| CVE ID | CVE-2025-62848 |
| CVSS SCORE | 5.5, AV:A/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L |
| AFFECTED VENDORS |
QNAP |
| AFFECTED PRODUCTS |
TS-453E |
| VULNERABILITY DETAILS |
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of QNAP TS-453E devices. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the handling of the format parameter provided to the conn_log_tool executable. The issue results from the lack of proper validation of a user-supplied string before using it as a format specifier. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of admin. |
