CVE-2023-6432 in Online Inventory Manager
Summary
by MITRE • 11/30/2023
A vulnerability has been discovered in BigProf Online Invoicing System 2.6, which does not sufficiently encode user-controlled input, resulting in persistent XSS through /inventory/items_view.php, in the FirstRecord parameter. Exploitation of this vulnerability could allow an attacking user to store dangerous JavaScript payloads on the system that will be triggered when the page loads.

The vulnerability identified as CVE-2023-6432 represents a critical persistent cross-site scripting flaw within the BigProf Online Invoicing System version 2.6. This security weakness resides in the /inventory/items_view.php script where the FirstRecord parameter fails to properly sanitize or encode user-supplied input. The vulnerability stems from inadequate input validation and output encoding mechanisms that allow malicious actors to inject malicious JavaScript code into the application's data handling processes. Such flaws typically arise when developers fail to implement proper security controls during the application's development lifecycle, creating opportunities for attackers to manipulate application behavior through crafted input sequences.
The technical exploitation of this vulnerability occurs through the manipulation of the FirstRecord parameter within the items_view.php endpoint. When an attacker crafts malicious input containing JavaScript payloads and submits it through this parameter, the system fails to properly encode or escape the data before rendering it in the web page context. This allows the injected JavaScript code to persist within the application's database or session storage, executing automatically whenever the affected page loads and processes the malicious input. The vulnerability follows the CWE-79 pattern of cross-site scripting, specifically manifesting as a persistent variant where the malicious code is stored server-side rather than being reflected in the request. This persistence characteristic makes the vulnerability particularly dangerous as it can affect multiple users without requiring repeated exploitation attempts.
The operational impact of CVE-2023-6432 extends beyond simple data theft or session hijacking, as it provides attackers with a foothold for more sophisticated attacks within the application environment. Successful exploitation could enable attackers to execute arbitrary JavaScript code in the context of other users' browsers, potentially leading to credential theft, data exfiltration, or privilege escalation within the invoicing system. The vulnerability may also facilitate further attacks through techniques such as clickjacking, where malicious code could manipulate user interfaces to deceive victims into performing unintended actions. Organizations using this invoicing system face significant risks including unauthorized access to financial data, potential regulatory compliance violations, and reputational damage from security breaches.
Mitigation strategies for CVE-2023-6432 should focus on implementing proper input validation and output encoding mechanisms throughout the application's data flow. Developers must ensure that all user-supplied input is properly sanitized before being processed or stored, with particular attention to parameters like FirstRecord that handle dynamic data. The implementation of Content Security Policy headers can provide additional protection against script execution, while regular security audits and penetration testing should be conducted to identify similar vulnerabilities. Organizations should also consider implementing web application firewalls and input validation rules that specifically target XSS attack patterns. According to ATT&CK framework, this vulnerability maps to T1059.007 (Scripting) and T1566.001 (Phishing via Social Media) techniques, highlighting the need for comprehensive security measures. The fix should involve proper parameter validation, output encoding, and input sanitization practices aligned with secure coding standards and OWASP Top Ten recommendations to prevent similar vulnerabilities from emerging in future application versions.
