The vulnerability identified as CVE-2010-4901 represents a critical cross-site scripting flaw discovered in MySource Matrix version 3.28.3, specifically within the char_map.php component. This vulnerability exposes the application to remote code execution risks where malicious actors can inject arbitrary web scripts or HTML content through carefully crafted input parameters. The flaw manifests in two distinct attack vectors that target the height and width parameters, making it particularly dangerous as it provides multiple entry points for exploitation.
The technical implementation of this vulnerability stems from inadequate input validation and output sanitization within the char_map.php script. When users provide values for the height or width parameters, the application fails to properly sanitize these inputs before incorporating them into the response sent to the victim's browser. This lack of proper input filtering creates an environment where malicious payloads can be executed in the context of the victim's session, potentially leading to session hijacking, data theft, or further compromise of the affected system. The vulnerability aligns with CWE-79 which specifically addresses cross-site scripting flaws resulting from insufficient input validation and output encoding.
From an operational impact perspective, this vulnerability presents significant risks to organizations utilizing MySource Matrix 3.28.3 as their content management platform. Attackers exploiting this flaw could manipulate the application's behavior to redirect users to malicious sites, steal sensitive session cookies, or inject malware directly into user browsers. The remote nature of the attack means that exploitation does not require any local access or privileged credentials, making it particularly dangerous for web applications that serve a large user base. This vulnerability essentially allows attackers to perform actions on behalf of legitimate users, potentially leading to complete compromise of the affected web application and its underlying data.
Security professionals should implement multiple layers of mitigation strategies to address this vulnerability effectively. The primary remediation approach involves updating the MySource Matrix application to a patched version that properly sanitizes input parameters before processing them. Additionally, organizations should deploy web application firewalls that can detect and block malicious payloads targeting these specific parameters. Input validation should be strengthened to reject any non-numeric values for height and width parameters, while output encoding must be implemented to ensure that all dynamic content is properly escaped before being rendered in the browser. This vulnerability demonstrates the importance of following secure coding practices and adheres to ATT&CK technique T1566 which covers the use of web application vulnerabilities for initial access and privilege escalation. Organizations should also consider implementing content security policies to further limit the potential impact of successful XSS attacks and establish comprehensive monitoring to detect any exploitation attempts.
