The vulnerability CVE-2018-10073 represents a cross-site scripting flaw discovered in joyplus-cms version 1.6.0 within the manager/admin_vod.php component. This issue arises from insufficient input validation and output sanitization mechanisms that fail to properly handle user-supplied data. The vulnerability specifically manifests through the keyword parameter, which serves as an entry point for malicious actors to inject harmful scripts into the application's response. The flaw enables attackers to execute arbitrary JavaScript code within the context of other users' browsers, potentially compromising the integrity of the web application and the confidentiality of user data.
This vulnerability falls under the CWE-79 category of Cross-Site Scripting, which is classified as a critical security weakness in web applications. The technical implementation of this flaw demonstrates poor input validation practices where the application directly incorporates user-provided parameters into dynamic web content without appropriate sanitization or encoding. The keyword parameter in manager/admin_vod.php likely processes search queries or content filtering operations, making it a prime target for exploitation. When an attacker submits malicious script code through this parameter, the application fails to properly escape or encode the output, allowing the injected code to execute in the victim's browser environment.
The operational impact of CVE-2018-10073 extends beyond simple script execution, as it can facilitate more sophisticated attacks within the context of the web application. Attackers can leverage this vulnerability to steal session cookies, redirect users to malicious sites, perform unauthorized actions on behalf of victims, or even establish persistent backdoors within the CMS environment. The vulnerability affects the administrator interface, making it particularly dangerous as it could allow attackers to gain elevated privileges and compromise the entire content management system. This exposure creates a significant risk for organizations relying on joyplus-cms for content management, as successful exploitation could lead to complete system compromise and data breaches.
Mitigation strategies for CVE-2018-10073 should focus on implementing robust input validation and output encoding mechanisms throughout the application. The most effective approach involves sanitizing all user inputs, particularly parameters like keyword, through proper encoding techniques such as HTML entity encoding before rendering them in web pages. Organizations should also implement Content Security Policy headers to limit script execution and prevent unauthorized code injection. The recommended fix includes updating joyplus-cms to version 1.6.1 or later, which contains patches addressing this vulnerability. Additionally, implementing proper input validation using allowlists for acceptable characters and lengths, combined with regular security testing and code reviews, will help prevent similar vulnerabilities from emerging in future releases. The ATT&CK framework categorizes this vulnerability under T1213 - Data from Information Repositories, as it provides unauthorized access to stored data within the CMS system through client-side exploitation techniques.
