CVE-2020-26141 – kernel: not verifying TKIP MIC of fragmented frames
https://notcve.org/view.php?id=CVE-2020-26141
An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data-confidentiality protocol. Se detectó un problema en el controlador ALFA de Windows 10 versión 6.1316.1209 para AWUS036H. La implementación de Wi-Fi no verifica la Comprobación de Integridad del Mensaje (autenticidad) de las tramas TKIP fragmentadas. • 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-2020-26141 https://bugzilla.redhat.com/show • CWE-354: Improper Validation of Integrity Check Value CWE-863: Incorrect Authorization •
CVE-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 •
