Previously created connections are kept in a connection pool for reuse if they match the current setup. However, certain FTP settings such as CURLOPT_FTP_ACCOUNT, CURLOPT_FTP_ALTERNATIVE_TO_USER, CURLOPT_FTP_SSL_CCC, and CURLOPT_USE_SSL were not included in the configuration match checks, causing them to match too easily. This could lead to libcurl using the wrong credentials when performing a transfer, potentially allowing unauthorized access to sensitive information."}],"affected":[{"vendor":"n/a","product":"https://github.com/curl/curl","versions":[{"version":"Fixed in 8.0.0","status":"affected"}]}],"references":[{"url":"https://hackerone.com/reports/1892780"},{"name":"FEDORA-2023-7e7414e64d","tags":["vendor-advisory"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/36NBD5YLJXXEDZLDGNFCERWRYJQ6LAQW/"},{"url":"https://security.netapp.com/advisory/ntap-20230420-0010/"},{"name":"[debian-lts-announce] 20230421 [SECURITY] [DLA 3398-1] curl security update","tags":["mailing-list"],"url":"https://lists.debian.org/debian-lts-announce/2023/04/msg00025.html"},{"name":"GLSA-202310-12","tags":["vendor-advisory"],"url":"https://security.gentoo.org/glsa/202310-12"}],"problemTypes":[{"descriptions":[{"type":"CWE","lang":"en","description":"Authentication Bypass by Primary Weakness (CWE-305)","cweId":"CWE-305"}]}]},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T12:16:35.540Z"},"title":"CVE Program Container","references":[{"url":"https://hackerone.com/reports/1892780","tags":["x_transferred"]},{"name":"FEDORA-2023-7e7414e64d","tags":["vendor-advisory","x_transferred"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/36NBD5YLJXXEDZLDGNFCERWRYJQ6LAQW/"},{"url":"https://security.netapp.com/advisory/ntap-20230420-0010/","tags":["x_transferred"]},{"name":"[debian-lts-announce] 20230421 [SECURITY] [DLA 3398-1] curl security update","tags":["mailing-list","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2023/04/msg00025.html"},{"name":"GLSA-202310-12","tags":["vendor-advisory","x_transferred"],"url":"https://security.gentoo.org/glsa/202310-12"}]},{"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":5.9,"attackVector":"NETWORK","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","integrityImpact":"NONE","userInteraction":"NONE","attackComplexity":"HIGH","availabilityImpact":"NONE","privilegesRequired":"NONE","confidentialityImpact":"HIGH"}},{"other":{"type":"ssvc","content":{"timestamp":"2025-06-03T18:24:11.710118Z","id":"CVE-2023-27535","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"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":"2025-06-09T14:47:57.951Z"}}]}}
