CVE-2021-34711 – Cisco IP Phone Software Arbitrary File Read Vulnerability
https://notcve.org/view.php?id=CVE-2021-34711
A vulnerability in the debug shell of Cisco IP Phone software could allow an authenticated, local attacker to read any file on the device file system. This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by providing crafted input to a debug shell command. A successful exploit could allow the attacker to read any file on the device file system. Una vulnerabilidad en el shell de depuración del software de Cisco IP Phone podría permitir a un atacante local autenticado leer cualquier archivo del sistema de archivos del dispositivo. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ipphone-arbfileread-NPdtE2Ow • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-36: Absolute Path Traversal •
CVE-2021-33478
https://notcve.org/view.php?id=CVE-2021-33478
The TrustZone implementation in certain Broadcom MediaxChange firmware could allow an unauthenticated, physically proximate attacker to achieve arbitrary code execution in the TrustZone Trusted Execution Environment (TEE) of an affected device. This, for example, affects certain Cisco IP Phone and Wireless IP Phone products before 2021-07-07. Exploitation is possible only when the attacker can disassemble the device in order to control the voltage/current for chip pins. La implementación de TrustZone en determinados firmware de Broadcom MediaxChange, podría permitir a un atacante no autenticado y físicamente próximo lograr la ejecución de código arbitrario en el TrustZone Trusted Execution Environment (TEE) de un dispositivo afectado. Esto, por ejemplo, afecta a determinados productos Cisco IP Phone y Wireless IP Phone anteriores a 2021-07-07. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-brcm-mxc-jul2021-26LqUZUh • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
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-2020-26139 – 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 •
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 •
