CVE-2025-67282 identifies multiple authorization bypass vulnerabilities affecting TIM BPM Suite and TIM FLOW products through version 9.1.2. Authorization bypass occurs when an application fails to properly enforce access control policies, allowing users to perform actions beyond their assigned privileges. In this case, low-privileged users can exploit these vulnerabilities to download password hashes of other users, which could facilitate offline password cracking and credential compromise. Additionally, attackers can access work items assigned to other users, potentially exposing sensitive business process data. They can also modify restricted content within workflows, undermining process integrity and potentially causing operational disruptions. The ability to change the application logo and manipulate other users' profiles indicates a lack of proper role-based access control and could be used for social engineering or to confuse legitimate users. These vulnerabilities collectively indicate systemic weaknesses in the access control mechanisms of TIM BPM Suite and TIM FLOW. Although no public exploits are known, the impact of successful exploitation could be severe, enabling privilege escalation, data leakage, and disruption of business workflows. The lack of a CVSS score suggests the vulnerability is newly published and pending further analysis. Organizations using these products should conduct thorough access control reviews and monitor for suspicious activities related to user account manipulation and workflow changes.

For European organizations, the impact of CVE-2025-67282 could be substantial, especially for those relying on TIM BPM Suite or TIM FLOW for critical business process management. Unauthorized access to password hashes risks credential theft and lateral movement within corporate networks, potentially leading to broader compromise. Exposure and modification of work items and workflow content can disrupt business operations, cause data integrity issues, and lead to compliance violations under regulations like GDPR if personal or sensitive data is involved. Manipulation of user profiles and application branding could facilitate phishing or social engineering attacks, undermining user trust. The vulnerabilities could also affect availability if workflow processes are corrupted or blocked. Given the central role of BPM tools in coordinating enterprise workflows, exploitation could have cascading effects across multiple departments and services. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, may face heightened risks and regulatory scrutiny.

Immediate mitigation steps include restricting access to TIM BPM Suite and TIM FLOW to trusted users only and enforcing the principle of least privilege rigorously. Organizations should monitor logs for unusual access patterns, such as low-privileged users accessing or modifying other users' data or workflow content. Network segmentation can limit the exposure of BPM systems to internal users only. Until patches or updates are released, consider implementing compensating controls such as multi-factor authentication (MFA) for all users, especially those with elevated privileges. Conduct a thorough audit of user permissions and remove unnecessary privileges. If possible, disable or restrict features that allow modification of application branding or user profiles. Engage with the vendor for timely patches or official guidance. Additionally, educate users about the risks of phishing and social engineering that could exploit altered application branding. Regularly back up workflow configurations and data to enable recovery in case of tampering.
