Summary

CVE-2025-14349 is a high-severity Privilege Defined With Unsafe Actions (CWE-267) vulnerability in Uni-Yaz Flexcity. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 10.3th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 AC-14 (Permitted Actions Without Identification or Authentication) and AC-3 (Access Enforcement).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploitation for Privilege Escalation (T1068). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-3 Access Enforcement good match

prevent

Enforces approved authorizations preventing access to functionality not properly constrained by ACLs and blocking privilege escalation.

AC-6 Least Privilege good match

prevent

Limits privileges to the minimum necessary, mitigating privilege escalation from low-privileged access via unsafe actions.

AC-14 Permitted Actions Without Identification or Authentication good match

prevent

Defines and restricts critical functions performable without identification or authentication, directly addressing the missing authentication vulnerability.

Why these techniques?

Missing auth and unsafe privilege actions directly enable remote exploitation for privilege escalation from low-priv network access.

Deeper analysisAI

CVE-2025-14349 is a Privilege Defined With Unsafe Actions and Missing Authentication for Critical Function vulnerability in Universal Software Inc.'s FlexCity/Kiosk software. It enables Accessing Functionality Not Properly Constrained by ACLs, leading to privilege escalation. The issue affects FlexCity/Kiosk versions from 1.0 up to but not including 1.0.36. The vulnerability is associated with CWE-267 (Privilege Defined With Unsafe Actions) and CWE-306 (Missing Authentication for Critical Function), and it has a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

An attacker with low privileges (PR:L) can exploit this vulnerability over the network (AV:N) with low complexity (AC:L) and no user interaction required (UI:N). Successful exploitation allows the attacker to achieve high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H) without changing scope (S:U), typically resulting in full privilege escalation from an initial low-privileged access.

Mitigation involves upgrading to FlexCity/Kiosk version 1.0.36 or later, as the vulnerability affects all prior versions from 1.0. Additional guidance is available in the advisory at https://www.usom.gov.tr/bildirim/tr-26-0065.
