Descriptions

A flaw was found in dogtag-pki and pki-core. The token authentication scheme can be bypassed with a LDAP injection. By passing the query string parameter sessionID=*, an attacker can authenticate with an existing session saved in the LDAP directory server, which may lead to escalation of privilege.

Se encontró una falla en dogtag-pki y pki-core. El esquema de autenticación de token se puede omitir con una inyección LDAP. Al pasar el parámetro de cadena de consulta sessionID=*, un atacante puede autenticarse con una sesión existente guardada en el servidor de directorio LDAP, lo que puede conducir a una escalada de privilegios.

An update for pki-core is now available for Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support, Red Hat Enterprise Linux 8.6 Update Services for SAP Solutions, and Red Hat Enterprise Linux 8.6 Telecommunications Update Service. Issues addressed include a bypass vulnerability.

*Credits: Red Hat would like to thank Pham Van Khanh (Calif) for reporting this issue.
