Overview
CVE-2025-61690 is a critical vulnerability that affects KV STUDIO versions 12.23 and prior. It involves a buffer underflow scenario which, if exploited, may allow arbitrary code execution on the affected product. This vulnerability is of significant concern as it could potentially lead to system compromise or data leakage.

KV STUDIO | 12.23 and prior
How the Exploit Works
The vulnerability stems from a buffer underflow issue within KV STUDIO. If a specially crafted file is used with the product, it can trigger the underflow, which in turn allows the attacker to execute arbitrary code. This code execution happens within the context of the application and can lead to complete system compromise or data leakage.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited. This pseudocode represents a specially crafted malicious payload that triggers the buffer underflow:
# Open KV STUDIO file
file = open("vulnerable.kv", "w")
# Create buffer underflow payload
payload = "A" * 5000 # Adjust this value based on the buffer size
# Write the payload to the file
file.write(payload)
# Close the file
file.close()This code works by creating a file that KV STUDIO would read. The file contains a payload that is larger than the expected buffer, thereby causing an underflow. This is a simplified representation and actual exploit may involve more complex manipulations.
Mitigation Guidance
Users are recommended to apply the vendor patch to fix this vulnerability. In cases where immediate patching is impossible, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be implemented as a temporary mitigation measure. These systems can be configured to detect and block attempts to exploit this vulnerability.
