Description Summary:
A deserialization of untrusted data vulnerability in Mescius ActiveReports.NET allows remote, unauthenticated attackers to achieve remote code execution.
Executive Summary:
A critical deserialization vulnerability in Mescius ActiveReports.NET poses a severe risk of full system compromise via remote code execution.
Vulnerability Details
CVE-ID: CVE-2025-6810
Affected Software: Mescius ActiveReports.NET
Affected Versions: Mescius ActiveReports.NET: 18.1.1
Vulnerability: This vulnerability involves the insecure deserialization of untrusted data within the ReadValue function, allowing an unauthenticated remote attacker to execute arbitrary code with the privileges of the application process.
Business Impact
Successful exploitation of this flaw allows an attacker to execute arbitrary commands, potentially leading to a complete system takeover. Given the CVSS score of 9.8, this vulnerability is classified as critical, as it requires no user interaction and no authentication, making it highly attractive for automated exploitation.
Remediation Plan
Immediate Action: Update Mescius ActiveReports.NET to the latest available version as specified by the vendor to remove the insecure deserialization capability.
Proactive Monitoring: Monitor server logs for unusual inbound traffic patterns, particularly those originating from untrusted sources targeting the application’s deserialization endpoints.
Compensating Controls: Deploy Web Application Firewall (WAF) rules designed to inspect and filter serialized data streams to prevent the injection of malicious objects.
Exploitation Status
Public Exploit Available: No (unknown)
Analyst Notes: As of July 7, 2025, there is no public information indicating active exploitation or a public proof-of-concept for this vulnerability. The flaw is inherently dangerous due to its lack of authentication requirements and high impact potential.
Analyst Recommendation
The severity of this vulnerability cannot be overstated; the ability for an unauthenticated attacker to execute code remotely necessitates immediate action. Administrators must verify their current version of ActiveReports.NET and apply the vendor-provided patch without delay to prevent potential system compromise.
