{"id":"AZL-25805","summary":"CVE-2023-27535 affecting package mysql for versions less than 8.0.34-1","details":"An authentication bypass vulnerability exists in libcurl \u003c8.0.0 in the FTP connection reuse feature that can result in wrong credentials being used during subsequent transfers. 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.","modified":"2026-04-01T05:08:03.145654Z","published":"2023-03-30T20:15:07Z","upstream":["CVE-2023-27535"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-27535"}],"affected":[{"package":{"name":"mysql","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/mysql"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.0.34-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-25805.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
