On Windows, path.Base acts differently to filepath.Base, since Windows uses a different path separator (\\ vs. /), allowing a user to provide a relative path, i.e. .well-known/acme-challenge/..\\..\\asd becomes ..\\..\\asd. The extracted path is then suffixed with +http-01, joined with the cache directory, and opened. Since the controlled path is suffixed with +http-01 before opening, the impact of this is significantly limited, since it only allows reading arbitrary files on the system if and only if they have this suffix."}],"affected":[{"vendor":"golang.org/x/crypto","product":"golang.org/x/crypto/acme/autocert","collectionURL":"https://pkg.go.dev","packageName":"golang.org/x/crypto/acme/autocert","versions":[{"version":"0","lessThan":"0.0.0-20220525230936-793ad666bf5e","status":"affected","versionType":"semver"}],"platforms":["windows"],"programRoutines":[{"name":"DirCache.Get"},{"name":"DirCache.Put"},{"name":"DirCache.Delete"},{"name":"HostWhitelist"},{"name":"Manager.GetCertificate"},{"name":"Manager.Listener"},{"name":"NewListener"},{"name":"listener.Accept"},{"name":"listener.Close"}],"defaultStatus":"unaffected"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE 22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')"}]}],"references":[{"url":"https://go.dev/cl/408694"},{"url":"https://go.dev/issue/53082"},{"url":"https://pkg.go.dev/vuln/GO-2024-2961"}],"credits":[{"lang":"en","value":"Juho Nurminen of Mattermost"}]},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-03T06:56:13.171Z"},"title":"CVE Program Container","references":[{"url":"https://go.dev/cl/408694","tags":["x_transferred"]},{"url":"https://go.dev/issue/53082","tags":["x_transferred"]},{"url":"https://pkg.go.dev/vuln/GO-2024-2961","tags":["x_transferred"]}]},{"affected":[{"vendor":"golang","product":"crypto","cpes":["cpe:2.3:a:golang:crypto:-:*:*:*:*:*:*:*"],"defaultStatus":"unknown","versions":[{"version":"0","status":"affected","lessThan":"0.0.0-20220525230936-793ad666bf5e","versionType":"custom"}]}],"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":7.5,"attackVector":"NETWORK","baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","integrityImpact":"NONE","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"NONE","privilegesRequired":"NONE","confidentialityImpact":"HIGH"}},{"other":{"type":"ssvc","content":{"timestamp":"2024-07-03T13:57:10.933970Z","id":"CVE-2022-30636","options":[{"Exploitation":"poc"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-08-07T16:21:06.868Z"}}]}}
