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 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.

Acronis True Image prior to 2021 Update 4 for Windows allowed local privilege escalation due to improper soft link handling (issue 2 of 2).

Acronis True Image prior to 2021 Update 5 for Windows allowed local privilege escalation due to insecure folder permissions.

Acronis True Image prior to 2021 Update 4 for Windows allowed local privilege escalation due to improper soft link handling (issue 1 of 2).

Acronis True Image for Windows prior to 2021 Update 3 allowed local privilege escalation due to a DLL hijacking vulnerability in multiple components, aka an Untrusted Search Path issue.

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 through 2021 on macOS allows local privilege escalation from admin to root due to insecure folder permissions.

Acronis True Image for Mac before 2021 Update 4 allowed local privilege escalation due to insecure folder permissions.

Acronis True Image 2019 update 1 through 2020 on macOS allows local privilege escalation due to an insecure XPC service configuration.

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 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 up to and including version 2017 Build 8053 performs software updates using HTTP. Downloaded updates are only verified using a server-provided MD5 hash.

Acronis True Image Windows Agent 1.0.0.54 and earlier, included in Acronis True Image Enterprise Server 9.5.0.8072 and the other True Image packages, allows remote attackers to cause a denial of service (crash) via a malformed packet to port 9876, which triggers a NULL pointer dereference.

Acronis True Image Group Server 1.5.19.191 and earlier, included in Acronis True Image Enterprise Server 9.5.0.8072 and the other True Image packages, allows remote attackers to cause a denial of service (crash) via a packet with an invalid length field, which causes an out-of-bounds read.
