CVE-2025-29453 is a medium-severity vulnerability identified in the Personal Management System version 1.4.65, specifically within the 'my-contacts-settings' component. This vulnerability allows a remote attacker to obtain sensitive information without requiring any authentication or user interaction. The vulnerability is classified under CWE-918, which corresponds to Server-Side Request Forgery (SSRF). SSRF vulnerabilities enable attackers to induce the server-side application to make HTTP requests to arbitrary domains, potentially exposing internal resources or sensitive data. In this case, the attacker can exploit the my-contacts-settings component to retrieve sensitive information remotely. The CVSS v3.1 base score is 6.5, reflecting a medium severity level, with the vector indicating 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). No patches or known exploits are currently reported. The lack of vendor or product information limits the ability to precisely identify the affected environment, but the vulnerability's nature suggests it targets a personal management system application that handles contact information, potentially used in enterprise or organizational settings.

For European organizations, the primary impact of this vulnerability is the unauthorized disclosure of sensitive personal or contact information managed within the affected system. This could include personal identifiable information (PII), contact details, or other confidential data stored in the my-contacts-settings component. Such data leakage can lead to privacy violations, regulatory non-compliance (notably GDPR), reputational damage, and potential follow-on attacks such as phishing or social engineering. The medium severity and high confidentiality impact indicate that while the system's integrity and availability are minimally affected, the confidentiality breach alone can have significant consequences, especially for organizations handling sensitive customer or employee data. Given the remote exploitation capability without authentication or user interaction, attackers can operate stealthily and at scale, increasing the risk profile for organizations relying on this software. The absence of known exploits in the wild currently reduces immediate risk but does not preclude future exploitation attempts.

1. Immediate mitigation should include conducting a thorough inventory to identify any deployments of Personal Management System version 1.4.65 or similar versions containing the vulnerable my-contacts-settings component. 2. Since no official patches are currently available, organizations should implement network-level controls to restrict outbound HTTP requests from the affected system to only trusted domains, thereby limiting SSRF exploitation potential. 3. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious SSRF patterns targeting the my-contacts-settings component. 4. Monitor logs for unusual or unexpected outbound requests initiated by the Personal Management System, focusing on internal IP ranges or sensitive endpoints. 5. If feasible, isolate the affected system within segmented network zones to minimize lateral movement and data exposure. 6. Engage with the software vendor or community to obtain updates or patches as they become available. 7. Educate security teams to recognize indicators of SSRF exploitation and prepare incident response plans accordingly. These steps go beyond generic advice by focusing on network-level restrictions, monitoring, and segmentation tailored to SSRF vulnerabilities in the absence of immediate patches.
