CVE-2022-45457

Data disclosure and manipulation via improper certificate validation

Published May 18, 2023 · Updated Jan 22, 2025

Improper certificate validation in Windows Acronis Agent before build 29633 and Cyber Protect 15 before build 30984 lets attackers read or alter data. Acronis has not disclosed the affected certificate-checking locus or which certificate property is accepted incorrectly. Exploitation requires an unauthenticated adjacent-network position and enables sensitive-information disclosure or manipulation without service interruption.
