CVE-2025-1161 is a vulnerability identified in the Nomysem product by NomySoft Information Technology Training and Consulting Inc., classified under CWE-648, which pertains to the incorrect use of privileged APIs. This vulnerability allows an attacker to escalate privileges improperly by exploiting flaws in how the software handles privileged API calls. The CVSS v3.1 score of 7.1 indicates a high-severity issue with network attack vector (AV:N), high attack complexity (AC:H), requiring low privileges (PR:L) and user interaction (UI:R). The scope is unchanged (S:U), but the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). This means that an attacker who can interact with the system over the network and convince a user to perform an action could gain elevated privileges, potentially leading to full system compromise. The affected version is listed as '0', which likely indicates early or initial versions of Nomysem up to May 2025. No patches or exploits are currently publicly available, but the vulnerability is officially published and reserved since February 2025. The root cause lies in improper API usage that fails to enforce correct privilege boundaries, allowing privilege escalation vectors. This vulnerability could be exploited in environments where Nomysem is deployed, particularly if network access and user interaction are feasible.

For European organizations, the impact of CVE-2025-1161 could be significant, especially in sectors relying on Nomysem for critical operations. Privilege escalation vulnerabilities enable attackers to gain unauthorized administrative control, potentially leading to data breaches, system manipulation, or service disruption. Confidentiality breaches could expose sensitive personal or corporate data, violating GDPR and other data protection regulations. Integrity compromises could allow attackers to alter data or configurations, undermining trust and operational reliability. Availability impacts could disrupt services, causing operational downtime and financial loss. Organizations in finance, healthcare, government, and critical infrastructure sectors are particularly vulnerable due to the sensitive nature of their data and services. The requirement for user interaction and high attack complexity somewhat limits mass exploitation but targeted attacks remain a serious concern. The absence of known exploits currently provides a window for proactive mitigation.

1. Monitor NomySoft’s official channels for patches or updates addressing CVE-2025-1161 and apply them immediately upon release. 2. Restrict network access to Nomysem instances using firewalls and network segmentation to limit exposure to untrusted networks. 3. Implement strict user privilege management and least privilege principles to reduce the impact of potential privilege escalation. 4. Educate users on phishing and social engineering risks to minimize the chance of user interaction-based exploitation. 5. Deploy endpoint detection and response (EDR) solutions to identify anomalous privilege escalation attempts or suspicious API usage. 6. Conduct regular security audits and code reviews if custom integrations with Nomysem exist, ensuring privileged API calls are correctly handled. 7. Use application whitelisting and integrity monitoring to detect unauthorized changes to Nomysem or its environment. 8. Prepare incident response plans specifically addressing privilege escalation scenarios to enable rapid containment and remediation.
