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: 8.1EPSS: 0%CPEs: 51EXPL: 0CVE-2020-3261 – Cisco Mobility Express Software Cross-Site Request Forgery Vulnerability
https://notcve.org/view.php?id=CVE-2020-3261
A vulnerability in the web-based management interface of Cisco Mobility Express Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system. The vulnerability is due to insufficient CSRF protections for the web-based management interface on an affected device. An attacker could exploit this vulnerability by persuading a user with an active session on an affected device to follow a malicious link. A successful exploit could allow the attacker to perform arbitrary actions, including modifying the configuration, with the privilege level of the user.

CVSS: 7.4EPSS: 0%CPEs: 12EXPL: 0CVE-2020-3260 – Cisco Aironet Series Access Points Client Packet Processing Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3260
A vulnerability in Cisco Aironet Series Access Points Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to the improper processing of client packets that are sent to an affected access point (AP). An attacker could exploit this vulnerability by sending a large number of sustained client packets to the affected AP. A successful exploit could allow the attacker to cause the affected AP to crash, resulting in a DoS condition. Una vulnerabilidad en el Software Cisco Aironet Series Access Points podría permitir a un atacante no autenticado adyacente causar una condición de denegación de servicio (DoS) sobre un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-airo-wpa-dos-5ZLs6ESz • CWE-399: Resource Management Errors CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.4EPSS: 0%CPEs: 17EXPL: 0CVE-2019-1834 – Cisco Aironet Series Access Points Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1834
A vulnerability in the internal packet processing of Cisco Aironet Series Access Points (APs) could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected AP if the switch interface where the AP is connected has port security configured. The vulnerability exists because the AP forwards some malformed wireless client packets outside of the Control and Provisioning of Wireless Access Points (CAPWAP) tunnel. An attacker could exploit this vulnerability by sending crafted wireless packets to an affected AP. A successful exploit could allow the attacker to trigger a security violation on the adjacent switch port, which could result in a DoS condition. Note: Though the Common Vulnerability Scoring System (CVSS) score corresponds to a High Security Impact Rating (SIR), this vulnerability is considered Medium because a workaround is available and exploitation requires a specific switch configuration. • http://www.securityfocus.com/bid/108000 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190417-air-ap-dos • CWE-20: Improper Input Validation •
CVSS: 4.4EPSS: 0%CPEs: 15EXPL: 0CVE-2019-1835 – Cisco Aironet Series Access Points Directory Traversal Vulnerability
https://notcve.org/view.php?id=CVE-2019-1835
A vulnerability in the CLI of Cisco Aironet Access Points (APs) could allow an authenticated, local attacker to access sensitive information stored in an AP. The vulnerability is due to improper sanitization of user-supplied input in specific CLI commands. An attacker could exploit this vulnerability by accessing the CLI of an affected AP with administrator privileges and issuing crafted commands that result in directory traversal. A successful exploit could allow the attacker to view system files on the affected device, which could contain sensitive information. Software versions 8.8 and 8.9 are affected. • http://www.securityfocus.com/bid/108001 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190417-air-ap-traversal • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
