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: 4.4EPSS: 0%CPEs: 16EXPL: 0CVE-2021-1423 – Cisco Aironet Access Points Arbitrary File Overwrite Vulnerability
https://notcve.org/view.php?id=CVE-2021-1423
A vulnerability in the implementation of a CLI command in Cisco Aironet Access Points (AP) could allow an authenticated, local attacker to overwrite files in the flash memory of the device. This vulnerability is due to insufficient input validation for a specific command. An attacker could exploit this vulnerability by issuing a command with crafted arguments. A successful exploit could allow the attacker to overwrite or create files with data that is already present in other files that are hosted on the affected device. Una vulnerabilidad en la implementación de un comando de CLI en Cisco Aironet Access Points (AP), podría permitir a un atacante local autenticado sobrescribir archivos en la memoria flash del dispositivo. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ap-foverwrt-HyVXvrtb • CWE-668: Exposure of Resource to Wrong Sphere •
CVSS: 6.7EPSS: 0%CPEs: 17EXPL: 0CVE-2021-1449 – Cisco Access Point Software Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-1449
A vulnerability in the boot logic of Cisco Access Points Software could allow an authenticated, local attacker to execute unsigned code at boot time. The vulnerability is due to an improper check that is performed by the area of code that manages system startup processes. An attacker could exploit this vulnerability by modifying a specific file that is stored on the system, which would allow the attacker to bypass existing protections. A successful exploit could allow the attacker to execute unsigned code at boot time and bypass the software image verification check part of the secure boot process of an affected device. Note: To exploit this vulnerability, the attacker would need to have access to the development shell (devshell) on the device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ap-privesc-wEVfp8Ud • CWE-284: Improper Access Control •
CVSS: 7.4EPSS: 0%CPEs: 13EXPL: 0CVE-2021-1439 – Cisco Aironet Access Points FlexConnect Multicast DNS Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-1439
A vulnerability in the multicast DNS (mDNS) gateway feature of Cisco Aironet Series Access Points Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation of incoming mDNS traffic. An attacker could exploit this vulnerability by sending a crafted mDNS packet to an affected device through a wireless network that is configured in FlexConnect local switching mode or through a wired network on a configured mDNS VLAN. A successful exploit could allow the attacker to cause the access point (AP) to reboot, resulting in a DoS condition. Una vulnerabilidad en la funcionalidad multicast DNS (mDNS) gateway del Software Cisco Aironet Series Access Points, podría permitir a un atacante adyacente no autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-aironet-mdns-dos-E6KwYuMx • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVSS: 7.5EPSS: 0%CPEs: 14EXPL: 0CVE-2021-1437 – Cisco Aironet Access Points FlexConnect Upgrade Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2021-1437
A vulnerability in the FlexConnect Upgrade feature of Cisco Aironet Series Access Points Software could allow an unauthenticated, remote attacker to obtain confidential information from an affected device. This vulnerability is due to an unrestricted Trivial File Transfer Protocol (TFTP) configuration. An attacker could exploit this vulnerability by sending a specific TFTP request to an affected device. A successful exploit could allow the attacker to download any file from the filesystem of the affected access point (AP). Una vulnerabilidad en la funcionalidad FlexConnect Upgrade del Software Cisco Aironet Series Access Points, podría permitir a un atacante remoto no autenticado obtenga información confidencial de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-aironet-info-disc-BfWqghj • CWE-275: Permission Issues •
