AWS S3 Crypto SDK metadata weak hash

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in AWS S3 Crypto SDK (affected version not known). It has been declared as problematic. Affected by this vulnerability is some unknown functionality. The manipulation of the argument metadata with an unknown input leads to a weak hash vulnerability. The CWE definition for the vulnerability is CWE-328. The product uses an algorithm that produces a digest (output value) that does not meet security expectations for a hash function that allows an adversary to reasonably determine the original input (preimage attack), find another input that can produce the same hash (2nd preimage attack), or find multiple inputs that evaluate to the same hash (birthday attack). As an impact it is known to affect confidentiality. The summary by CVE is:

The AWS S3 Crypto SDK sends an unencrypted hash of the plaintext alongside the ciphertext as a metadata field. This hash can be used to brute force the plaintext, if the hash is readable to the attacker. AWS now blocks this metadata field, but older SDK versions still send it.

The weakness was published 12/28/2022 as 35fa6ddf45c061e0f08d3a3b5119f8f4da38f6d1. The advisory is shared at github.com. This vulnerability is known as CVE-2022-2582 since 07/29/2022. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1600.001 for this issue.

Applying the patch 35fa6ddf45c061e0f08d3a3b5119f8f4da38f6d1 is able to eliminate this problem. The bugfix is ready for download at github.com.
