CVE-2025-23182 is a medium-severity vulnerability identified in UBtech's Freepass product, specifically affecting version 1.3.1807.1500. The vulnerability is categorized under CWE-203, which refers to an Observable Discrepancy. This type of weakness typically involves the system revealing differences in behavior or output that can be observed by an attacker, potentially allowing them to infer sensitive information or the internal state of the system. According to the CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N), the vulnerability can be exploited remotely over the network with low attack complexity, requires the attacker to have some level of privileges (PR:L), and does not require user interaction. The impact is limited to confidentiality (C:L), with no direct effect on integrity or availability. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability was reserved in January 2025 and published in May 2025, indicating recent discovery and disclosure. The lack of patches suggests that organizations using the affected version remain vulnerable until remediation is available. The observable discrepancy could allow an attacker with limited privileges to gather information that might facilitate further attacks or reconnaissance within the environment where Freepass is deployed.

For European organizations using UBtech Freepass version 1.3.1807.1500, this vulnerability poses a moderate risk primarily to confidentiality. Since Freepass is likely used in access control or authentication contexts (given the product name and vendor profile), leaking information through observable discrepancies could enable attackers to infer authentication states, user presence, or system configurations. This information leakage could aid in crafting more targeted attacks or bypassing security controls. While the vulnerability does not directly impact integrity or availability, the confidentiality loss could have regulatory implications under GDPR if personal data or authentication details are indirectly exposed. The requirement for low privileges to exploit means that insider threats or compromised accounts could leverage this vulnerability to escalate their knowledge of the system. The absence of user interaction and remote exploitability increases the risk surface. European organizations relying on Freepass for physical or logical access management should consider this vulnerability seriously, especially in sectors with high security requirements such as finance, critical infrastructure, or government.

Given the absence of an official patch, European organizations should implement compensating controls to mitigate the risk. These include: 1) Restricting access to the Freepass management interfaces and network segments to trusted and authenticated personnel only, minimizing the number of users with low privileges who could exploit the vulnerability. 2) Implementing network segmentation and strict firewall rules to limit exposure of Freepass systems to untrusted networks. 3) Enhancing monitoring and logging around Freepass usage to detect unusual access patterns or reconnaissance activities that may indicate exploitation attempts. 4) Conducting internal audits to identify and remove unnecessary privileged accounts to reduce the attack surface. 5) Engaging with UBtech support to obtain timelines for patches or updates and applying them promptly once available. 6) Considering temporary alternative access control measures if the risk is deemed unacceptable until a patch is released. 7) Training security teams to recognize signs of information leakage or anomalous behavior related to Freepass systems.
