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 •
CVSS: 3.1EPSS: 0%CPEs: 338EXPL: 1CVE-2020-24587 – kernel: Reassembling fragments encrypted under different keys
https://notcve.org/view.php?id=CVE-2020-24587
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed. El estándar 802.11 que sustenta a Wi-Fi Protected Access (WPA, WPA2, y WPA3) y Wired Equivalent Privacy (WEP) no requiere que todos los fragmentos de una trama estén cifrados con la misma clave. Un adversario puede abusar de esto para descifrar fragmentos seleccionados cuando otro dispositivo envía tramas fragmentadas y la clave de cifrado WEP, CCMP o GCMP es periódicamente renovada A flaw was found in the Linux kernel's WiFi implementation. An attacker within the wireless range can abuse a logic flaw in the WiFi implementation by reassembling packets from multiple fragments under different keys, treating them as valid. • http://www.openwall.com/lists/oss-security/2021/05/11/12 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://www.arista.com/en/support/advisories-notices/security-advisories/12 • CWE-327: Use of a Broken or Risky Cryptographic Algorithm CWE-345: Insufficient Verification of Data Authenticity •
CVSS: 4.3EPSS: 0%CPEs: 1EXPL: 0CVE-2021-1467 – Cisco Webex Meetings for Android Avatar Modification Vulnerability
https://notcve.org/view.php?id=CVE-2021-1467
A vulnerability in Cisco Webex Meetings for Android could allow an authenticated, remote attacker to modify the avatar of another user. This vulnerability is due to improper authorization checks. An attacker could exploit this vulnerability by sending a crafted request to the Cisco Webex Meetings client of a targeted user of a meeting in which they are both participants. A successful exploit could allow the attacker to modify the avatar of the targeted user.

https://notcve.org/view.php?id=CVE-2021-1420
A vulnerability in certain web pages of Cisco Webex Meetings could allow an unauthenticated, remote attacker to modify a web page in the context of a user's browser. The vulnerability is due to improper checks on parameter values in affected pages. An attacker could exploit this vulnerability by persuading a user to follow a crafted link that is designed to pass HTML code into an affected parameter. A successful exploit could allow the attacker to alter the contents of a web page to redirect the user to potentially malicious websites, or the attacker could use this vulnerability to conduct further client-side attacks. Una vulnerabilidad en determinadas páginas web de Cisco Webex Meetings, podría permitir a un atacante remoto no autenticado modificar una página web en el contexto del navegador de un usuario. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webex-VObwRKWV • CWE-80: Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS) •
