## Technical details

A path traversal vulnerability (CWE-22) exists in QNAP License Center due to improper limitation of a pathname to a restricted directory. An attacker with high privileges (administrator account) can exploit this via the network to bypass directory restrictions and read the contents of unexpected files or system data. While the initial advisory mentions a 'local' attacker, the CVSS 4.0 vector provided by the vendor (AV:N) indicates the vulnerability is reachable over the network. The issue is resolved in License Center version 1.9.56 and later.
