CVSS: 6.6EPSS: 0%CPEs: 16EXPL: 0CVE-2021-34761 – Cisco Firepower Threat Defense Software CLI Arbitrary File Write Vulnerability
https://notcve.org/view.php?id=CVE-2021-34761
A vulnerability in Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to overwrite or append arbitrary data to system files using root-level privileges. The attacker must have administrative credentials on the device. This vulnerability is due to incomplete validation of user input for a specific CLI command. An attacker could exploit this vulnerability by authenticating to the device with administrative privileges and issuing a CLI command with crafted user parameters. A successful exploit could allow the attacker to overwrite or append arbitrary data to system files using root-level privileges. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-file-write-SHVcmQVc • CWE-73: External Control of File Name or Path CWE-668: Exposure of Resource to Wrong Sphere •

CVSS: 8.6EPSS: 0%CPEs: 6EXPL: 0CVE-2021-34749 – Multiple Cisco Products Server Name Identification Data Exfiltration Vulnerability
https://notcve.org/view.php?id=CVE-2021-34749
A vulnerability in Server Name Identification (SNI) request filtering of Cisco Web Security Appliance (WSA), Cisco Firepower Threat Defense (FTD), and the Snort detection engine could allow an unauthenticated, remote attacker to bypass filtering technology on an affected device and exfiltrate data from a compromised host. This vulnerability is due to inadequate filtering of the SSL handshake. An attacker could exploit this vulnerability by using data from the SSL client hello packet to communicate with an external server. A successful exploit could allow the attacker to execute a command-and-control attack on a compromised host and perform additional data exfiltration attacks. Una vulnerabilidad en el filtrado de peticiones Server Name Identification (SNI) de Cisco Web Security Appliance (WSA), Cisco Firepower Threat Defense (FTD) y Snort detection engine podría permitir a un atacante no autenticado remoto omitir la tecnología de filtrado en un dispositivo afectado y exfiltrar datos de un host comprometido. • https://lists.debian.org/debian-lts-announce/2023/02/msg00011.html https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sni-data-exfil-mFgzXqLN https://www.debian.org/security/2023/dsa-5354 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
