CVE-2024-8074 Overview
CVE-2024-8074 is a missing authentication and authorization vulnerability in Nomysoft Informatics Nomysem. The flaw allows attackers to collect data provided by users without proper access controls. The issue affects all Nomysem versions before 13.10.2024. The vulnerability is categorized under [CWE-306] Missing Authentication for Critical Function. Network-based attackers can exploit this weakness with low privileges and no user interaction, exposing confidential user data and impacting system integrity.
Critical Impact
Attackers can access and collect sensitive user-submitted data through unauthenticated requests to critical Nomysem functions.

Technical Details for CVE-2024-8074
Vulnerability Analysis
The vulnerability resides in Nomysem's request handling logic for functions that process user-provided data. Critical endpoints lack authentication enforcement, allowing remote callers to interact with sensitive operations directly. The flaw also reflects missing authorization checks, meaning even when a session exists, the application fails to validate whether the caller has rights to the requested resource. Attackers can issue crafted network requests to retrieve data that should be restricted to authorized users.
Root Cause
The root cause is the absence of authentication gates on critical functions, classified as [CWE-306]. The application exposes data-collection endpoints without verifying caller identity or permissions. This design flaw effectively treats sensitive operations as public, breaking the confidentiality boundary expected for user records. Authorization controls that should validate object ownership or role membership are not invoked along the affected code path.
Attack Vector
An attacker reaches the vulnerability over the network by sending requests to the exposed Nomysem function. No credentials or social engineering are required to trigger data collection. The attacker can enumerate or harvest user-submitted records by interacting with the unauthenticated endpoint. Because the issue is reachable from any network-connected client, internet-exposed Nomysem instances face the highest risk.
No verified exploit code is publicly available. See the USOM Security Notification for vendor-coordinated details.
Detection Methods for CVE-2024-8074
Indicators of Compromise
- Unauthenticated HTTP requests to Nomysem data-handling endpoints from external IP addresses
- High-volume sequential requests indicating data enumeration against user-record endpoints
- Application logs showing successful responses to requests lacking session or token headers
Detection Strategies
- Inspect Nomysem application access logs for requests to sensitive endpoints with missing or empty Authorization headers
- Deploy web application firewall rules that flag requests targeting Nomysem data endpoints without authentication cookies or tokens
- Correlate outbound responses containing personally identifiable information with the absence of an authenticated session identifier
Monitoring Recommendations
- Enable verbose request logging on the Nomysem web tier and forward logs to a centralized SIEM
- Alert on response volume spikes from data-collection endpoints during off-hours
- Monitor for repeated requests from a single source against user-data URIs, indicating scraping behavior
How to Mitigate CVE-2024-8074
Immediate Actions Required
- Upgrade Nomysem to version 13.10.2024 or later immediately
- Restrict network access to Nomysem administrative and data endpoints using firewall or VPN controls
- Audit application logs for prior unauthenticated access to sensitive functions
Patch Information
Nomysoft Informatics addressed the vulnerability in Nomysem release 13.10.2024. Administrators should apply the vendor-supplied update following the guidance referenced in the USOM Security Notification. Verify the running version after upgrade and confirm authentication is enforced on previously exposed endpoints.
Workarounds
- Place Nomysem behind an authenticating reverse proxy that enforces session validation before requests reach the application
- Block internet exposure of Nomysem endpoints and require VPN access for legitimate users
- Apply temporary WAF rules to deny requests to data-collection endpoints that lack valid authentication tokens
