Summary
An issue was discovered in Progress DataDirect Connect for ODBC before version 08.02.2770 for Oracle. When using Oracle Advanced Security (OAS) encryption, if an error occurs while initializing the encryption object, the code falls back to a different encryption mechanism that uses an insecure random number generator to generate the private key.
Risk Assessment
An attacker can predict the output of this random number generator, potentially leading to the decryption of traffic between the driver and the database server. The vulnerability does not exist if SSL/TLS encryption is used.
Recommendation
It is recommended to upgrade to version 08.02.2770 or later and to use SSL/TLS encryption to secure communication.
Original NVD description (English source)
An issue was discovered in Progress DataDirect Connect for ODBC before 08.02.2770 for Oracle. When using Oracle Advanced Security (OAS) encryption, if an error is encountered initializing the encryption object used to encrypt data, the code falls back to a different encryption mechanism that uses an insecure random number generator to generate the private key. It is possible for a well-placed attacker to predict the output of this random number generator, which could lead to an attacker decrypting traffic between the driver and the database server. The vulnerability does not exist if SSL / TLS encryption is used.
