What is CVE-2023-34363?
CVE-2023-34363 is a medium-severity vulnerability in n/a, published on 9 Jun 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
Weakness: CWE-338
