Impact
An incorrect permission assignment for a critical resource, specifically a world‑writable crontab path that is monitored and executed by a root‑owned process, allows a local attacker who has obtained a user account to gain root privileges on the system. The flaw is a classic inappropriate permissions issue (CWE‑732).
Affected Systems
The vulnerability affects QNAP Systems Inc. Notes Station 3, specifically versions prior to 3.9.11. The issue is fixed in Notes Station 3 3.9.11 and later.
Risk and Exploitability
The CVSS score of 8.5 reflects a high severity, while the EPSS score of less than 1% indicates a low probability of exploitation at this time. The vulnerability is not listed in the CISA KEV catalog. Exploitation requires local access and an existing user account; once compromised, the attacker can execute arbitrary commands as root. The limited scope to local users reduces the overall exploitability but the impact remains significant due to elevated privileges.
