Overview
The cybersecurity industry is again faced with a high-risk vulnerability in a widely used open-source application, WebERP v4.15.2. This vulnerability, identified as CVE-2025-46052, allows cyber attackers to execute arbitrary SQL commands and extract sensitive data by exploiting an error-based SQL Injection (SQLi) in the DEL form field. This vulnerability is significant because of the high severity score (9.8/10) based on the Common Vulnerability Scoring System (CVSS), indicating a potential for serious system compromise or data leakage.

How the Exploit Works
The vulnerability lies in the DEL form field in a POST request to /StockCounts.php. A cyber attacker can inject a crafted payload into this field, which is not properly sanitized by the application. This allows the attacker to manipulate SQL statements executed by the application, leading to arbitrary SQL command execution. This type of vulnerability is known as an SQL Injection (SQLi) and is a common attack vector for cyber attackers.
Conceptual Example Code
Here’s a
conceptual
example of how the vulnerability might be exploited, using an HTTP POST request:
POST /StockCounts.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
DEL=' OR '1'='1'; DROP TABLE members; --In this example, the malicious payload `OR ‘1’=’1′; DROP TABLE members; –` is injected to the `DEL` form field, which forces the SQL statement to always return true and subsequently drops the ‘members’ table from the database.
Mitigation
The primary solution to this vulnerability is to apply the vendor patch. In the absence of a patch, implementing a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can help to mitigate the risk temporarily by detecting and blocking such malicious payloads. It’s also essential to sanitize all user inputs within the application and use prepared statements or parameterized queries to prevent SQL injection.
