CVE-2023-44158

Information disclosure via insufficient token-field masking

Published Sep 27, 2023 · Updated Sep 23, 2024

Sensitive information disclosure in Acronis Cyber Protect 15 before build 35979 allows remote authenticated users to read token data. A token field is returned without sufficient masking, exposing sensitive credential material; Acronis has not identified the responsible component or operation publicly. Exploitation requires adjacent-network access and low privileges, and the documented consequence is limited to confidentiality loss.
