CVE-2023-20246 2 Cisco, Snort 2 Unified Threat Defense, Snort 2023-11-09 N/A 5.3 MEDIUM
Multiple Cisco products are affected by a vulnerability in Snort access control policies that could allow an unauthenticated, remote attacker to bypass the configured policies on an affected system. This vulnerability is due to a logic error that occurs when the access control policies are being populated. An attacker could exploit this vulnerability by establishing a connection to an affected device. A successful exploit could allow the attacker to bypass configured access control rules on the affected system.
CVE-2023-20071 2 Cisco, Snort 5 Cyber Vision, Firepower Threat Defense, Meraki Mx Security Appliance Firmware and 2 more 2023-11-09 N/A 5.8 MEDIUM
Multiple Cisco products are affected by a vulnerability in the Snort detection engine that could allow an unauthenticated, remote attacker to bypass the configured policies on an affected system. This vulnerability is due to a flaw in the FTP module of the Snort detection engine. An attacker could exploit this vulnerability by sending crafted FTP traffic through an affected device. A successful exploit could allow the attacker to bypass FTP inspection and deliver a malicious payload.
CVE-2021-1495 2 Cisco, Snort 22 C8200-1n-4t, C8200l-1n-4t, Catalyst 8300-1n1s-4t2x and 19 more 2021-05-09 5.0 MEDIUM 5.3 MEDIUM
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.
CVE-2021-1236 2 Cisco, Snort 19 Csr 1000v, Firepower Management Center, Firepower Threat Defense and 16 more 2021-01-19 5.0 MEDIUM 5.3 MEDIUM
Multiple Cisco products are affected by a vulnerability in the Snort application detection engine that could allow an unauthenticated, remote attacker to bypass the configured policies on an affected system. The vulnerability is due to a flaw in the detection algorithm. An attacker could exploit this vulnerability by sending crafted packets that would flow through an affected system. A successful exploit could allow the attacker to bypass the configured policies and deliver a malicious payload to the protected network.
CVE-2021-1224 2 Cisco, Snort 43 Csr 1000v, Firepower Management Center, Firepower Threat Defense and 40 more 2021-01-19 5.0 MEDIUM 5.3 MEDIUM
Multiple Cisco products are affected by a vulnerability with TCP Fast Open (TFO) when used in conjunction with 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 detection of the HTTP payload if it is contained at least partially within the TFO connection handshake. An attacker could exploit this vulnerability by sending crafted TFO packets with an HTTP payload through an affected device. A successful exploit could allow the attacker to bypass configured file policy for HTTP packets and deliver a malicious payload.
CVE-2020-3299 2 Cisco, Snort 16 1100-4p, 1100-8p, 1101-4p and 13 more 2020-10-27 5.0 MEDIUM 5.8 MEDIUM
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 detection of modified HTTP packets used in chunked responses. 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.
