The vulnerability exists due to a timing discrepancy when handling RSA based TLS key exchanges. A remote attacker can perform a Marvin attack and gain access to sensitive information.
3) Missing Encryption of Sensitive Data (CVE-ID: CVE-2023-45285)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to a fallback to insecure git. Using "go get" to fetch a module with the ".git" suffix may unexpectedly fallback to the insecure "git://" protocol if the module is unavailable via the secure "https://" and git+ssh://" protocols, even if GOINSECURE is not set for said module. This only affects users who are not using the module proxy and are fetching modules directly (i.e. OPROXY=off).
