CVE-2025-14349
Access Control in Uni-Yaz Flexcity 1.0 – 1.0.36
Raw vector
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:HSummary
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 Exploit Public-Facing Application (T1190); ranked at the 29th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-14 (Permitted Actions Without Identification or Authentication) and AC-6 (Least Privilege) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
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.

Mitigating Controls (NIST 800-53 r5) AI
Directly mandates unique identification and authentication of users before access to functions requiring identity.
Extends the same authentication requirement to non-organizational users accessing critical functionality.
Requires authentication of services before they can invoke or expose critical functions.
Explicitly identifies and limits actions permitted without authentication, preventing critical functions from being exposed.
Least privilege directly requires that privileges grant only the minimal actions needed, preventing definition of overly broad privileges that include unintended unsafe operations.
Access enforcement requires prior authentication before any authorization decision for critical functions.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Directly requires authentication of users/services/hardware, which eliminates missing authentication for critical functions.
Defining and enforcing least-privilege permissions directly reduces the chance that a privilege permits unintended unsafe actions.
Managing identities and credentials is a prerequisite for authentication but does not itself enforce it on critical functions.
Protecting networks from unauthorized access can be undermined by missing authentication but does not address the root authentication gap.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
The control explicitly calls for authentication before any critical function is reached, eliminating the possibility of bypassing authentication for high-value operations.
Use of privileged utility programs restricts dangerous tools but does not address unsafe actions within assigned privileges.
Access control policy can limit unsafe privilege use but does not define safe actions for each privilege.
Access rights assignment can restrict privileges to intended actions, yet does not guarantee the privilege itself is safe.
Segregation of duties reduces risk of unsafe actions by splitting privileges but does not address unsafe privilege definitions.
Mandating authentication requirements for critical functions at the requirements-gathering stage ensures that essential operations are not left unprotected by missing login or verification mechanisms.
