Acronis True Image 2021

Acronis True Image prior to 2021 Update 4 for Windows, Acronis True Image prior to 2021 Update 5 for Mac, Acronis Agent prior to build 26653, Acronis Cyber Protect prior to build 27009 did not implement SSL certificate validation.

Acronis True Image 2019 update 1 through 2021 update 1 on macOS allows local privilege escalation due to an insecure XPC service configuration.

Acronis True Image 2021 includes an OpenSSL component that specifies an OPENSSLDIR variable as a subdirectory within C:\jenkins_agent\. Acronis True Image contains a privileged service that uses this OpenSSL component. Because unprivileged Windows users can create subdirectories off of the system root, a user can create the appropriate path to a specially-crafted openssl.cnf file to achieve arbitrary code execution with SYSTEM privileges.

Acronis True Image 2021 fails to properly set ACLs of the C:\ProgramData\Acronis directory. Because some privileged processes are executed from the C:\ProgramData\Acronis, an unprivileged user can achieve arbitrary code execution with SYSTEM privileges by placing a DLL in one of several paths within C:\ProgramData\Acronis.

Acronis True Image prior to 2021 Update 4 for Windows allowed local privilege escalation due to DLL hijacking.

Acronis True Image prior to 2021 Update 4 for Windows and Acronis True Image prior to 2021 Update 5 for macOS allowed an unauthenticated attacker (who has a local code execution ability) to tamper with the micro-service API.
