CVE-2024-8074 is a critical security vulnerability identified in Nomysoft Informatics' Nomysem software, affecting all versions prior to 13.10.2024. The vulnerability is classified under CWE-306 (Missing Authentication for Critical Function) and CWE-862 (Missing Authorization), indicating that certain critical functions within the software do not enforce proper authentication and authorization checks. Specifically, this flaw allows an attacker with limited privileges (PR:L) to remotely invoke a function that collects data as provided by users without requiring any user interaction (UI:N) or elevated privileges beyond limited access. The attack vector is network-based (AV:N) with low complexity (AC:L), meaning exploitation can be performed remotely with minimal effort. The vulnerability impacts confidentiality and integrity highly (VC:H, VI:H), as unauthorized data collection could lead to exposure or manipulation of sensitive information. The scope is limited (SI:L) to the vulnerable component, and no privileges are required to escalate beyond the initial limited access. The vulnerability is rated critical with a CVSS 4.0 score of 9.3, reflecting the severe risk posed. Although no known exploits have been reported in the wild, the absence of authentication and authorization controls on critical functions represents a significant security gap. Organizations using Nomysem should prioritize remediation to prevent potential data breaches or unauthorized data manipulation.

For European organizations, the impact of CVE-2024-8074 is substantial, particularly for those in sectors such as finance, healthcare, government, and critical infrastructure where Nomysem might be deployed for data collection or processing. The vulnerability allows attackers with limited access to bypass authentication and authorization controls, potentially leading to unauthorized data collection, exposure of sensitive user information, and manipulation of data integrity. This could result in regulatory non-compliance under GDPR due to data breaches, financial losses, reputational damage, and operational disruptions. The critical nature of the vulnerability means that even low-privileged insiders or external attackers who gain limited access could exploit this flaw to escalate their capabilities and compromise confidentiality and integrity of data. The absence of user interaction and the network-based attack vector increase the risk of automated or remote exploitation attempts. European organizations must consider the potential for targeted attacks exploiting this vulnerability, especially in environments where Nomysem is integrated with other critical systems.

1. Immediate mitigation involves applying vendor patches or updates once released for Nomysem versions prior to 13.10.2024. 2. Until patches are available, restrict network access to Nomysem interfaces to trusted internal networks only, using firewalls and network segmentation. 3. Implement strict access control policies limiting user privileges to the minimum necessary, ensuring no unauthorized users have access to critical functions. 4. Enable detailed logging and monitoring of all access to Nomysem, focusing on unusual or unauthorized attempts to invoke data collection functions. 5. Conduct regular security audits and penetration testing to identify and remediate any residual access control weaknesses. 6. Employ application-layer firewalls or web application firewalls (WAFs) to detect and block suspicious requests targeting the vulnerable functions. 7. Educate administrators and users about the risks associated with this vulnerability and the importance of following security best practices. 8. Prepare incident response plans to quickly address any exploitation attempts or breaches related to this vulnerability.
