CVSS: 5.3EPSS: 0%CPEs: 33EXPL: 0CVE-2021-34787 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software Identity-Based Rule Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2021-34787
A vulnerability in the identity-based firewall (IDFW) rule processing feature of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to bypass security protections. This vulnerability is due to improper handling of network requests by affected devices configured to use object group search. An attacker could exploit this vulnerability by sending a specially crafted network request to an affected device. A successful exploit could allow the attacker to bypass access control list (ACL) rules on the device, bypass security protections, and send network traffic to unauthorized hosts. Una vulnerabilidad en la funcionalidad de procesamiento de reglas del firewall basado en la identidad (IDFW) del software Cisco Adaptive Security Appliance (ASA) y del software Cisco Firepower Threat Defense (FTD) podría permitir a un atacante remoto no autenticado omitir las protecciones de seguridad. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asaftd-rule-bypass-ejjOgQEY • CWE-183: Permissive List of Allowed Inputs CWE-755: Improper Handling of Exceptional Conditions •

CVSS: 8.1EPSS: 0%CPEs: 22EXPL: 0CVE-2021-34762 – Cisco Firepower Management Center Software Authenticated Directory Traversal Vulnerability
https://notcve.org/view.php?id=CVE-2021-34762
A vulnerability in the web-based management interface of Cisco Firepower Management Center (FMC) Software could allow an authenticated, remote attacker to perform a directory traversal attack on an affected device. The attacker would require valid device credentials. The vulnerability is due to insufficient input validation of the HTTPS URL by the web-based management interface. An attacker could exploit this vulnerability by sending a crafted HTTPS request that contains directory traversal character sequences to an affected device. A successful exploit could allow the attacker to read or write arbitrary files on the device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-fmc-dir-traversal-95UyW5tk • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-26: Path Traversal: '/dir/../filename' •
