Overview
The cybersecurity landscape is ever-evolving, and with it comes the persistent threat of new vulnerabilities. One such vulnerability, CVE-2025-27302, has been discovered in CHATLIVE, a popular chat application developed by Claudio Adrian Marrero. This is a serious security issue, as it allows for potential SQL injection attacks, leading to a system compromise or data leakage. Given the widespread use of CHATLIVE, this vulnerability puts numerous systems at risk. This post aims to delve into the details of this vulnerability and provide guidance on how to mitigate the risks associated with it.
Vulnerability Summary

No phone number, email, or personal info required.
Product | Affected Versions
CHATLIVE | n/a through 2.0.1
How the Exploit Works
This vulnerability emerges from improper neutralization of special elements used in an SQL command, commonly known as an SQL injection vulnerability. In other words, the application fails to correctly sanitize user-provided data before passing it to an SQL query. An attacker can exploit this by inserting malicious SQL statements into input fields, for example, in a chat message. These statements could then be executed by the database, leading to unauthorized data access, data manipulation, or even command execution on the underlying system.
Conceptual Example Code
Below is a
conceptual
example of how the vulnerability might be exploited. In this hypothetical scenario, an attacker sends a chat message containing a malicious SQL command, tricking the system into executing it.
POST /send_message HTTP/1.1
Host: chatlive.example.com
Content-Type: application/json
{ "message": "Hello, friend'; DROP TABLE users; --" }In this example, the message includes the string “Hello, friend’; DROP TABLE users; –“. This could cause the system to execute a SQL command that deletes the ‘users’ table from the database, leading to significant data loss.
Mitigation and Recommendations
Given the severity of this vulnerability, it is strongly recommended to apply the vendor patch as soon as it becomes available. However, until such a patch is released, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These systems can detect and block suspicious activity, such as the SQL injection attempts that this vulnerability would allow.
It’s also a good practice to validate and sanitize all inputs and implement parameterized queries or prepared statements to prevent SQL injection attacks. Regularly updating and patching your systems, along with continuous monitoring for any unusual activity, can go a long way in securing your systems against such vulnerabilities.
