CVE-2025-62978 identifies a missing authorization vulnerability in Kiotviet KiotViet Sync, a synchronization tool used primarily for retail and inventory management. The issue arises from incorrectly configured access control security levels that fail to properly enforce authorization checks. This flaw allows an attacker with at least some level of privileges (PR:L - low privileges) to remotely access certain functionalities or data that should be restricted, without requiring user interaction (UI:N). The vulnerability affects all versions up to and including 1.8.5. The CVSS vector indicates network attack vector (AV:N), low attack complexity (AC:L), privileges required (PR:L), no user interaction (UI:N), unchanged scope (S:U), limited confidentiality impact (C:L), and no impact on integrity or availability (I:N/A:N). Although no public exploits are known, the vulnerability could be leveraged to gain unauthorized access to sensitive information, potentially exposing business data. The lack of patches or mitigation links suggests that affected organizations need to proactively assess and secure their deployments. Given KiotViet's focus on retail and inventory synchronization, the vulnerability could impact business operations and data confidentiality if exploited.

For European organizations, the primary impact is unauthorized access to sensitive business data managed or synchronized by KiotViet Sync. This could lead to exposure of customer information, inventory details, or transactional data, undermining confidentiality. While the vulnerability does not affect data integrity or system availability, unauthorized data access can result in reputational damage, regulatory non-compliance (e.g., GDPR), and potential financial losses. Retailers and SMEs using KiotViet Sync as part of their supply chain or inventory management are particularly at risk. The remote exploitability and low complexity increase the likelihood of opportunistic attacks, especially if attackers gain low-level access through other means. The absence of known exploits provides a window for mitigation, but organizations should act promptly to prevent potential abuse. The impact is more pronounced in sectors with high data sensitivity and regulatory oversight.

European organizations should immediately conduct a thorough audit of access control configurations within KiotViet KiotViet Sync deployments to identify and remediate any improperly configured permissions. Restrict user privileges to the minimum necessary and enforce strict role-based access controls. Network segmentation and firewall rules should limit external access to the synchronization service to trusted hosts only. Implement continuous monitoring and logging of access attempts to detect unauthorized activities early. Since no official patches are currently available, consider deploying compensating controls such as multi-factor authentication for accessing the synchronization service and isolating the service within secure network zones. Engage with the vendor for updates and apply patches promptly once released. Additionally, conduct employee training to raise awareness about potential exploitation vectors related to access control weaknesses.
