https://notcve.org/view.php?id=CVE-2022-46143
Affected devices do not check the TFTP blocksize correctly. This could allow an authenticated attacker to read from an uninitialized buffer that potentially contains previously allocated data. Los dispositivos afectados no verifican correctamente el tamaño del bloque TFTP. Esto podría permitir que un atacante autenticado lea desde un búfer no inicializado que potencialmente contenga datos previamente asignados. • https://cert-portal.siemens.com/productcert/pdf/ssa-180704.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-413565.pdf https://cert-portal.siemens.com/productcert/html/ssa-413565.html https://cert-portal.siemens.com/productcert/html/ssa-180704.html • CWE-1284: Improper Validation of Specified Quantity in Input •
CVSS: 6.5EPSS: 0%CPEs: 408EXPL: 0CVE-2020-26140 – kernel: accepting plaintext data frames in protected networks
https://notcve.org/view.php?id=CVE-2020-26140
An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The WEP, WPA, WPA2, and WPA3 implementations accept plaintext frames in a protected Wi-Fi network. An adversary can abuse this to inject arbitrary data frames independent of the network configuration. Se detectó un problema en el controlador ALFA de Windows 10 versión 6.1316.1209 para AWUS036H. Las implementaciones WEP, WPA, WPA2 y WPA3 aceptan tramas de texto plano en una red Wi-Fi protegida. • 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://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wifi-faf-22epcEWu https://www.arista.com/en/support/advisories-notices/security-advisories/12602-security-advisory-63 https://www.fragattacks.com https://access.redhat.com/security/cve/CVE-2020-26140 https://bugzilla.redhat.com/show&# • CWE-327: Use of a Broken or Risky Cryptographic Algorithm CWE-346: Origin Validation Error •
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 •
