CVSS: 5.0EPSS: 0%CPEs: 12EXPL: 0CVE-2021-1517 – Cisco Webex Meetings and Webex Meetings Server Multimedia Sharing Security Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2021-1517
A vulnerability in the multimedia viewer feature of Cisco Webex Meetings and Cisco Webex Meetings Server could allow an authenticated, remote attacker to bypass security protections. This vulnerability is due to unsafe handling of shared content within the multimedia viewer feature. An attacker could exploit this vulnerability by sharing a file through the multimedia viewer feature. A successful exploit could allow the attacker to bypass security protections and prevent warning dialogs from appearing before files are offered to other users. Una vulnerabilidad en la funcionalidad multimedia viewer de Cisco Webex Meetings y Cisco Webex Meetings Server, podría permitir a un atacante remoto autenticado omitir las protecciones de seguridad. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webex-multimedia-26DpqVRO • CWE-693: Protection Mechanism Failure •
CVSS: 7.8EPSS: 0%CPEs: 3EXPL: 0CVE-2021-1503 – Cisco Webex Network Recording Player and Webex Player Memory Corruption Vulnerability
https://notcve.org/view.php?id=CVE-2021-1503
A vulnerability in Cisco Webex Network Recording Player for Windows and MacOS and Cisco Webex Player for Windows and MacOS could allow an attacker to execute arbitrary code on an affected system. This vulnerability is due to insufficient validation of values in Webex recording files that are in either Advanced Recording Format (ARF) or Webex Recording Format (WRF). An attacker could exploit this vulnerability by sending a user a malicious ARF or WRF file through a link or email attachment and persuading the user to open the file with the affected software on the local system. A successful exploit could allow the attacker to execute arbitrary code on the affected system with the privileges of the targeted user.

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 •
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 •
