CVE-2007-1989 in DotClear
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in DotClear before 1.2.6 allow remote attackers to inject arbitrary web script or HTML via the (1) post_id parameter to ecrire/trackback.php or the (2) tool_url parameter to tools/thememng/index.php. NOTE: some of these details are obtained from third party information.

The vulnerability described in CVE-2007-1989 represents a critical cross-site scripting flaw affecting DotClear versions prior to 1.2.6. This vulnerability exposes the blogging platform to remote code execution risks through malicious script injection, potentially allowing attackers to compromise user sessions and manipulate content. The issue manifests in two distinct attack vectors within the application's core functionality, demonstrating the widespread nature of the XSS vulnerability across different modules.
The technical exploitation occurs through manipulation of specific HTTP parameters within the application's URL structure. Attackers can inject malicious scripts by targeting the post_id parameter in the ecrire/trackback.php endpoint or the tool_url parameter in tools/thememng/index.php. These parameters are processed without proper input validation or output encoding, creating opportunities for attackers to execute arbitrary JavaScript code within the context of other users' browsers. The vulnerability aligns with CWE-79 which specifically addresses cross-site scripting flaws in web applications, where untrusted data is improperly handled and executed within the browser environment.
The operational impact of this vulnerability extends beyond simple script injection, as it can enable attackers to perform session hijacking, steal user credentials, manipulate content, or redirect users to malicious websites. The affected endpoints represent critical administrative and content management functions within the DotClear platform, making the potential damage significant for organizations relying on this blogging system. Users who visit compromised pages or interact with maliciously crafted trackback links could unknowingly execute attacker-controlled code, leading to complete browser compromise and potential lateral movement within network environments.
Security professionals should implement immediate mitigations including input validation and output encoding for all user-supplied parameters, particularly those used in URL routing and content processing. The recommended solution involves upgrading to DotClear version 1.2.6 or later, which includes proper sanitization of input parameters and enhanced security controls. Organizations should also consider implementing web application firewalls to detect and block malicious script injection attempts, while conducting thorough security testing to identify similar vulnerabilities in other web applications. This vulnerability demonstrates the importance of maintaining up-to-date software versions and implementing proper security controls as outlined in the ATT&CK framework's web application security categories, particularly focusing on the execution of malicious code through web interfaces.
