CVE-2022-2582

18
FAUCET Score

CVE-2022-2582 describes a medium-severity vulnerability in the AWS S3 Crypto SDK where older versions transmit an unencrypted plaintext hash as metadata, potentially allowing brute-force attacks if readable by an attacker. This flaw affects the Amazon AWS Software Development Kit and has a CVSS score of 4.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N), indicating a network-based attack with low complexity and a potential impact on confidentiality. While AWS now blocks this metadata field, older SDK versions remain vulnerable. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.
