Vulnerability from variot
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. plural Cisco The product contains a privilege management vulnerability.Information may be tampered with. Cisco 3000 Series Industrial Security Appliances, etc. are all products of Cisco (Cisco). Cisco 3000 Series Industrial Security Appliances are 3000 Series Industrial Security Appliances. Cisco 4000 Series Integrated Services Routers (ISRS) are 4000 Series enterprise-class multiservice routers. Cisco Cloud Services Router 1000V Series is a 1000v series cloud service routing software. A security vulnerability exists in several Cisco products. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512
Debian Security Advisory DSA-5354-1 security@debian.org https://www.debian.org/security/ Markus Koschany February 18, 2023 https://www.debian.org/security/faq
Package : snort CVE ID : CVE-2020-3299 CVE-2020-3315 CVE-2021-1223 CVE-2021-1224 CVE-2021-1236 CVE-2021-1494 CVE-2021-1495 CVE-2021-34749 CVE-2021-40114 Debian Bug : 1021276
Multiple security vulnerabilities were discovered in snort, a flexible Network Intrusion Detection System, which could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition or bypass filtering technology on an affected device and ex-filtrate data from a compromised host.
For the stable distribution (bullseye), these problems have been fixed in version 2.9.20-0+deb11u1.
We recommend that you upgrade your snort packages.
For the detailed security status of snort please refer to its security tracker page at: https://security-tracker.debian.org/tracker/snort

"data": "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. plural Cisco The product contains a privilege management vulnerability.Information may be tampered with. Cisco 3000 Series Industrial Security Appliances, etc. are all products of Cisco (Cisco). Cisco 3000 Series Industrial Security Appliances are 3000 Series Industrial Security Appliances. Cisco 4000 Series Integrated Services Routers (ISRS) are 4000 Series enterprise-class multiservice routers. Cisco Cloud Services Router 1000V Series is a 1000v series cloud service routing software.
