CVE-2020-10140· NVD / CVE Program· CNA certcc

Acronis True Image 2021 fails to properly set ACLs of the C:\ProgramData\Acronis directory.

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.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
