It affects 645 different API actions across 40 different AWS services. This would be beneficial for a Penetration Tester or a Red Teamer to enumerate what permissions the role or user they’ve compromised has access to without alerting the blue team as no logs are generated in CloudTrail. --------------------------------------------- https://frichetten.com/blog/aws-api-enum-vuln/ ∗∗∗ Secret fragments: Remote code execution on Symfony based websites ∗∗∗ --------------------------------------------- This configuration value, secret, is also used, for instance, to build CSRF tokens and remember-me tokens. Given its importance, this value must obviously be very random. Unfortunately, we discovered that oftentimes, the secret either has a default value, or there exist ways to obtain the value, bruteforce it offline, or to purely and simply bypass the security check that it is involved with.
