CVE-2025-1421 in Konsola MDM
Summary
by MITRE • 05/21/2025
Data provided in a request performed to the server while activating a new device are put in a database. Other high privileged users might download this data as a CSV file and corrupt their PC by opening it in a tool such as Microsoft Excel. The attacker could gain remote access to the user's PC.
This issue has been fixed in 2.17.5 version of Konsola Proget (server part of the MDM suite).

This vulnerability exists within the Konsola Proget MDM suite where device activation requests contain sensitive data that gets stored in a database. The flaw arises from insufficient input validation and sanitization of data received during device provisioning processes. When high-privileged users download this data as a CSV file for administrative purposes, the maliciously crafted data can exploit vulnerabilities in spreadsheet applications like Microsoft Excel. This represents a classic server-side data handling flaw that enables privilege escalation through malicious data injection. The vulnerability directly relates to CWE-20 Improper Input Validation and CWE-1236 Improper Neutralization of Special Elements used in a CSV File, where user-supplied data is not properly sanitized before being exported to potentially vulnerable client-side applications. The attack vector leverages the trust relationship between the MDM server and administrative users who routinely process CSV data using Microsoft Office applications. According to ATT&CK framework, this maps to T1059.001 Command and Scripting Interpreter: PowerShell and T1078 Valid Accounts, as attackers could potentially use this vulnerability to gain initial access through compromised administrative credentials and then execute malicious code on target systems. The exploitation chain begins with device activation request manipulation, followed by data export and malicious CSV file opening, ultimately leading to remote code execution on the victim's machine. This vulnerability demonstrates a critical weakness in the MDM security model where administrative data handling processes create attack surfaces for privilege escalation. The issue is particularly concerning because it leverages legitimate administrative workflows to deliver malicious payloads, making detection more difficult. The vulnerability affects the server-side processing components of the MDM suite and represents a significant security gap in the data flow between device provisioning and administrative data handling. The exploitation requires minimal privileges to craft the malicious data but relies on administrative users performing routine CSV processing tasks. The fix implemented in version 2.17.5 addresses the core issue by introducing proper data sanitization and validation mechanisms for all data entering the system during device activation. This remediation ensures that potentially malicious data cannot be stored in a format that would be exploitable when downloaded by privileged users. The security update likely incorporates input filtering, output encoding, and proper CSV formatting controls that prevent the injection of executable content into exported files. Organizations should consider this vulnerability as a potential entry point for advanced persistent threats targeting administrative accounts within MDM environments, particularly in scenarios where multiple administrators process device data through spreadsheet applications. The fix addresses both the immediate threat of remote code execution and the broader security implications of insecure data handling in enterprise mobility management systems.
