CVSS: 7.5EPSS: 83%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 •
CVSS: 7.5EPSS: 0%CPEs: 4EXPL: 0CVE-2023-33953 – Denial-of-Service in gRPC
https://notcve.org/view.php?id=CVE-2023-33953
gRPC contains a vulnerability that allows hpack table accounting errors could lead to unwanted disconnects between clients and servers in exceptional cases/ Three vectors were found that allow the following DOS attacks: - Unbounded memory buffering in the HPACK parser - Unbounded CPU consumption in the HPACK parser The unbounded CPU consumption is down to a copy that occurred per-input-block in the parser, and because that could be unbounded due to the memory copy bug we end up with an O(n^2) parsing loop, with n selected by the client. The unbounded memory buffering bugs: - The header size limit check was behind the string reading code, so we needed to first buffer up to a 4 gigabyte string before rejecting it as longer than 8 or 16kb. - HPACK varints have an encoding quirk whereby an infinite number of 0’s can be added at the start of an integer. gRPC’s hpack parser needed to read all of them before concluding a parse. - gRPC’s metadata overflow check was performed per frame, so that the following sequence of frames could cause infinite buffering: HEADERS: containing a: 1 CONTINUATION: containing a: 2 CONTINUATION: containing a: 3 etc… • https://cloud.google.com/support/bulletins#gcp-2023-022 • CWE-770: Allocation of Resources Without Limits or Throttling CWE-789: Memory Allocation with Excessive Size Value CWE-834: Excessive Iteration •
CVSS: 5.3EPSS: 0%CPEs: 3EXPL: 0CVE-2023-32732 – Denial-of-Service in gRPC
https://notcve.org/view.php?id=CVE-2023-32732
gRPC contains a vulnerability whereby a client can cause a termination of connection between a HTTP2 proxy and a gRPC server: a base64 encoding error for `-bin` suffixed headers will result in a disconnection by the gRPC server, but is typically allowed by HTTP2 proxies. We recommend upgrading beyond the commit in https://github.com/grpc/grpc/pull/32309 https://www.google.com/url gRPC contiene una vulnerabilidad por la que un cliente puede provocar la finalización de la conexión entre un proxy HTTP2 y un servidor gRPC. Un error de codificación en base64 para cabeceras con sufijo "-bin" provocará la desconexión por parte del servidor gRPC, pero suele estar permitido por los proxies HTTP2. Se recomienda actualizar más allá del commit "https://github.com/grpc/grpc/pull/32309". • https://github.com/grpc/grpc/pull/32309 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/37IDNVY5AWVH7JDMM2SDTL24ZPPZJNSY https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/VWE44J5FG7THHL7XVEVTNIGEYBNKJBLL • CWE-440: Expected Behavior Violation •
