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.

CVSS: 4.7EPSS: 0%CPEs: 1EXPL: 0CVE-2021-1420 – Cisco Webex Meetings HTML Injection Vulnerability
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) •

https://notcve.org/view.php?id=CVE-2021-1351
A vulnerability in the web-based interface of Cisco Webex Meetings could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based interface of the affected service. The vulnerability is due to insufficient validation of user-supplied input by the web-based interface of the affected service. An attacker could exploit this vulnerability by persuading a user of the interface to click a maliciously crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. Una vulnerabilidad en la interfaz basada en web de Cisco Webex Meetings, podría permitir a un atacante remoto no autenticado conducir un ataque de tipo cross-site scripting (XSS) contra un usuario de la interfaz basada en web del servicio afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webex-xss-Lz6HbGCt • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') CWE-80: Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS) •
CVSS: 5.5EPSS: 0%CPEs: 8EXPL: 0CVE-2021-1372 – Cisco Webex Meetings Desktop App and Webex Productivity Tools for Windows Shared Memory Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2021-1372
A vulnerability in Cisco Webex Meetings Desktop App and Webex Productivity Tools for Windows could allow an authenticated, local attacker to gain access to sensitive information on an affected system. This vulnerability is due to the unsafe usage of shared memory by the affected software. An attacker with permissions to view system memory could exploit this vulnerability by running an application on the local system that is designed to read shared memory. A successful exploit could allow the attacker to retrieve sensitive information from the shared memory, including usernames, meeting information, or authentication tokens. Note: To exploit this vulnerability, an attacker must have valid credentials on a Microsoft Windows end-user system and must log in after another user has already authenticated with Webex on the same end-user system. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wda-pt-msh-6LWOcZ5 • CWE-202: Exposure of Sensitive Information Through Data Queries •
