CVE-2017-6907 in Open.GL
Summary
by MITRE
An issue was discovered in Open.GL before 2017-03-13. The vulnerability exists due to insufficient filtration of user-supplied data (content) passed to the "Open.GL-master/index.php" URL. An attacker could execute arbitrary HTML and script code in a browser in the context of the vulnerable website.

The vulnerability identified as CVE-2017-6907 represents a classic cross-site scripting flaw within the Open.GL web application framework. This security weakness emerged in versions prior to the 2017-03-13 release, indicating a window of exposure where the application failed to properly validate and sanitize user input before processing it within the web interface. The specific point of failure occurred in the index.php file of the Open.GL-master directory, where user-supplied content was being directly incorporated into the application's response without adequate sanitization measures.
The technical nature of this vulnerability aligns with CWE-79, which describes cross-site scripting flaws that occur when an application includes untrusted data in a new web page without proper validation or escaping, or when it reuses a buffer without resetting its contents. The flaw stems from insufficient filtration mechanisms that should have been implemented to prevent malicious content from being executed within the browser context of legitimate users. When users visited the vulnerable page, any malicious HTML or script code submitted by an attacker would be executed in the context of the vulnerable website, effectively allowing for session hijacking, defacement, or further exploitation of the affected system.
The operational impact of this vulnerability extends beyond simple data theft or display manipulation. Attackers could leverage this flaw to steal user sessions, redirect victims to malicious sites, inject malicious advertisements, or perform actions on behalf of authenticated users. The vulnerability particularly affects web applications that dynamically incorporate user-generated content without proper sanitization, making it a significant concern for content management systems, forums, and any platform accepting user input for display. The risk is amplified because the attack requires no special privileges or complex exploitation techniques, making it accessible to a wide range of threat actors.
Mitigation strategies for CVE-2017-6907 should focus on implementing robust input validation and output encoding mechanisms. Organizations should ensure that all user-supplied data is properly sanitized before being processed or displayed, utilizing established libraries and frameworks that provide built-in protection against XSS attacks. The fix involves updating the Open.GL application to version 2017-03-13 or later, which would incorporate proper input validation measures and output encoding. Additionally, implementing Content Security Policy headers, using proper HTML escaping for dynamic content, and conducting regular security code reviews can help prevent similar vulnerabilities from emerging in the future. This vulnerability demonstrates the critical importance of following secure coding practices and adhering to established security frameworks such as those outlined in the OWASP Top Ten project, which consistently ranks XSS as one of the most prevalent web application security risks.
