CVE-2025-27223 identifies a cryptographic vulnerability in TRUfusion Enterprise versions through 7.10.4.0, where the encrypted COOKIEID used as an authentication token is generated using a static encryption key. This static key usage violates secure cryptographic practices, as it enables attackers to forge valid authentication cookies without needing any prior credentials or user interaction. The affected endpoints, such as /trufusionPortal/getProjectList, rely solely on the encrypted COOKIEID for authentication, exposing sensitive internal information once the cookie is forged. The vulnerability is classified under CWE-1004, which relates to using static keys in cryptographic operations. The CVSS v3.1 score of 7.5 reflects a high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and a high impact on confidentiality (C:H) but no impact on integrity or availability. No patches or known exploits are currently available, but the static key flaw presents a straightforward attack path for adversaries. The vulnerability's root cause is the improper cryptographic design that fails to use dynamic or session-based keys, undermining the authentication mechanism's security.

For European organizations, this vulnerability poses a significant risk to the confidentiality of sensitive internal data managed through TRUfusion Enterprise. Attackers can remotely forge authentication cookies and access project lists or other sensitive information without detection. This could lead to data leaks, exposure of proprietary or personal data, and potential compliance violations under GDPR due to unauthorized data access. While integrity and availability are not directly impacted, the breach of confidentiality alone can damage organizational reputation, result in financial penalties, and facilitate further attacks leveraging the exposed information. Organizations in sectors such as manufacturing, engineering, or project management that rely on TRUfusion Enterprise for internal collaboration are particularly vulnerable. The absence of required privileges or user interaction lowers the barrier for exploitation, increasing the likelihood of attacks if the vulnerability is not remediated promptly.

Organizations should immediately audit their TRUfusion Enterprise deployments to identify affected versions. Since no official patches are available, temporary mitigations include disabling or restricting access to vulnerable endpoints like /trufusionPortal/getProjectList via network controls or web application firewalls. Implement multi-factor authentication (MFA) on all sensitive endpoints to reduce reliance on cookie-based authentication. Review and update the cookie encryption mechanism to replace the static key with dynamic, per-session keys or use established secure token standards such as JWT with proper signing and expiration. Monitor logs for unusual access patterns indicative of forged cookie usage. Engage with the vendor for timely patch releases and apply updates as soon as they become available. Additionally, conduct security awareness training for administrators to recognize and respond to potential exploitation attempts.
