CVE-2025-68912 identifies a path traversal vulnerability in Harmonic Design's HDForms product, affecting versions up to and including 1.6.1. Path traversal vulnerabilities occur when an application improperly restricts file path inputs, allowing attackers to navigate outside the intended directory structure. In this case, the vulnerability permits remote attackers to craft malicious requests that access files and directories beyond the application's restricted scope without requiring authentication or user interaction. The CVSS v3.1 score of 8.6 reflects a high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). The impact on confidentiality is high, as attackers can read sensitive files, while integrity and availability impacts are low but present. Although no exploits are currently known in the wild, the vulnerability poses a significant risk due to its ease of exploitation and potential to expose critical data. The lack of available patches at the time of publication necessitates immediate attention to alternative mitigations. This vulnerability highlights the importance of secure input validation and proper file system access controls within web applications handling file paths.

For European organizations, this vulnerability could lead to unauthorized disclosure of sensitive information, including configuration files, credentials, or personal data, potentially violating GDPR and other data protection regulations. Confidentiality breaches could result in reputational damage, regulatory fines, and loss of customer trust. The ability to read arbitrary files may also facilitate further attacks, such as privilege escalation or lateral movement within networks. Critical sectors such as finance, healthcare, and government using HDForms may face operational disruptions or targeted attacks exploiting this vulnerability. The low complexity and lack of authentication requirements increase the likelihood of exploitation by opportunistic attackers or advanced persistent threat groups. Additionally, the exposure of internal files could aid attackers in crafting more sophisticated attacks against European entities. The absence of known exploits currently provides a window for proactive defense, but the risk remains significant given the vulnerability's characteristics.

Organizations should immediately inventory their use of Harmonic Design HDForms and identify affected versions (up to 1.6.1). Until official patches are released, implement strict input validation to sanitize and canonicalize all file path inputs, ensuring that traversal sequences (e.g., '../') are blocked or neutralized. Employ web application firewalls (WAFs) with custom rules to detect and block path traversal attempts targeting HDForms endpoints. Restrict file system permissions for the HDForms application user to the minimum necessary, preventing access to sensitive directories and files outside the application scope. Monitor logs for unusual file access patterns indicative of exploitation attempts. Engage with Harmonic Design for timely patch releases and apply them promptly once available. Consider network segmentation to isolate HDForms servers from critical internal systems to limit potential lateral movement. Conduct security awareness training for IT staff to recognize and respond to exploitation indicators. Finally, review and update incident response plans to address potential breaches stemming from this vulnerability.
