CVSS: 5.8EPSS: 0%CPEs: 26EXPL: 0CVE-2021-1495 – Multiple Cisco Products Snort HTTP Detection Engine File Policy Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2021-1495
Multiple Cisco products are affected by a vulnerability in the Snort detection engine that could allow an unauthenticated, remote attacker to bypass a configured file policy for HTTP. The vulnerability is due to incorrect handling of specific HTTP header parameters. An attacker could exploit this vulnerability by sending crafted HTTP packets through an affected device. A successful exploit could allow the attacker to bypass a configured file policy for HTTP packets and deliver a malicious payload. Múltiples productos de Cisco están afectados por una vulnerabilidad en el motor de detección Snort que podría permitir a un atacante remoto no autenticado omitir una política de archivos configurada para HTTP. • https://lists.debian.org/debian-lts-announce/2023/02/msg00011.html https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-http-fp-bp-KfDdcQhc https://www.debian.org/security/2023/dsa-5354 • CWE-755: Improper Handling of Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2021-1493
A vulnerability in the web services interface of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, remote attacker to cause a buffer overflow on an affected system. The vulnerability is due to insufficient boundary checks for specific data that is provided to the web services interface of an affected system. An attacker could exploit this vulnerability by sending a malicious HTTP request. A successful exploit could allow the attacker to cause a buffer overflow condition on the affected system, which could disclose data fragments or cause the device to reload, resulting in a denial of service (DoS) condition. Una vulnerabilidad en la interfaz de servicios web del software Cisco Adaptive Security Appliance (ASA) y el software Cisco Firepower Threat Defense (FTD), podría permitir a un atacante remoto autenticado causar un desbordamiento del búfer en un sistema afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-memc-dos-fncTyYKG • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

https://notcve.org/view.php?id=CVE-2021-1476
A vulnerability in the CLI of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system (OS) of an affected device. The vulnerability is due to insufficient input validation of commands that are supplied by the user. An attacker could exploit this vulnerability by authenticating to a device and submitting crafted input for specific commands. A successful exploit could allow the attacker to execute commands on the underlying OS with root privileges. To exploit this vulnerability, an attacker must have valid administrator-level credentials. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asa-ftd-cmd-inj-SELprvG • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
