CVE-2023-45287 is a vulnerability that affects the Go programming language before version 1.20. It is related to the RSA-based TLS key exchanges and the math/big library, which is not constant time. The vulnerability allows for potential timing attacks, where the removal of PKCS#1 padding may leak timing information and potentially expose session key bits. To remediate this vulnerability, organizations should update to Go version 1.20 or later, as it switched to a fully constant time RSA implementation. This vulnerability poses a high danger to organizations as it can result in the exposure of confidential information through timing attacks.
