The product allows users to configure authorization checks as shell commands through the tac_plus.cfg configuration file. These are executed when a client sends an authorization request with a username that has pre-authorization directives configured. However, it is possible to inject additional commands into these checks because strings from TACACS+ packets are used as command-line arguments. If the installation lacks a a pre-shared secret (there is no pre-shared secret by default), then the injection can be triggered without authentication. (The attacker needs to know a username configured to use a pre-authorization command.) NOTE: this is related to CVE-2023-45239 but the issue is in the original Shrubbery product, not Meta's fork."}],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":[{"url":"https://github.com/takeshixx/tac_plus-pre-auth-rce"}],"problemTypes":[{"descriptions":[{"type":"text","lang":"en","description":"n/a"}]}]},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T21:37:54.509Z"},"title":"CVE Program Container","references":[{"url":"https://github.com/takeshixx/tac_plus-pre-auth-rce","tags":["x_transferred"]}]},{"problemTypes":[{"descriptions":[{"type":"CWE","cweId":"CWE-94","lang":"en","description":"CWE-94 Improper Control of Generation of Code ('Code Injection')"}]}],"affected":[{"vendor":"shrubbery","product":"tac_plus_2x","cpes":["cpe:2.3:a:shrubbery:tac_plus_2x:*:*:*:*:*:*:*:*"],"defaultStatus":"unknown","versions":[{"version":"0","status":"affected","lessThanOrEqual":"f_4.0.4.28","versionType":"custom"}]},{"vendor":"shrubbery","product":"tac_plus_3x","cpes":["cpe:2.3:a:shrubbery:tac_plus_3x:*:*:*:*:*:*:*:*"],"defaultStatus":"unknown","versions":[{"version":"0","status":"affected","lessThanOrEqual":"f_4.0.4.28","versionType":"custom"}]},{"vendor":"shrubbery","product":"tac_plus_4x","cpes":["cpe:2.3:a:shrubbery:tac_plus_4x:*:*:*:*:*:*:*:*"],"defaultStatus":"unknown","versions":[{"version":"0","status":"affected","lessThanOrEqual":"f_4.0.4.28","versionType":"custom"}]}],"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":9.8,"attackVector":"NETWORK","baseSeverity":"CRITICAL","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","integrityImpact":"HIGH","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"HIGH","privilegesRequired":"NONE","confidentialityImpact":"HIGH"}},{"other":{"type":"ssvc","content":{"timestamp":"2024-08-20T15:59:52.293639Z","id":"CVE-2023-48643","options":[{"Exploitation":"poc"},{"Automatable":"yes"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-08-20T16:07:45.689Z"}}]},"dataVersion":"5.1"}
