QuRouter: Improper Authentication
CVE-2024-13088 is a high-severity improper authentication vulnerability in QuRouter from QNAP, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 2.5.0.140 as the first without the flaw, so updating QuRouter to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.28% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
