Initial Sequence Numbers (ISNs) for TCP connections are derived from an insufficiently random source. As a result, the ISN of current and future TCP connections could be predictable. An attacker could hijack existing sessions or spoof future ones.", "severity": [ { "type": "CVSS_V3", "score": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N" } ], "affected": [], "references": [ { "type": "ADVISORY", "url": "https://nvd.nist.gov/vuln/detail/CVE-2020-28388" }, { "type": "WEB", "url": "https://cert-portal.siemens.com/productcert/pdf/ssa-180579.pdf" }, { "type": "WEB", "url": "https://cert-portal.siemens.com/productcert/pdf/ssa-344238.pdf" }, { "type": "WEB", "url": "https://cert-portal.siemens.com/productcert/pdf/ssa-362164.pdf" }, { "type": "WEB", "url": "https://cert-portal.siemens.com/productcert/pdf/ssa-436469.pdf" } ], "database_specific": { "cwe_ids": [ "CWE-342" ], "severity": "MODERATE", "github_reviewed": false, "github_reviewed_at": null, "nvd_published_at": "2021-02-09T18:15:00Z" } }
