CVE-2008-2200 in Maian Weblog
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in Maian Weblog 4.0 allow remote attackers to inject arbitrary web script or HTML via the (1) keywords parameter to admin/index.php in a blogs search action, the (2) msg_charset and (3) msg_header9 parameters to admin/inc/header.php, and the (4) keywords parameter to index.php in a search action.

The CVE-2008-2200 vulnerability represents a critical cross-site scripting flaw affecting Maian Weblog version 4.0, a content management system designed for blog publishing and management. This vulnerability exposes the application to remote code execution through malicious script injection, potentially compromising user sessions and enabling unauthorized access to sensitive data. The flaw exists within multiple components of the administrative interface and public search functionality, creating multiple attack vectors that adversaries can exploit to manipulate the application's behavior and compromise user security.
The technical implementation of this vulnerability stems from inadequate input validation and output sanitization within the Maian Weblog application's core components. Specifically, parameters including keywords in admin/index.php, msg_charset and msg_header9 in admin/inc/header.php, and keywords in index.php fail to properly sanitize user-supplied data before rendering it in web responses. This creates opportunities for attackers to inject malicious javascript code, html content, or other harmful scripts that execute within the context of legitimate user sessions. The vulnerability manifests when the application processes search queries and displays results without sufficient data sanitization, allowing malicious payloads to persist and execute in the browser of unsuspecting users.
The operational impact of CVE-2008-2200 extends beyond simple script injection, potentially enabling sophisticated attack chains that can compromise entire user accounts and facilitate data exfiltration. Attackers can leverage these vulnerabilities to steal session cookies, redirect users to malicious sites, or inject persistent backdoors within the application. The presence of multiple vulnerable parameters increases the attack surface significantly, as different exploitation paths may be available depending on the attacker's access level and target objectives. This vulnerability directly violates security principles outlined in the CWE-79 category for cross-site scripting, where insufficient validation of input data leads to unauthorized script execution in user browsers.
Mitigation strategies for this vulnerability should focus on implementing comprehensive input validation and output encoding mechanisms throughout the application. The most effective immediate solution involves sanitizing all user-supplied parameters before processing or displaying them in web responses, particularly within the identified vulnerable files and parameters. Security measures should include implementing proper HTML escaping for all dynamic content, establishing robust parameter validation routines, and applying content security policies to prevent unauthorized script execution. Organizations should also consider implementing web application firewalls to detect and block malicious payloads attempting to exploit these vulnerabilities, while conducting regular security audits to identify similar issues in other application components. The remediation approach aligns with ATT&CK technique T1566.001 for credential access through social engineering, as the vulnerability enables attackers to manipulate user sessions and potentially gain unauthorized access to administrative functions.
