CVE-2025-62013 identifies a missing authorization vulnerability in POSIMYTH's UiChemy software, affecting all versions up to and including 4.0.0. This vulnerability arises when the application fails to properly enforce authorization checks on certain functions or resources, allowing users with low privileges to access data or operations they should not be permitted to. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N) indicates that the attack can be performed remotely over the network with low complexity and requires the attacker to have low privileges but no user interaction is needed. The impact is limited to confidentiality, meaning unauthorized information disclosure is possible, but integrity and availability remain unaffected. No known exploits have been reported in the wild, and no patches have been released at the time of this report. The vulnerability could be exploited by malicious insiders or external attackers who have obtained low-level access credentials, potentially leading to unauthorized data access. The absence of patches necessitates immediate risk mitigation through compensatory security controls and monitoring.

For European organizations, this vulnerability poses a risk of unauthorized data disclosure, which could lead to exposure of sensitive business or personal information. Sectors such as finance, healthcare, and government that rely on UiChemy for critical operations may face compliance and reputational risks if confidential data is leaked. Although the vulnerability does not allow modification or disruption of services, the breach of confidentiality could facilitate further attacks or insider threats. The remote exploitability and lack of required user interaction increase the likelihood of exploitation, especially in environments where low-privilege accounts are widely used or insufficiently monitored. Organizations with inadequate access controls or network segmentation may be more vulnerable. The medium severity rating suggests a moderate but non-negligible threat that should be addressed promptly to avoid escalation.

1. Conduct a thorough review of access control policies within UiChemy to ensure that authorization checks are correctly implemented and enforced for all sensitive functions and data. 2. Implement strict role-based access control (RBAC) to minimize the privileges assigned to users, especially limiting low-privilege accounts from accessing sensitive resources. 3. Apply network segmentation to isolate UiChemy servers from less trusted network zones, reducing the attack surface. 4. Monitor logs and access patterns for unusual or unauthorized access attempts, using SIEM tools to detect potential exploitation attempts early. 5. Until an official patch is released, consider deploying web application firewalls (WAFs) or intrusion prevention systems (IPS) with custom rules to block suspicious requests targeting UiChemy endpoints. 6. Educate administrators and users about the vulnerability and encourage prompt reporting of anomalies. 7. Plan for rapid deployment of patches once available and maintain an up-to-date inventory of affected systems to prioritize remediation.
