CVE-2025-29455 is a medium-severity vulnerability identified in the Personal Management System version 1.4.65. The vulnerability allows a remote attacker to obtain sensitive information through the 'Travel Ideas' function. The vulnerability is classified under CWE-918, which corresponds to Server-Side Request Forgery (SSRF). SSRF vulnerabilities occur when an application fetches a remote resource without properly validating user-supplied URLs, potentially allowing attackers to induce the server to make unintended requests. In this case, the attacker can remotely exploit the 'Travel Ideas' feature to retrieve sensitive data from the system or internal network resources. The CVSS 3.1 base score is 6.5, indicating a medium severity level. The attack vector is network-based (AV:N), requiring no privileges (PR:N) and no user interaction (UI:N), but the attack complexity is high (AC:H), meaning exploitation requires specific conditions or knowledge. The impact on confidentiality is high (C:H), while integrity is low (I:L), and availability is not affected (A:N). No known exploits are currently reported in the wild, and no patches or vendor information are provided. The lack of vendor and product details limits precise identification, but the vulnerability's nature suggests it targets a personal management system application that likely handles user data and travel-related information.

For European organizations, this vulnerability poses a significant risk to confidentiality, especially for entities that use the affected Personal Management System or similar software for managing personal or travel-related data. Unauthorized disclosure of sensitive information could lead to privacy violations, regulatory non-compliance (e.g., GDPR), and reputational damage. The high confidentiality impact means that attackers could access internal data or metadata that may include personal identifiable information (PII), travel plans, or internal network details. Although the integrity and availability impacts are low or none, the exposure of sensitive data can facilitate further attacks such as social engineering or targeted intrusions. Organizations in sectors like travel, human resources, and personal data management are particularly at risk. The high attack complexity reduces the likelihood of widespread exploitation but does not eliminate targeted attacks, especially against high-value targets.

Given the absence of vendor patches, European organizations should implement the following specific mitigations: 1) Conduct a thorough inventory to identify any deployments of Personal Management System 1.4.65 or similar applications with a 'Travel Ideas' feature. 2) Implement strict network segmentation and firewall rules to restrict outbound HTTP/HTTPS requests from the affected application servers, limiting SSRF exploitation paths. 3) Use web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the 'Travel Ideas' function or unusual URL parameters. 4) Monitor application logs for anomalous access patterns or unexpected external requests initiated by the application. 5) Where possible, disable or restrict the 'Travel Ideas' feature until a patch or vendor guidance is available. 6) Employ input validation and URL whitelisting on any user-supplied URLs or parameters related to this function. 7) Educate IT and security teams about SSRF risks and ensure incident response plans include detection and containment strategies for such vulnerabilities.
