CVE-2006-3184 in ASP Stats Generator
Summary
by MITRE
Direct static code injection vulnerability in ASP Stats Generator before 2.1.2 allows remote authenticated attackers to execute arbitrary ASP code via the strAsgSknPageBgColour parameter to settings_skin.asp, which is stored in inc_skin_file.asp.

The CVE-2006-3184 vulnerability represents a critical direct static code injection flaw within the ASP Stats Generator application, specifically affecting versions prior to 2.1.2. This vulnerability resides in the application's handling of user-supplied input within the settings_skin.asp file, where the strAsgSknPageBgColour parameter is processed without adequate sanitization or validation. The flaw enables authenticated attackers to inject arbitrary ASP code into the application's configuration, creating a persistent backdoor that can be executed within the application's runtime environment.
The technical exploitation of this vulnerability occurs through a classic code injection vector where attacker-controlled input flows directly into the application's dynamic code generation process. When the strAsgSknPageBgColour parameter is submitted to settings_skin.asp, the application fails to properly validate or sanitize this input before storing it in the inc_skin_file.asp component. This stored value is then executed as ASP code, allowing attackers to perform arbitrary operations on the affected system. The vulnerability is classified as a direct static code injection because the malicious code is directly embedded into the application's execution flow rather than being indirectly executed through other mechanisms.
The operational impact of this vulnerability extends beyond simple code execution, as it provides attackers with persistent access to the target system through the stored ASP code injection. An authenticated attacker with access to the application's administrative interface can leverage this vulnerability to execute commands, escalate privileges, and potentially compromise the entire web server hosting the application. The vulnerability is particularly dangerous because it allows attackers to maintain access even after the initial exploitation attempt, as the injected code remains stored in the application's configuration files and continues to execute with each page load.
From a cybersecurity perspective, this vulnerability aligns with CWE-94, which describes the weakness of "Improper Control of Generation of Code ('Code Injection')" and relates to the broader category of injection flaws that have been consistently ranked among the top security vulnerabilities in industry standards such as the OWASP Top Ten. The attack pattern follows typical ATT&CK techniques for code injection and privilege escalation, where adversaries leverage application-level vulnerabilities to establish persistent access and execute malicious code within the target environment. Organizations should implement input validation, output encoding, and proper access controls to prevent such vulnerabilities from being exploited, while also ensuring that all web applications are regularly updated to address known security flaws.
Mitigation strategies for CVE-2006-3184 should focus on immediate patching of the ASP Stats Generator application to version 2.1.2 or later, which contains the necessary fixes to address the code injection vulnerability. Additionally, organizations should implement robust input validation mechanisms that sanitize all user-supplied parameters before processing, employ proper output encoding to prevent malicious code from being executed, and establish network segmentation to limit the potential impact of successful exploitation attempts. Regular security audits and penetration testing should be conducted to identify similar vulnerabilities within the application's codebase, while access controls should be strictly enforced to minimize the risk of unauthorized administrative access that could facilitate exploitation of this vulnerability.
