发布于3月6日3月6日 Members Ubuntu: (Multiple Advisories) (CVE-2023-27535): curl vulnerabilities Severity 7 CVSS (AV:N/AC:M/Au:N/C:C/I:N/A:N) Published 03/20/2023 Created 03/29/2023 Added 03/22/2023 Modified 01/28/2025 Description An authentication bypass vulnerability exists in libcurl <8.0.0 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.
