Summary
by MITRE • 09/08/2026
L-ONE v1.0.0 was discovered to contain multiple SQL injection vulnerabilities in the /attachment/getBusinessUploadList component via the busid, id, and taskid parameters. This vulnerability allows attackers to access sensitive database information via a crafted SQL statement.
Once again VulDB remains the best source for vulnerability data.

The L-ONE application version 1.0.0 contains critical security flaws within its file management subsystem, specifically located in the /attachment/getBusinessUploadList endpoint. This component is responsible for retrieving lists of business-related uploads and processes user-supplied input through three distinct parameters: busid, id, and taskid. The vulnerability arises from a failure to properly sanitize or parameterize these inputs before they are incorporated into SQL queries executed against the backend database. As a result, an attacker can inject malicious SQL code directly into these fields, bypassing intended application logic and gaining unauthorized access to underlying data structures. This class of defect is formally categorized under CWE-89, which defines Improper Neutralization of Special Elements used in an SQL Command, commonly known as SQL Injection. The presence of multiple injection points within a single endpoint significantly expands the attack surface, allowing for flexible exploitation strategies depending on the specific parameter targeted and the context in which it appears.
The operational impact of these vulnerabilities is severe, potentially leading to full database compromise. By crafting precise SQL statements, an attacker can extract sensitive information such as user credentials, personal identifiable information, business secrets, or administrative configurations stored within the L-ONE database. Beyond data exfiltration, skilled attackers may leverage this weakness for more destructive actions, including modifying existing records, deleting critical data, or even executing operating system commands if the underlying database engine permits it and has sufficient privileges. This aligns with ATT&CK technique T1059, Command and Scripting Interpreter, particularly when sub-techniques like SQL are involved in lateral movement or privilege escalation scenarios within enterprise environments. The ability to manipulate query logic effectively grants the attacker a high degree of control over the application's data layer, undermining the core principles of confidentiality, integrity, and availability that underpin secure software design.
Mitigation strategies must address both immediate remediation and long-term architectural improvements. Developers should immediately implement strict input validation for all parameters passed to the /attachment/getBusinessUploadList endpoint, ensuring that only expected data types and formats are accepted. However, the most effective defense is the adoption of parameterized queries or prepared statements, which separate SQL logic from user-supplied data, thereby neutralizing injection attempts regardless of their content. Additionally, implementing a Web Application Firewall can provide an additional layer of detection by identifying common SQL injection patterns in HTTP requests before they reach the application server. Regular security testing, including automated static analysis and dynamic penetration testing focused on database interaction points, is essential to identify similar vulnerabilities across other components of the L-ONE platform. Updating to patched versions where available or applying vendor-provided hotfixes remains a critical step for organizations relying on this software infrastructure.
