A critical remote code execution (RCE) vulnerability, tracked as CVE-2025-0115, has been discovered in the popular ‘QueryMaster Pro’ database management client. The flaw, which has been assigned a CVSS score of 9.8, affects all versions prior to 4.7.2 and could allow unauthenticated attackers to execute arbitrary code on the host system where the client is installed.

The vulnerability originates from an improper input validation weakness within the application’s data import functionality. When a user imports data from a specially crafted CSV or JSON file, a buffer overflow can be triggered, allowing the attacker to overwrite memory and execute malicious code with the same privileges as the user running the application.

Understanding the Vulnerability and Impact

According to the official advisory released by the software vendor, the flaw resides specifically in the parser responsible for handling file metadata. An attacker can create a malicious data file and convince a user—such as a database administrator or developer—to import it using QueryMaster Pro. Upon parsing the file’s header, the application fails to correctly handle an overly long string value, leading to the buffer overflow. This means the attack vector is as simple as tricking a user into opening a file.

The impact is severe. A successful exploit grants the attacker full control over the victim’s workstation. From there, they could potentially steal database credentials stored by the client, access sensitive company data, pivot to other systems on the internal network, or deploy ransomware. Given that this tool is commonly used by personnel with privileged access, the potential for widespread damage is significant.

Mitigation and Recommendations

The vendor has released QueryMaster Pro version 4.7.2, which completely patches this vulnerability. All users are strongly urged to update their installations immediately. The patched version introduces proper bounds checking in the data import module, preventing the overflow from occurring.

For organizations unable to update immediately, the primary mitigation is to enforce strict policies against importing data from untrusted or unknown sources. Administrators should also consider using application control solutions to restrict the execution of unauthorized code. It is critical for all security teams to identify instances of the vulnerable software within their environments and prioritize patching to prevent exploitation.
