CVE-2022-30995: Sensitive information disclosure due to improper authentication.

Noroxi assessment

Priority: This week (action score 60/100)

A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
A ready-made attack tool exists and the flaw can be exploited over the network without an account, so priority is at least “This week”.
Probability of exploitation in the next 30 days: 3.2% (FIRST EPSS); higher than 88.3% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
Fixed version: Acronis Acronis Cyber Backup 12.5 16545; Acronis Acronis Cyber Protect 15 29486.

Don’t wait for the next maintenance window. Upgrade to Acronis Acronis Cyber Backup 12.5 16545; Acronis Acronis Cyber Protect 15 29486 or later.

Weakness class (CWE)

CWE-287 · Improper Authentication

CVSS vector

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

nvd-primary

Root cause

Authentication is added route by route instead of being enforced in one place. When a route added later bypasses the shared middleware, the session check never runs for it.

A representative example of this vulnerability class. Not the vendor's source code; it shows the faulty pattern and its fix.
