CVE-2026-24728 is a critical security vulnerability identified in Internet Information Co., Ltd's DreamMaker software, specifically affecting versions released before October 22, 2025. The vulnerability arises from a missing authentication mechanism on the /servlet/baServer3 endpoint, which exposes administrative functions to unauthenticated remote attackers. This means that any attacker with network access to the affected service can invoke critical administrative operations without providing any credentials or undergoing any form of verification. The vulnerability is classified under CWE-306 (Missing Authentication for Critical Function), highlighting a fundamental security design flaw. The CVSS 4.0 base score of 9.3 reflects the high severity, with attack vector being network-based (AV:N), no required privileges (PR:N), no user interaction (UI:N), and high impact on confidentiality, integrity, and availability (VC:H, VI:H, VA:H). The scope is unchanged, indicating the vulnerability affects the component itself without extending beyond it. No known exploits have been reported in the wild yet, but the ease of exploitation and critical impact make it a prime target for attackers. The lack of authentication on an administrative interface can lead to unauthorized system control, data breaches, and potential disruption of services. DreamMaker is used in various enterprise environments, making this vulnerability particularly concerning for organizations relying on it for critical business functions.

For European organizations, the impact of CVE-2026-24728 could be severe. Unauthorized access to administrative functions can lead to full system compromise, data theft, manipulation, or destruction, and disruption of business operations. Industries such as manufacturing, telecommunications, and critical infrastructure that may use DreamMaker for automation or management tasks are at heightened risk. The vulnerability could facilitate lateral movement within networks, enabling attackers to escalate privileges and access sensitive data or control other systems. Given the high CVSS score and no requirement for authentication or user interaction, exploitation can be automated and widespread. This poses a significant threat to confidentiality, integrity, and availability of affected systems, potentially leading to regulatory non-compliance under GDPR if personal data is compromised. The absence of known exploits currently offers a window for proactive defense, but the critical nature demands immediate attention to prevent future attacks.

1. Immediate application of patches or updates from Internet Information Co., Ltd once they are released is paramount. 2. Until patches are available, restrict network access to the /servlet/baServer3 endpoint using firewalls or network segmentation to limit exposure only to trusted administrators. 3. Implement strict access control lists (ACLs) and monitor logs for any unauthorized access attempts to the vulnerable endpoint. 4. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the /servlet/baServer3 path. 5. Conduct thorough audits of DreamMaker configurations to ensure no other endpoints lack authentication. 6. Increase network monitoring and anomaly detection to identify potential exploitation attempts early. 7. Educate IT and security teams about this vulnerability to ensure rapid response and incident handling. 8. Consider deploying intrusion detection/prevention systems (IDS/IPS) tuned to detect exploitation patterns related to this vulnerability. 9. Maintain an inventory of all DreamMaker instances across the organization to ensure no system is overlooked. 10. Engage with the vendor for guidance and support on mitigation and patch timelines.
