This allows a site to set cookies that then would get sent to\ndifferent and unrelated sites and domains.\n\nIt could do this by exploiting a mixed case flaw in curl's function that\nverifies a given cookie domain against the Public Suffix List (PSL). For\nexample a cookie could be set with `domain=co.UK` when the URL used a lower\ncase hostname `curl.co.uk`, even though `co.uk` is listed as a PSL domain."},{"lang":"es","value":"Esta falla permite que un servidor HTTP malicioso establezca \"supercookies\" en curl que luego se devuelven a más orígenes de los que están permitidos o son posibles. Esto permite que un sitio establezca cookies que luego se enviarán a sitios y dominios diferentes y no relacionados. Podría hacer esto explotando una falla de mayúsculas y minúsculas en la función de curl que verifica un dominio de cookie determinado con Public Suffix List (PSL). Por ejemplo, una cookie podría configurarse con `domain=co.UK` cuando la URL utilizaba un nombre de host en minúscula `curl.co.uk`, aunque `co.uk` aparezca como un dominio PSL."}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":2.5},{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":2.5}]},"weaknesses":[{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"NVD-CWE-noinfo"}]},{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","description":[{"lang":"en","value":"CWE-178"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:haxx:curl:*:*:*:*:*:*:*:*","versionStartIncluding":"7.46.0","versionEndIncluding":"8.4.0","matchCriteriaId":"CDCA27BA-B527-4B8F-91D5-CEE58282FD45"}]}]},{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:fedoraproject:fedora:39:*:*:*:*:*:*:*","matchCriteriaId":"B8EDB836-4E6A-4B71-B9B2-AA3E03E0F646"}]}]}],"references":[{"url":"https://curl.se/docs/CVE-2023-46218.html","source":"support@hackerone.com","tags":["Patch","Vendor Advisory"]},{"url":"https://hackerone.com/reports/2212193","source":"support@hackerone.com","tags":["Exploit","Issue Tracking","Patch","Third Party Advisory"]},{"url":"https://lists.debian.org/debian-lts-announce/2023/12/msg00015.html","source":"support@hackerone.com"},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/3ZX3VW67N4ACRAPMV2QS2LVYGD7H2MVE/","source":"support@hackerone.com","tags":["Mailing List","Third Party Advisory"]},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/UOGXU25FMMT2X6UUITQ7EZZYMJ42YWWD/","source":"support@hackerone.com"},{"url":"https://security.netapp.com/advisory/ntap-20240125-0007/","source":"support@hackerone.com"},{"url":"https://www.debian.org/security/2023/dsa-5587","source":"support@hackerone.com"},{"url":"https://curl.se/docs/CVE-2023-46218.html","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch","Vendor Advisory"]},{"url":"https://hackerone.com/reports/2212193","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Exploit","Issue Tracking","Patch","Third Party Advisory"]},{"url":"https://lists.debian.org/debian-lts-announce/2023/12/msg00015.html","source":"af854a3a-2127-422b-91ae-364da2661108"},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/3ZX3VW67N4ACRAPMV2QS2LVYGD7H2MVE/","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Mailing List","Third Party Advisory"]},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/UOGXU25FMMT2X6UUITQ7EZZYMJ42YWWD/","source":"af854a3a-2127-422b-91ae-364da2661108"},{"url":"https://security.netapp.com/advisory/ntap-20240125-0007/","source":"af854a3a-2127-422b-91ae-364da2661108"},{"url":"https://www.debian.org/security/2023/dsa-5587","source":"af854a3a-2127-422b-91ae-364da2661108"}]}}]}
