Vulnerability from variot

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. Cisco Firepower Threat Defense is a suite of unified software that provides next-generation firewall services. Cisco Web Security Appliance is a web security appliance. The appliance provides SaaS-based access control, real-time network reporting and tracking, and security policy formulation.

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": "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. Cisco Firepower Threat Defense is a suite of unified software that provides next-generation firewall services. Cisco Web Security Appliance is a web security appliance. The appliance provides SaaS-based access control, real-time network reporting and tracking, and security policy formulation. \n\nFor the stable distribution (bullseye), these problems have been fixed in\nversion 2.9.20-0+deb11u1. \n\nWe recommend that you upgrade your snort packages. \n\nFor the detailed security status of snort please refer to\nits security tracker page at:\nhttps://security-tracker.debian.org/tracker/snort\n\nFurther information about Debian Security Advisories, how to apply\nthese updates to your system and frequently asked questions can be\nfound at: https://www.debian.org/security/\n\nMailing list: debian-security-announce@lists.debian.org\n-----BEGIN PGP SIGNATURE-----\n\niQKTBAEBCgB9FiEErPPQiO8y7e9qGoNf2a0UuVE7UeQFAmPw/Y5fFIAAAAAALgAo\naXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldEFD\nRjNEMDg4RUYzMkVERUY2QTFBODM1RkQ5QUQxNEI5NTEzQjUxRTQACgkQ2a0UuVE7\nUeQRrA/9EQ9kF1LT2fYUGFMyKeCQQFTB8tfIsyz2VUrGUtWlVDKsDVqfEMWa6Zwx\nrAaFnAPOBi1KNX1laencuphuiDIxLmvA0ShpHKo/R3vY4WXmNwJMjPWNr82oTw8j\nCEggyfj9i5V1EwZZi0B3L4WP1pCQcJRN6XVB3FJWZScyQFtRH0xO7l9acIV68lTs\n9hGDDe2wn5ufHh0sXskZitgYoXfdHjjl3CzFxrmGGDq9KFr8rDIEUnZrm58DCRNL\nRkDmvxrEEsXGmzQlhT/2ea88aIXgNM4xnDztr3iV1v8JOMb6BwehrH43NgdDb5V8\n6xBcHuXOLNI75mca1TQxwUd8PSNo3YK60IbDC2ztcUIIvl1xk8bDFyABb3gKvGoR\nizKFYej4hNeZb+0HWHsnO9vvP4t6LkKF/iIGNNVNmA9ZJA94ESCfItSozIITqRE2\nsJQ43X9uQhX2p/dfeyNoOJDhie0RyZyg0rPxIDNonP1YJ8kTjMMHnRNqGn9MkVYK\nbNr1/sdLhH0TXvs5XoL9b9YjUPL67hDHL9bHLByOKNSxXrth+TcqFX+eg7Bztn1A\nvS4Sc2TWCuBa3jdrS9WJiy58aB1sTABRhN+tY4wVs+A9vIr1dKHn4wsB8axmpYDW\ncyzVbz9Q+fC+gXwDusZccBqfD7rByEFWXflBFI4PDXRrW+NPy8w\\xdb5k\n-----END PGP SIGNATURE-----\n",
