CVE-2008-2268 in Mjguest
Summary
by MITRE
Open redirect vulnerability in interface/redirect.htm.php in Mjguest 6.7 GT Rev.01 allows user-assisted remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the goto parameter in a redirect action to mjguest.php. NOTE: this is user-assisted because there is a delay and a notification before redirection occurs.

The CVE-2008-2268 vulnerability represents a classic open redirect flaw that exists within the Mjguest 6.7 GT Rev.01 web application framework. This security weakness is specifically located in the interface/redirect.htm.php file and manifests when the application processes a redirect action through mjguest.php with a goto parameter. The vulnerability operates by accepting user-supplied URLs in the redirect parameter without proper validation or sanitization, allowing malicious actors to manipulate the redirection behavior. This type of vulnerability falls under CWE-601, which specifically addresses open redirect vulnerabilities where applications redirect users to unvalidated external URLs. The flaw demonstrates a fundamental failure in input validation and output encoding practices that are critical for web application security.
The technical implementation of this vulnerability creates a dangerous scenario where attackers can craft malicious URLs that appear legitimate to end users. When a victim clicks on a specially crafted link containing the malicious goto parameter, the application processes the request and redirects the user to an attacker-controlled website. The user-assisted nature of this vulnerability means that users must actively click on the malicious link, but the delay and notification mechanism before redirection provides attackers with an opportunity to execute social engineering campaigns. The vulnerability operates at the application layer and requires no special privileges or authentication to exploit, making it particularly dangerous for phishing campaigns. This weakness directly maps to ATT&CK technique T1566.001, which covers phishing through spearphishing attachments, as the open redirect can be used to deliver malicious payloads through deceptive redirections.
The operational impact of CVE-2008-2268 extends beyond simple redirection to encompass broader security implications for user trust and application integrity. Attackers can leverage this vulnerability to create convincing phishing pages that appear to originate from legitimate sources within the target domain, thereby bypassing user suspicion and security awareness. The delay and notification feature that accompanies the redirection provides attackers with a window to observe user behavior and potentially adjust their attack vectors. Organizations using Mjguest 6.7 GT Rev.01 become vulnerable to credential theft, malware distribution, and reputation damage as users are unknowingly redirected to malicious sites. The vulnerability also enables attackers to exploit the trust relationship between users and the application, potentially leading to more sophisticated attacks that build upon the initial redirection. This type of vulnerability can also be chained with other security flaws to create more complex attack scenarios, making it a particularly dangerous weakness in web application security.
Mitigation strategies for CVE-2008-2268 should focus on implementing strict input validation and URL sanitization measures within the application's redirect functionality. The most effective approach involves validating the destination URL against a predefined whitelist of trusted domains or implementing a secure redirect mechanism that does not accept external URLs from user input. Organizations should also consider implementing proper logging and monitoring to detect suspicious redirect patterns and user behavior that might indicate exploitation attempts. Security patches should be applied immediately to update the application to a version that addresses this vulnerability, as the flaw exists in a specific release version that has been identified as vulnerable. The implementation of Content Security Policy headers and proper HTTP response handling can further reduce the risk of exploitation. Additionally, user education and awareness programs should emphasize the importance of verifying URLs before clicking on links, particularly in email communications or suspicious web interactions that might lead to phishing attacks. Regular security assessments and penetration testing should be conducted to identify similar vulnerabilities in other application components that might present analogous security risks.
