CVE-2026-29597 DDSN Interactive CVE debrief

CVE-2026-29597 is an improper access control vulnerability in DDSN Interactive cm3 Acora CMS version 10.7.1. An editor-privileged user can access sensitive configuration files by force browsing the '/Admin/file_manager/file_details.asp' endpoint and manipulating the 'file' parameter. This can lead to full administrative access to the CMS, unauthorized access to email services, compromise of backend databases, lateral movement within the network, and long-term persistence by an attacker. The vulnerability poses a critical risk of account takeover, privilege escalation, and systemic compromise of the affected application and its associated infrastructure. Defenders should prioritize patching and implement compensating controls.

Who should care

System administrators and security teams responsible for DDSN Interactive cm3 Acora CMS installations should prioritize patching this vulnerability to prevent potential exploitation. Affected operators and platforms should review configurations, monitor for suspicious activity, and ensure proper security controls are in place. Vulnerability management and security teams should track exceptions, retest remediated assets, and verify evidence of remediation.

Technical summary

The vulnerability exists in the '/Admin/file_manager/file_details.asp' endpoint of DDSN Interactive cm3 Acora CMS version 10.7.1. An attacker with editor privileges can manipulate the 'file' parameter to access sensitive configuration files, such as 'cm3.xml', which may contain system administrator credentials, SMTP settings, and database credentials. This improper access control allows for full administrative access to the CMS, unauthorized access to email services, compromise of backend databases, lateral movement within the network, and long-term persistence by an attacker. The exposure of this information can lead to account takeover, privilege escalation, and systemic compromise of the affected application and its associated infrastructure.
