The vulnerability identified as CVE-2008-2047 represents a critical SQL injection flaw within the Angelo-Emlak 1.0 web application, specifically affecting two key endpoints in the hpz directory. This vulnerability resides in the application's handling of user input through the id parameter, which is processed in both profil.asp and prodetail.asp scripts. The flaw stems from inadequate input validation and sanitization practices, allowing malicious actors to inject arbitrary SQL commands into the database query execution flow. The vulnerability is classified under CWE-89 which specifically addresses SQL injection weaknesses, where user-supplied data is directly incorporated into SQL commands without proper escaping or parameterization mechanisms. This particular instance demonstrates a classic lack of input sanitization that has been a persistent issue in web application security for decades, with the vulnerability being particularly dangerous due to its remote exploitability.
The technical exploitation of this vulnerability occurs when an attacker crafts malicious SQL payloads and injects them through the id parameter in the affected URLs. The application fails to properly validate or escape the input before incorporating it into database queries, creating a direct path for attackers to manipulate the underlying database operations. When the application processes these malicious inputs, the SQL commands are executed with the privileges of the database user account, potentially allowing for data extraction, modification, or even complete database compromise. The attack surface is specifically limited to the two mentioned scripts but the impact is significant as these endpoints likely serve user profiles and product details, making them valuable targets for information gathering and system compromise. The vulnerability's remote nature means that attackers do not require physical access to the system, and can exploit it from anywhere on the internet, making it particularly dangerous for publicly accessible web applications.
The operational impact of this vulnerability extends beyond simple data theft, as it can enable attackers to gain unauthorized access to sensitive user information, manipulate database content, and potentially escalate privileges within the application's database environment. This type of vulnerability directly violates security principles outlined in the OWASP Top Ten, specifically addressing injection flaws that rank among the most critical web application security risks. The consequences for the affected organization include potential data breaches, regulatory compliance violations, and significant reputational damage. From an attacker's perspective, this vulnerability provides a pathway to achieve persistent access and can serve as a foothold for further attacks within the network infrastructure. The vulnerability also aligns with ATT&CK technique T1071.004 which covers application layer protocol manipulation, and T1190 which addresses exploit public-facing application vulnerabilities, making it a clear target for automated exploitation tools and manual attack campaigns.
Mitigation strategies for this vulnerability must focus on implementing proper input validation and parameterized queries throughout the application codebase. The most effective remediation involves replacing direct string concatenation with prepared statements or parameterized queries that separate SQL command structure from user data. Organizations should implement comprehensive input sanitization routines that filter or escape special characters that could be used in SQL injection attacks. Additionally, the principle of least privilege should be enforced by ensuring database accounts used by the web application have minimal required permissions, preventing attackers from escalating privileges even if successful in initial exploitation attempts. Regular security testing including automated vulnerability scanning and manual penetration testing should be implemented to identify similar flaws in other application components. The remediation process should also include implementing web application firewalls and input validation controls at the network perimeter to detect and block suspicious SQL injection attempts. Security awareness training for developers should emphasize secure coding practices and the importance of never trusting user input when constructing database queries. The vulnerability demonstrates the critical importance of following secure coding standards and the potential consequences of neglecting fundamental security controls in web application development processes.
