The Devome GRR v4.5.0 web application presents a critical security vulnerability through multiple authenticated SQL injection flaws located within the include/session.inc.php file. This vulnerability specifically manifests when processing the referer and user-agent HTTP headers, creating an attack surface that allows authenticated users to manipulate database queries through malicious input. The flaw stems from insufficient input validation and sanitization of these HTTP headers, which are typically used for tracking and logging purposes but become dangerous when directly incorporated into database queries without proper escaping or parameterization. The vulnerability affects the application's session management functionality where these headers are processed during user authentication and session establishment.
The technical exploitation of this vulnerability requires an authenticated user context, meaning attackers must first obtain valid credentials to the application before attempting to leverage the SQL injection. However, the authenticated nature of the vulnerability does not mitigate its severity as it still provides attackers with direct access to the underlying database infrastructure. When an attacker crafts malicious referer or user-agent values containing SQL payload strings, the application's flawed input handling allows these payloads to be executed within the database context. This creates potential for data exfiltration, unauthorized data modification, and privilege escalation within the database environment. The vulnerability aligns with CWE-89 which specifically addresses SQL injection flaws where untrusted data is incorporated into SQL commands without proper sanitization.
The operational impact of this vulnerability extends beyond simple data compromise as it enables attackers to potentially extract sensitive user information, including authentication credentials stored in the database, personal user data, and application configuration details. The attack surface is particularly concerning because HTTP headers like referer and user-agent are commonly logged and processed by web applications without extensive validation, making this a common vector for exploitation in web applications. Successful exploitation could result in full database compromise, allowing attackers to create new user accounts with elevated privileges, modify existing user permissions, or even delete critical application data. This vulnerability directly impacts the confidentiality, integrity, and availability of the application's data storage layer.
Organizations using Devome GRR v4.5.0 should prioritize immediate remediation through patching the application to version 4.5.1 or later which addresses these SQL injection vulnerabilities. The recommended mitigation strategy includes implementing proper input validation and sanitization for all HTTP headers before database processing, utilizing parameterized queries or prepared statements to prevent SQL injection, and implementing proper authentication controls with session management. Additionally, network segmentation and monitoring should be enhanced to detect suspicious header values that may indicate exploitation attempts. This vulnerability demonstrates the importance of input validation across all application components and aligns with ATT&CK technique T1071.004 which covers application layer protocol manipulation. Organizations should also consider implementing web application firewalls and database activity monitoring to detect and prevent exploitation attempts. The vulnerability highlights the critical need for security testing during application development phases and regular security audits to identify similar flaws in authentication and session management components.
