CVE-2020-8911

CVE-2020-8911 describes a padding oracle in the AWS S3 Crypto SDK for Go (older GoLang S3 encryption client). The vulnerability arises because AES-CBC encryption was used without a MAC, enabling an attacker with write access to the target S3 bucket to observe decryption outcomes and reconstruct p...

CVE-2020-8912 In-band key negotiation issue in AWS S3 Crypto SDK for GoLang

A vulnerability in the in-band key negotiation exists in the AWS S3 Crypto SDK for GoLang versions prior to V2. An attacker with write access to the targeted bucket can change the encryption algorithm of an object in the bucket, which can then allow them to change AES-GCM to AES-CTR. Using this i...

CVE-2020-8911 CBC padding oracle in AWS S3 Crypto SDK for GoLang

A padding oracle vulnerability exists in the AWS S3 Crypto SDK for GoLang versions prior to V2. The SDK allows users to encrypt files with AES-CBC without computing a Message Authentication Code MAC, which then allows an attacker who has write access to the target's S3 bucket and can observe...
