CVE-2022-45453

Adjacent data disclosure via weak TLS ciphers

Published May 18, 2023 · Updated Jan 22, 2025

Weak TLS cipher support in Acronis Cyber Protect 15 before build 30984 allows man-in-the-middle attackers to read protected data. The product accepts weak cipher suites on a TLS service, but Acronis has not identified the affected endpoint, suites, or cryptographic weakness. Exploitation requires adjacent-network access and high-complexity interception; the published impact is disclosure without alteration or interruption.
