CVE-2022-22564

21
FAUCET Score

CVE-2022-22564 describes a cryptographic vulnerability in Dell EMC Unity, Unity XT, and UnityVSA operating environments prior to version 5.2.0.0.5.173. This medium-severity flaw (CVSS 5.9) allows a remote, unauthenticated attacker to perform Man-in-the-Middle attacks due to the use of a broken cryptographic algorithm, potentially leading to the disclosure of sensitive information. While no active exploitation, public exploit code, or significant community discussion has been observed, organizations using affected versions should prioritize patching to mitigate this risk.
