Описание
A flaw in the libcurl SASL negotiation for LDAP authentication allows an
incomplete handshake sequence to be misinterpreted as a successful
cryptographic verification. An attacker executing a Man-in-the-Middle (MITM)
attack can inject a premature or shortcut response that bypasses complete peer
validation.
A flaw was found in libcurl's SASL (Simple Authentication and Security Layer) negotiation for LDAP (Lightweight Directory Access Protocol) authentication when using the OpenLDAP backend. An incomplete handshake sequence can be misinterpreted as a successful cryptographic verification. A remote attacker, by performing a Man-in-the-Middle (MITM) attack, could inject a premature response to bypass complete peer validation, leading to an authentication bypass.
Отчет
This Low impact flaw in libcurl's SASL negotiation for LDAP authentication could allow an attacker to bypass peer validation through a Man-in-the-Middle (MITM) attack. Exploitation requires an active network attacker to inject a premature response during the authentication handshake.
Меры по смягчению последствий
To mitigate enforce strict mutual authentication and cryptographic verification of both endpoints before transmitting sensitive data. Implement robust TLS/SSL configurations with explicit certificate pinning or strict CA validation to prevent Man-in-the-Middle (MITM) attackers from intercepting, prematurely concluding, or manipulating the handshake.
