CVE-2025-14403 is a vulnerability identified in PDFsam Enhanced version 7.0.76.15222, categorized under CWE-356, which concerns insufficient user interface warnings for unsafe actions. The vulnerability specifically involves the 'Launch' action feature within the software, which allows execution of scripts or commands without adequately warning the user of potential risks. This design flaw enables remote attackers to craft malicious PDF files or web pages that, when opened or visited by a user, trigger the execution of arbitrary code in the context of the current user. The attack vector requires user interaction, such as opening a malicious file or clicking a link, but does not require prior authentication or elevated privileges. The vulnerability impacts confidentiality, integrity, and availability by allowing attackers to run arbitrary code, potentially leading to data theft, system compromise, or disruption of services. The CVSS 3.0 score of 7.8 reflects high severity, with attack vector local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no exploits have been reported in the wild, the vulnerability's nature and severity make it a significant risk for affected users. The lack of patch links suggests that remediation may require vendor updates or configuration changes to mitigate the risk.

For European organizations, this vulnerability poses a significant risk, especially for those relying on PDFsam Enhanced for document management and processing. Successful exploitation can lead to remote code execution with the privileges of the logged-in user, potentially allowing attackers to access sensitive information, modify or delete data, install malware, or disrupt business operations. Given the user interaction requirement, phishing or social engineering campaigns could be leveraged to increase exploitation likelihood. The impact is heightened in environments where users have elevated privileges or where PDFsam Enhanced is integrated into critical workflows. Confidentiality breaches could expose personal or corporate data, violating GDPR and other data protection regulations, leading to legal and financial repercussions. Integrity and availability impacts could disrupt document workflows, affecting productivity and operational continuity. The absence of known exploits in the wild provides a window for proactive mitigation, but organizations should not delay remediation efforts.

1. Immediately update PDFsam Enhanced to the latest version once a patch is released by the vendor addressing CVE-2025-14403. 2. Until a patch is available, restrict or disable the 'Launch' action feature within PDFsam Enhanced if configurable. 3. Implement strict email and web filtering to block or quarantine potentially malicious PDF files and links. 4. Conduct user awareness training emphasizing the risks of opening unsolicited files or clicking unknown links, highlighting this specific vulnerability's exploitation method. 5. Employ endpoint protection solutions capable of detecting and blocking suspicious script execution triggered by PDF files. 6. Monitor logs and network traffic for unusual activity related to PDFsam Enhanced usage or script execution. 7. Apply the principle of least privilege to user accounts to limit the impact of potential code execution. 8. Consider application whitelisting to prevent unauthorized code execution initiated by PDFsam Enhanced. 9. Regularly review and update incident response plans to include scenarios involving PDF-related remote code execution attacks.
