CVE-2022-39031 is a medium-severity vulnerability classified under CWE-200 (Information Exposure) affecting Smart eVision software developed by Smart eVision Information Technology Inc. The vulnerability arises from insufficient authorization controls in the task acquisition function of the product version 2022.02.21. Specifically, an unauthorized remote attacker can exploit this flaw to obtain the Session IDs of other general users without requiring any authentication or user interaction. The CVSS v3.1 base score is 5.3, reflecting a network attack vector with low attack complexity, no privileges required, and no user interaction needed. The impact is limited to confidentiality, as the attacker can only acquire session identifiers, which may enable session hijacking or unauthorized access if combined with other vulnerabilities or weaknesses. There is no indication of integrity or availability impact. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was published on September 28, 2022, and assigned by twcert with enrichment from CISA. The lack of proper authorization checks in the task acquisition function suggests a design or implementation flaw in access control mechanisms within the Smart eVision platform.

For European organizations using Smart eVision, this vulnerability poses a moderate risk primarily to confidentiality. Exposure of session IDs can lead to session hijacking attacks, allowing attackers to impersonate legitimate users and potentially access sensitive information or perform unauthorized actions within the application. This risk is heightened in environments where session management is weak or where multi-factor authentication is not enforced. Although the vulnerability does not directly affect integrity or availability, the compromise of user sessions can indirectly lead to data breaches or unauthorized data manipulation. Organizations in sectors with high privacy and data protection requirements, such as finance, healthcare, and critical infrastructure, may face regulatory and reputational consequences if exploited. The absence of known exploits reduces immediate risk, but the ease of exploitation (no authentication or user interaction required) means attackers could develop exploits rapidly once the vulnerability is publicly known.

European organizations should implement the following specific mitigations: 1) Immediately review and restrict access controls on the task acquisition function within Smart eVision to ensure proper authorization checks are enforced. 2) Monitor network traffic and application logs for unusual access patterns or repeated attempts to acquire session IDs. 3) Enforce strong session management practices, including short session lifetimes, secure cookie attributes (HttpOnly, Secure, SameSite), and session invalidation upon logout. 4) Deploy multi-factor authentication (MFA) to reduce the impact of session hijacking. 5) If possible, isolate Smart eVision deployments within segmented network zones with strict firewall rules to limit exposure. 6) Engage with the vendor for patches or updates addressing this vulnerability and apply them promptly once available. 7) Conduct security assessments and penetration testing focused on session management and authorization controls in Smart eVision environments. 8) Educate users about the risks of session hijacking and encourage secure usage practices.
