CVE-2023-27535
Full vulnerability record from the local CVENow database.
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.

"value": "Existe una vulnerabilidad de omisión de autenticación en libcurl anterior a 8.0.0 en la función de reutilización de conexiones FTP que puede resultar en el uso de credenciales incorrectas durante transferencias posteriores. Las conexiones creadas previamente se mantienen en un grupo de conexiones para su reutilización si coinciden con la configuración actual. Sin embargo, ciertas configuraciones FTP como CURLOPT_FTP_ACCOUNT, CURLOPT_FTP_ALTERNATIVE_TO_USER, CURLOPT_FTP_SSL_CCC y CURLOPT_USE_SSL no se incluyeron en las comprobaciones de coincidencia de configuración, lo que provocó que coincidieran con demasiada facilidad. Esto podría llevar a libcurl a usar las credenciales incorrectas al realizar una transferencia, lo que podría permitir el acceso no autorizado a información sensible."
