Acronis Agent: Improper Certificate Validation
CVE-2022-45458 is a high-severity improper certificate validation vulnerability in Acronis Agent from Acronis, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 29633 as the first without the flaw, so updating Acronis Agent to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.35% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Acronis Agent to 29633 or a later version.
- Update Acronis Cyber Protect 15 to 30984 or a later version.
- Update Agent to c22.05 or a later version.
- Read the advisory on security-advisory.acronis.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Improper Certificate Validation

How developers prevent this class of flaw
- Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
- If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
