{"id":"BIT-kyverno-2023-54356","summary":"Kyverno before 1.9.5 Sweet32 Medium Strength Cipher Suites","details":"Kyverno versions 1.9.4 and earlier support insecure 3DES cipher suites (TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA and TLS_RSA_WITH_3DES_EDE_CBC_SHA) on their TLS endpoints. These 64-bit block ciphers are vulnerable to the Sweet32 attack (CVE-2016-2183), which, over very long-lived TLS connections carrying large volumes of traffic, could allow an attacker to recover small amounts of plaintext. The issue is fixed in Kyverno 1.9.5 and 1.10.0.","aliases":["CVE-2023-54356","GHSA-hgv6-w7r3-w4qw","GO-2023-1804"],"modified":"2026-10-14T11:10:48.978536185Z","published":"2026-10-14T08:47:25.519Z","database_specific":{"severity":"Critical","cpes":["cpe:2.3:a:kyverno:kyverno:*:*:*:*:*:go:*:*"]},"references":[{"type":"WEB","url":"https://github.com/kyverno/kyverno/security/advisories/GHSA-hgv6-w7r3-w4qw"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-54356"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/kyverno-before-1.9.5-sweet32-medium-strength-cipher-suites"}],"affected":[{"package":{"name":"kyverno","ecosystem":"Bitnami","purl":"pkg:bitnami/kyverno"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.9.5"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/kyverno/BIT-kyverno-2023-54356.json"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}],"schema_version":"1.9.0"}
