This weakness allows the attacker to manipulate the various iterations of the telnetd startup state machine and eventually obtain a root shell on the device, by means of an exchange of crafted UDP packets. In all versions but K2 22.5.9.163 and K3C 32.1.15.93 a successful attack also requires the exploitation of a null-byte interaction error (CVE-2022-25219).", "severity": [ { "type": "CVSS_V3", "score": "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H" } ], "affected": [], "references": [ { "type": "ADVISORY", "url": "https://nvd.nist.gov/vuln/detail/CVE-2022-25218" }, { "type": "WEB", "url": "https://www.tenable.com/security/research/tra-2022-01" } ], "database_specific": { "cwe_ids": [], "severity": "HIGH", "github_reviewed": false, "github_reviewed_at": null, "nvd_published_at": "2022-03-10T17:47:00Z" } }
