the integrity of a resource against a trusted manifest, the application can intercept the operation and return a forged checksum to node's policy implementation, thus effectively disabling the integrity check. • https://hackerone.com/reports/2094235 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/3N4NJ7FR4X4FPZUGNTQAPSTVB2HB2Y4A https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/E72T67UPDRXHIDLO3OROR25YAMN4GGW5 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/FNA62Q767CFAFHBCDKYNPBMZWB7TWYVU https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/HT7T2R4MQKLIF4ODV4BDLPARWFPCJ5CZ https://lists.fedoraproject. • CWE-345: Insufficient Verification of Data Authenticity CWE-354: Improper Validation of Integrity Check Value •
CVSS: 9.8EPSS: 0%CPEs: 2EXPL: 0CVE-2023-39332 – nodejs: path traversal through path stored in Uint8Array
https://notcve.org/view.php?id=CVE-2023-39332
Various `node:fs` functions allow specifying paths as either strings or `Uint8Array` objects. In Node.js environments, the `Buffer` class extends the `Uint8Array` class. Node.js prevents path traversal through strings (see CVE-2023-30584) and `Buffer` objects (see CVE-2023-32004), but not through non-`Buffer` `Uint8Array` objects. This is distinct from CVE-2023-32004 which only referred to `Buffer` objects. However, the vulnerability follows the same pattern using `Uint8Array` instead of `Buffer`. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js. Varias funciones `node:fs` permiten especificar rutas como cadenas u objetos `Uint8Array`. • https://hackerone.com/reports/2199818 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/3N4NJ7FR4X4FPZUGNTQAPSTVB2HB2Y4A https://security.netapp.com/advisory/ntap-20231116-0009 https://access.redhat.com/security/cve/CVE-2023-39332 https://bugzilla.redhat.com/show_bug.cgi?id=2244414 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 7.5EPSS: 81%CPEs: 444EXPL: 7CVE-2023-44487 – HTTP/2 Rapid Reset Attack Vulnerability
https://notcve.org/view.php?id=CVE-2023-44487
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. El protocolo HTTP/2 permite una denegación de servicio (consumo de recursos del servidor) porque la cancelación de solicitudes puede restablecer muchas transmisiones rápidamente, como se explotó en la naturaleza entre agosto y octubre de 2023. A flaw was found in handling multiplexed streams in the HTTP/2 protocol. A client can repeatedly make a request for a new multiplex stream and immediately send an RST_STREAM frame to cancel it. This creates extra work for the server setting up and tearing down the streams while not hitting any server-side limit for the maximum number of active streams per connection, resulting in a denial of service due to server resource consumption. • https://github.com/imabee101/CVE-2023-44487 https://github.com/studiogangster/CVE-2023-44487 https://github.com/bcdannyboy/CVE-2023-44487 https://github.com/sigridou/CVE-2023-44487- https://github.com/ByteHackr/CVE-2023-44487 https://github.com/ReToCode/golang-CVE-2023-44487 http://www.openwall.com/lists/oss-security/2023/10/13/4 http://www.openwall.com/lists/oss-security/2023/10/13/9 http://www.openwall.com/lists/oss-security/2023/10/18/4 http://www. • CWE-400: Uncontrolled Resource Consumption •
