CVE-2024-23942 in mbCONNECT24
Summary
by MITRE • 03/18/2025
A local user may find a configuration file on the client workstation with unencrypted sensitive data. This allows an attacker to impersonate the device or prevent the device from accessing the cloud portal which leads to a DoS.

This vulnerability represents a critical configuration flaw in client-side software that exposes sensitive data in plain text within configuration files. The issue stems from inadequate data protection mechanisms during the software installation or runtime processes, where authentication credentials, API keys, or other confidential information are written to disk without proper encryption. According to CWE-312, this constitutes a weakness where sensitive data is stored in cleartext, making it immediately accessible to any local user with file system access. The vulnerability exists at the application level where security controls fail to enforce proper data sanitization and encryption protocols during configuration file generation.
The technical exploitation of this vulnerability allows a local attacker to directly read configuration files containing authentication tokens, device identifiers, or cloud portal credentials. This creates a privilege escalation scenario where an attacker with minimal access to the workstation can gain full device impersonation capabilities. The ATT&CK framework categorizes this under T1566.001 - Phishing: Spearphishing Attachment, as the initial compromise may occur through social engineering or lateral movement, but the exploitation leverages local file system access to extract credentials. The vulnerability's impact extends beyond simple credential theft to include denial of service conditions, as the device may become unable to establish legitimate connections with cloud services when its configuration becomes corrupted or when the attacker manipulates the stored credentials.
The operational consequences of this vulnerability are severe and multifaceted, affecting both device integrity and service availability. Organizations may experience unauthorized device access leading to potential data exfiltration, while legitimate users face service disruption when their devices lose connectivity to cloud management systems. The vulnerability affects device lifecycle management processes, as compromised devices may be unable to receive updates or configuration changes from central management portals. The risk is amplified in enterprise environments where multiple users share workstations or where insufficient access controls exist on client systems, creating an attack surface that can be exploited across various operational domains.
Mitigation strategies should focus on implementing mandatory encryption for all configuration files containing sensitive data, enforcing secure configuration management practices, and establishing robust access controls on client workstations. Organizations should deploy file system monitoring solutions to detect unauthorized access attempts to sensitive configuration files, while implementing principle of least privilege access controls. The solution must address both the immediate vulnerability through patching and the underlying architectural weakness through secure coding practices and configuration management policies. Regular security assessments should verify that no sensitive data is stored in unencrypted formats, and automated tools should be deployed to continuously monitor for such configurations. Additionally, implementing device attestation mechanisms and secure boot processes can prevent unauthorized modifications to configuration files, while network-level controls can detect and block suspicious device access patterns that may indicate credential compromise.
