CVE-2021-44035 is a vulnerability identified in Wolters Kluwer TeamMate AM version 12.4 Update 1. The issue arises from improper handling of attachment uploads within the application. Specifically, an authenticated user can exploit this flaw to download and execute malicious files on the system. This vulnerability requires the attacker to have valid credentials (authenticated user) and involves user interaction (uploading and downloading attachments). The vulnerability impacts confidentiality and integrity by allowing unauthorized execution of potentially harmful code, which could lead to further compromise of the system or data leakage. The CVSS 3.1 base score is 4.4 (medium severity), reflecting that the attack complexity is high (AC:H), network attack vector is none (AV:N is actually network but the vector is local or network?), privileges required are low (PR:L), scope is changed (S:C), and user interaction is required (UI:R). The vulnerability does not appear to have known exploits in the wild, and no patches or vendor advisories are currently linked. The lack of detailed product and vendor information limits the ability to fully assess the environment but the affected product is known to be TeamMate AM, an audit management software widely used in financial and compliance sectors.

For European organizations, especially those in finance, auditing, and compliance sectors where TeamMate AM is commonly deployed, this vulnerability could allow malicious insiders or compromised users to execute arbitrary code by uploading malicious attachments. This could lead to unauthorized data access, manipulation of audit records, or disruption of audit processes, undermining regulatory compliance and internal controls. Given the sensitivity of audit data, exploitation could result in reputational damage, regulatory penalties under GDPR or other frameworks, and potential financial loss. The requirement for authentication and user interaction somewhat limits the attack surface but insider threats or compromised credentials remain a significant risk. The changed scope (S:C) indicates that the vulnerability can affect resources beyond the initially vulnerable component, potentially impacting broader system integrity.

Organizations using TeamMate AM 12.4 Update 1 should immediately review user permissions to ensure that only trusted personnel have attachment upload capabilities. Implement strict access controls and monitor for unusual upload/download activities. Since no patch links are provided, contact Wolters Kluwer support for any available updates or workarounds. Employ application-layer security controls such as file type validation, sandboxing of uploaded files, and endpoint protection to detect and block malicious payloads. Conduct regular audits of user activity logs to detect potential exploitation attempts. Additionally, enforce multi-factor authentication to reduce the risk of credential compromise. If possible, isolate the audit management system from general user networks to limit exposure. Finally, educate users about the risks of uploading and executing untrusted files.
