CVSS: 7.9EPSS: 0%CPEs: 30EXPL: 0CVE-2022-20855 – Cisco IOS XE Software for Embedded Wireless Controllers on Catalyst Access Points Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2022-20855
A vulnerability in the self-healing functionality of Cisco IOS XE Software for Embedded Wireless Controllers on Catalyst Access Points could allow an authenticated, local attacker to escape the restricted controller shell and execute arbitrary commands on the underlying operating system of the access point. This vulnerability is due to improper checks throughout the restart of certain system processes. An attacker could exploit this vulnerability by logging on to an affected device and executing certain CLI commands. A successful exploit could allow the attacker to execute arbitrary commands on the underlying OS as root. To successfully exploit this vulnerability, an attacker would need valid credentials for a privilege level 15 user of the wireless controller. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ewc-priv-esc-nderYLtK • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-266: Incorrect Privilege Assignment •
CVSS: 8.6EPSS: 0%CPEs: 7EXPL: 0CVE-2021-1615 – Cisco Embedded Wireless Controller Software for Catalyst Access Points Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-1615
A vulnerability in the packet processing functionality of Cisco Embedded Wireless Controller (EWC) Software for Catalyst Access Points (APs) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected AP. This vulnerability is due to insufficient buffer allocation. An attacker could exploit this vulnerability by sending crafted traffic to an affected device. A successful exploit could allow the attacker to exhaust available resources and cause a DoS condition on an affected AP, as well as a DoS condition for client traffic traversing the AP. Una vulnerabilidad en la funcionalidad packet processing de Cisco Embedded Wireless Controller (EWC) Software for Catalyst Access Points (APs) podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un AP afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-ewc-dos-g6JruHRT • CWE-410: Insufficient Resource Pool •
CVSS: 7.4EPSS: 0%CPEs: 73EXPL: 0CVE-2021-34740 – Cisco Aironet Access Points WLAN Control Protocol Packet Buffer Leak Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-34740
A vulnerability in the WLAN Control Protocol (WCP) implementation for Cisco Aironet Access Point (AP) software could allow an unauthenticated, adjacent attacker to cause a reload of an affected device, resulting in a denial of service (DoS) condition. This vulnerability is due to incorrect error handling when an affected device receives an unexpected 802.11 frame. An attacker could exploit this vulnerability by sending certain 802.11 frames over the wireless network to an interface on an affected AP. A successful exploit could allow the attacker to cause a packet buffer leak. This could eventually result in buffer allocation failures, which would trigger a reload of the affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-airo-wpa-pktleak-dos-uSTyGrL • CWE-401: Missing Release of Memory after Effective Lifetime •
CVSS: 5.3EPSS: 0%CPEs: 330EXPL: 0CVE-2020-26139 – kernel: Forwarding EAPOL from unauthenticated wifi client
https://notcve.org/view.php?id=CVE-2020-26139
An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients. Se detectó un problema en el kernel en NetBSD versión 7.1. Un punto de acceso (AP) reenvía tramas EAPOL a otros clientes aunque el remitente aún no se haya autenticado con éxito en el AP. • 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://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wifi-faf-22epcEWu https://www.arista.com/en/support/advisories-notices/security-advisories/12602-s • CWE-287: Improper Authentication CWE-829: Inclusion of Functionality from Untrusted Control Sphere •

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.
