CVE-2006-3002 in Easy Ad-Manager
Summary
by MITRE
Cross-site scripting (XSS) vulnerability in details.php in Easy Ad-Manager allows remote attackers to inject arbitrary web script or HTML via the mbid parameter, which is reflected in an error message. NOTE: on 20060829, the vendor notified CVE that this issue has been fixed.

The vulnerability described in CVE-2006-3002 represents a classic cross-site scripting flaw within the Easy Ad-Manager application's details.php component. This security weakness specifically manifests when the application fails to properly sanitize user input passed through the mbid parameter, creating an avenue for malicious actors to execute arbitrary web scripts or HTML code within the context of other users' browsers. The vulnerability occurs during error handling processes where the application reflects the unsanitized mbid parameter value directly into error messages displayed to users, thereby enabling attackers to inject malicious payloads that persist and execute when other users encounter these error conditions.
The technical implementation of this XSS vulnerability aligns with CWE-79, which categorizes cross-site scripting as a critical weakness in web applications where untrusted data is improperly incorporated into web pages without proper validation or encoding. This particular flaw operates as a reflected XSS attack since the malicious script is not stored on the server but rather injected through a crafted URL parameter that gets immediately reflected back to the user's browser. The vulnerability's exploitation requires minimal prerequisites, as attackers only need to craft a malicious URL containing the XSS payload within the mbid parameter and convince a victim to click the link, making it particularly dangerous in social engineering scenarios.
From an operational impact perspective, this vulnerability poses significant risks to the confidentiality, integrity, and availability of the affected system's user data and session information. Successful exploitation could allow attackers to steal user session cookies, enabling unauthorized access to user accounts and potentially leading to full system compromise. The reflected nature of the vulnerability means that attackers could craft multiple malicious payloads to target specific user groups or exploit the vulnerability across different user sessions. Additionally, the vulnerability could be leveraged to deface web pages, redirect users to malicious sites, or harvest sensitive information from users interacting with the vulnerable application.
The mitigation strategies for CVE-2006-3002 should focus on implementing robust input validation and output encoding mechanisms within the Easy Ad-Manager application. The primary defense involves sanitizing all user-supplied input parameters, particularly those used in error handling contexts, by implementing proper HTML encoding or escaping before any output occurs. Organizations should also consider implementing Content Security Policy (CSP) headers to limit the execution of unauthorized scripts, along with regular security code reviews and input validation testing. This vulnerability demonstrates the importance of following secure coding practices and adhering to OWASP Top Ten security guidelines, particularly the prevention of XSS vulnerabilities through proper input sanitization and output encoding. The remediation process requires immediate patching of the application code to ensure that the mbid parameter is properly validated and sanitized before being incorporated into any user-facing content or error messages, as recommended by the vendor's notification that the issue was resolved in August 2006.
