CVSS: 4.3EPSS: 0%CPEs: 385EXPL: 1CVE-2020-24588 – kernel: wifi frame payload being parsed incorrectly as an L2 frame
https://notcve.org/view.php?id=CVE-2020-24588
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated. Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets. El estándar 802.11 que sustenta a Wi-Fi Protected Access (WPA, WPA2, y WPA3) y Wired Equivalent Privacy (WEP) no requiere que el flag A-MSDU en el campo de encabezado QoS de texto plano esté autenticada. Contra dispositivos que admiten la recepción de tramas A-MSDU que no son SSP (que es obligatorio como parte de 802.11n), un adversario puede abusar de esto para inyectar paquetes de red arbitrarios A flaw was found in the Linux kernels wifi implementation. An attacker within wireless broadcast range can inject custom data into the wireless communication circumventing checks on the data. • http://www.openwall.com/lists/oss-security/2021/05/11/12 https://cert-portal.siemens.com/productcert/pdf/ssa-913875.pdf https://github.com/vanhoefm/fragattacks/blob/master/SUMMARY.md https://lists.debian.org/debian-lts-announce/2021/06/msg00019.html https://lists.debian.org/debian-lts-announce/2021/06/msg00020.html https://lists.debian.org/debian-lts-announce/2023/04/msg00002.html https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wifi-faf-22epcEWu https: • CWE-20: Improper Input Validation CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
