CVE-2025-29454 is a vulnerability identified in the Personal Management System version 1.4.65, categorized under CWE-918, which relates to server-side request forgery (SSRF) or similar indirect access flaws. The vulnerability allows a remote attacker to exploit the Upload function to obtain sensitive information without requiring any authentication or user interaction. The CVSS 3.1 base score is 6.5, indicating a medium severity level. The attack vector is network-based (AV:N), but the attack complexity is high (AC:H), meaning exploitation requires specific conditions or knowledge. No privileges are required (PR:N), and no user interaction is necessary (UI:N), which increases the risk of automated or remote exploitation. The scope remains unchanged (S:U), and the impact is primarily on confidentiality (C:H), with limited impact on integrity (I:L) and no impact on availability (A:N). The vulnerability likely arises from improper validation or sanitization in the Upload function, allowing attackers to access sensitive data that should be protected. No patches or vendor information are currently available, and no known exploits have been reported in the wild as of the publication date (April 17, 2025).

For European organizations using the affected Personal Management System 1.4.65, this vulnerability poses a significant risk to the confidentiality of sensitive personal or organizational data managed within the system. Given that the vulnerability can be exploited remotely without authentication or user interaction, attackers could potentially extract confidential information such as employee records, personal identifiable information (PII), or internal management data. This could lead to privacy violations, regulatory non-compliance (e.g., GDPR breaches), reputational damage, and potential financial penalties. The limited impact on integrity and no impact on availability suggest that while data may be exposed, it is less likely to be altered or deleted through this vulnerability. However, the high confidentiality impact alone is critical for sectors handling sensitive personal data, such as HR departments, healthcare providers, and government agencies. The high attack complexity may reduce the likelihood of widespread exploitation but does not eliminate the risk, especially from skilled threat actors targeting specific organizations.

Given the absence of official patches or vendor guidance, European organizations should implement the following specific mitigations: 1) Restrict network access to the Personal Management System's Upload function by applying strict firewall rules and network segmentation to limit exposure to trusted IP addresses only. 2) Monitor and log all upload requests and related activities to detect anomalous or suspicious patterns indicative of exploitation attempts. 3) Employ Web Application Firewalls (WAFs) with custom rules to detect and block malformed or suspicious upload requests that may attempt to exploit this vulnerability. 4) Conduct a thorough review and hardening of the Upload function, including input validation and sanitization, to prevent unauthorized data access. 5) If feasible, temporarily disable or restrict the Upload functionality until a patch or official fix is available. 6) Educate IT and security teams about this vulnerability to ensure rapid incident response if exploitation is detected. 7) Prepare for incident response by identifying sensitive data locations within the system and ensuring backups and data recovery plans are in place.
