CVE-2022-39029 is a medium-severity vulnerability affecting Smart eVision, a product developed by Smart eVision Information Technology Inc. The vulnerability is classified under CWE-200, which pertains to information exposure. Specifically, the issue arises from inadequate authorization controls on the database query functionality within the affected version 2022.02.21 of Smart eVision. This flaw allows a remote attacker who has general user privileges—meaning they are authenticated but not explicitly authorized—to access sensitive information that should be restricted. The vulnerability does not require user interaction and can be exploited remotely over the network (AV:N), with low attack complexity (AC:L). The attacker only needs privileges equivalent to a general user (PR:L), but no elevated privileges or administrative access are necessary. The impact is primarily on confidentiality (C:H), with no impact on integrity or availability. There are no known exploits in the wild at the time of publication, and no patches have been linked yet. The vulnerability was published on September 28, 2022, and has a CVSS v3.1 base score of 6.5, indicating a medium severity level. The root cause is insufficient authorization checks on database queries, which could lead to unauthorized data disclosure if exploited.

For European organizations using Smart eVision, this vulnerability could lead to unauthorized disclosure of sensitive data stored or processed by the product. Since the attacker only needs general user privileges, any compromised or malicious user account could be leveraged to extract confidential information, potentially including personal data, business-critical information, or intellectual property. This exposure could result in violations of data protection regulations such as the EU's GDPR, leading to legal and financial repercussions. Additionally, the unauthorized access could undermine trust in the affected systems and damage organizational reputation. The lack of impact on integrity and availability means the threat is primarily data leakage rather than system disruption, but the sensitivity of the exposed information could still have serious consequences. Organizations in sectors with high data sensitivity, such as finance, healthcare, and critical infrastructure, may face elevated risks.

European organizations should implement the following specific mitigations: 1) Immediately review and restrict user privileges within Smart eVision to the minimum necessary, ensuring that general users do not have access to sensitive database query functions. 2) Monitor and audit database query logs and user activities for unusual or unauthorized access patterns to detect potential exploitation attempts. 3) Apply network segmentation and access controls to limit exposure of Smart eVision systems to only trusted users and networks. 4) Engage with Smart eVision Information Technology Inc. to obtain patches or updates addressing this vulnerability as soon as they become available. 5) If patches are not yet available, consider temporary compensating controls such as disabling or restricting the vulnerable database query functions or deploying Web Application Firewalls (WAFs) with rules to detect and block suspicious query requests. 6) Conduct security awareness training for users to recognize and report suspicious activities. 7) Regularly review and update authorization policies and perform penetration testing to verify that authorization controls are effective.
