Описание
A vulnerability exists where a connection requiring TLS incorrectly reuses an
existing unencrypted connection from the same connection pool. If an initial
transfer is made in clear-text (via IMAP, SMTP, or POP3), a subsequent request
to that same host bypasses the TLS requirement and instead transmit data
unencrypted.
A flaw was found in curl. A remote attacker could exploit this by initiating an unencrypted connection (via IMAP, SMTP, or POP3) and then making a subsequent request to the same host that requires Transport Layer Security (TLS). Due to incorrect connection reuse, the subsequent request would bypass the TLS requirement, leading to the transmission of sensitive information in cleartext. This vulnerability, categorized as Cleartext Transmission of Sensitive Information (CWE-319), results in information disclosure.
Отчет
Moderate: This flaw in curl allows for information disclosure when an unencrypted connection is incorrectly reused for a subsequent request that expects TLS. This can lead to the cleartext transmission of sensitive data, potentially affecting Red Hat products that utilize curl for IMAP, SMTP, or POP3 connections where connection reuse is enabled.
Меры по смягчению последствий
To mitigate this issue, avoid using clear-text IMAP, POP3, or SMTP transfers with curl. Ensure that all connections for these protocols are initiated with TLS from the outset to prevent the reuse of unencrypted connections.
