The vulnerability identified as CVE-2007-5295 represents a critical cross-site scripting flaw affecting two popular wiki platforms, Wikepage Opus 13 2007.2 and TipiWiki 2. This vulnerability resides within the index.php script and demonstrates a classic input validation weakness that allows malicious actors to execute arbitrary web scripts in the context of affected users' browsers. The flaw specifically impacts the PageContent and PageName parameters, which are commonly used for content management and page identification within wiki systems. These parameters serve as entry points for attackers to inject malicious code that can persist and be executed whenever legitimate users access the affected pages.
The technical implementation of this vulnerability stems from insufficient input sanitization and output encoding mechanisms within the wiki applications. When user-supplied data is directly incorporated into web page responses without proper validation or sanitization, it creates an environment where attacker-controlled content can be interpreted as executable script rather than plain text. The CWE-79 classification applies here as this represents a failure to sanitize user input before incorporating it into dynamically generated web content. This vulnerability operates under the principle that user input should never be trusted and must be properly escaped or validated before being rendered in web contexts. The attack vector is particularly dangerous because it requires no authentication and can be executed through simple web requests that manipulate the PageContent and PageName parameters.
The operational impact of CVE-2007-5295 extends beyond simple script execution, as it can enable sophisticated attacks including session hijacking, credential theft, and redirection to malicious sites. Attackers can craft payloads that steal cookies, modify page content, or redirect users to phishing sites that appear legitimate. The persistence of these vulnerabilities means that once exploited, malicious scripts can affect all users who view the compromised pages until the underlying flaw is patched. This makes the vulnerability particularly dangerous in collaborative environments where multiple users frequently access and contribute to wiki content. The ATT&CK framework categorizes this under T1566 - Phishing and T1059 - Command and Scripting Interpreter, as the vulnerability enables both social engineering attacks through crafted content and direct execution of malicious code within user browsers. Organizations using these wiki platforms face significant risks including data exfiltration, unauthorized access to sensitive information, and potential compromise of entire user sessions.
Mitigation strategies for CVE-2007-5295 require immediate implementation of input validation and output encoding measures. Organizations should implement strict sanitization of all user inputs, particularly those used in dynamic page generation, and ensure proper HTML escaping before rendering content. The most effective long-term solution involves upgrading to patched versions of the affected software, as these vulnerabilities were addressed in subsequent releases through improved input handling mechanisms. Security teams should also implement web application firewalls to detect and block suspicious parameter values, and conduct regular security assessments to identify similar vulnerabilities in other web applications. Additionally, user education regarding the risks of clicking on untrusted links or content within wiki environments can help reduce successful exploitation attempts. The vulnerability highlights the critical importance of secure coding practices and input validation in web applications, serving as a reminder that even seemingly simple parameters can represent significant security risks when not properly handled.
