CVE-2025-29450 is a medium-severity vulnerability identified in the Twonav software version 2.1.18-20241105. The vulnerability is classified under CWE-918, which relates to server-side request forgery (SSRF) or similar issues that allow an attacker to manipulate server-side components to access unauthorized information. In this case, the flaw resides within the site settings component of Twonav, enabling a remote attacker to obtain sensitive information without requiring any authentication or user interaction. The CVSS 3.1 base score of 6.5 reflects a network attack vector (AV:N), high attack complexity (AC:H), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), high impact on confidentiality (C:H), low impact on integrity (I:L), and no impact on availability (A:N). This means an attacker can remotely exploit the vulnerability to disclose sensitive data, potentially including configuration details or credentials, but cannot modify or disrupt the system's operation. No known exploits are currently reported in the wild, and no patches or vendor advisories are available at this time. The lack of vendor and product information limits the ability to precisely identify affected environments, but the vulnerability's nature suggests it targets a network-exposed component that handles site settings, possibly in a web or mapping application context given the Twonav name. The high confidentiality impact combined with no authentication required makes this a significant information disclosure risk, especially if the exposed data includes credentials or internal configuration details that could facilitate further attacks.

For European organizations using Twonav 2.1.18-20241105, this vulnerability poses a risk of sensitive information leakage, which could include internal network configurations, credentials, or other critical data stored in site settings. Such information disclosure can facilitate lateral movement, targeted phishing, or further exploitation by adversaries. Sectors relying on Twonav for navigation, mapping, or geospatial data management—such as logistics, transportation, defense, and emergency services—may face operational risks if attackers leverage disclosed information to compromise systems or disrupt services. The medium severity and high confidentiality impact mean that while immediate disruption is unlikely, the breach of sensitive data could lead to long-term security consequences, including intellectual property theft or exposure of strategic operational details. Given the lack of patches and the high attack complexity, exploitation may currently be limited, but the absence of authentication requirements increases the threat surface. European organizations with network-exposed Twonav instances should consider this vulnerability a priority for risk assessment and mitigation to prevent potential data breaches.

1. Immediate network-level controls: Restrict access to the Twonav site settings component by implementing firewall rules or network segmentation to limit exposure to trusted IP addresses only. 2. Monitor and log access: Enable detailed logging on Twonav instances to detect unusual or unauthorized access attempts to the site settings component. 3. Apply virtual patching: Use web application firewalls (WAFs) or intrusion prevention systems (IPS) to detect and block suspicious requests targeting the site settings functionality. 4. Vendor engagement: Proactively contact Twonav vendors or support channels to obtain official patches or guidance, and subscribe to security advisories for timely updates. 5. Configuration review: Audit and minimize sensitive information stored in site settings to reduce the impact of potential disclosure. 6. Incident response readiness: Prepare response plans for potential information disclosure incidents, including forensic analysis and notification procedures. 7. Update policy: Incorporate this vulnerability into organizational risk management frameworks and vulnerability scanning routines to ensure ongoing awareness and remediation tracking.
