application layer protocol content confusion attack, exploiting TLS servers implementing different protocols but using compatible certificates, such as multi-domain or wildcard certificates. A MiTM attacker having access to victim's traffic at the TCP/IP layer can redirect traffic from one subdomain to another, resulting in a valid TLS session. This breaks the authentication of TLS and cross-protocol attacks may be possible where the behavior of one protocol service may compromise the other at the application layer.","title":"CVE description"}],"product_status":{"recommended":["SUSE Linux Enterprise Module for Server Applications 15 SP4:vsftpd-3.0.5-150400.3.3.1.aarch64","SUSE Linux Enterprise Module for Server Applications 15 SP4:vsftpd-3.0.5-150400.3.3.1.ppc64le","SUSE Linux Enterprise Module for Server Applications 15 SP4:vsftpd-3.0.5-150400.3.3.1.s390x","SUSE Linux Enterprise Module for Server Applications 15 SP4:vsftpd-3.0.5-150400.3.3.1.x86_64","openSUSE Leap 15.4:vsftpd-3.0.5-150400.3.3.1.aarch64","openSUSE Leap 15.4:vsftpd-3.0.5-150400.3.3.1.ppc64le","openSUSE Leap 15.4:vsftpd-3.0.5-150400.3.3.1.s390x","openSUSE Leap 15.4:vsftpd-3.0.5-150400.3.3.1.x86_64"]},"references":[{"category":"external","summary":"CVE-2021-3618","url":"https://www.suse.com/security/cve/CVE-2021-3618"},{"category":"external","summary":"SUSE Bug 1187678 for CVE-2021-3618","url":"https://bugzilla.suse.com/1187678"}],"remediations":[{"category":"vendor_fix","details":"To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or \"zypper patch\".\n","product_ids":["SUSE Linux Enterprise Module for Server Applications 15 SP4:vsftpd-3.0.5-150400.3.3.1.aarch64","SUSE Linux Enterprise Module for Server Applications 15 SP4:vsftpd-3.0.5-150400.3.3.1.ppc64le","SUSE Linux Enterprise Module for Server Applications 15 SP4:vsftpd-3.0.5-150400.3.3.1.s390x","SUSE Linux Enterprise Module for Server Applications 15 SP4:vsftpd-3.0.5-150400.3.3.1.x86_64","openSUSE Leap 15.4:vsftpd-3.0.5-150400.3.3.1.aarch64","openSUSE Leap 15.4:vsftpd-3.0.5-150400.3.3.1.ppc64le","openSUSE Leap 15.4:vsftpd-3.0.5-150400.3.3.1.s390x","openSUSE Leap 15.4:vsftpd-3.0.5-150400.3.3.1.x86_64"]}],"scores":[{"cvss_v3":{"baseScore":7.4,"baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"products":["SUSE Linux Enterprise Module for Server Applications 15 SP4:vsftpd-3.0.5-150400.3.3.1.aarch64","SUSE Linux Enterprise Module for Server Applications 15 SP4:vsftpd-3.0.5-150400.3.3.1.ppc64le","SUSE Linux Enterprise Module for Server Applications 15 SP4:vsftpd-3.0.5-150400.3.3.1.s390x","SUSE Linux Enterprise Module for Server Applications 15 SP4:vsftpd-3.0.5-150400.3.3.1.x86_64","openSUSE Leap 15.4:vsftpd-3.0.5-150400.3.3.1.aarch64","openSUSE Leap 15.4:vsftpd-3.0.5-150400.3.3.1.ppc64le","openSUSE Leap 15.4:vsftpd-3.0.5-150400.3.3.1.s390x","openSUSE Leap 15.4:vsftpd-3.0.5-150400.3.3.1.x86_64"]}],"threats":[{"category":"impact","date":"2022-09-20T12:47:13Z","details":"important"}],"title":"CVE-2021-3618"}]}
