CVE-2013-20006 in Qool
Summary
by MITRE • 03/16/2026
Qool CMS contains multiple persistent cross-site scripting vulnerabilities in several administrative scripts where POST parameters are not properly sanitized before being stored and returned to users. Attackers can inject malicious JavaScript code through parameters like 'title', 'name', 'email', 'username', 'link', and 'task' in endpoints such as addnewtype, addnewdatafield, addmenu, addusergroup, addnewuserfield, adduser, addgeneraldata, and addcontentitem to execute arbitrary scripts in administrator browsers.

Qool CMS suffers from multiple persistent cross-site scripting vulnerabilities that arise from inadequate input sanitization in administrative scripts. These flaws exist in critical endpoints including addnewtype, addnewdatafield, addmenu, addusergroup, addnewuserfield, adduser, addgeneraldata, and addcontentitem where user-supplied data is directly stored without proper validation or encoding. The vulnerability affects POST parameters such as title, name, email, username, link, and task, creating a persistent XSS attack surface that can be exploited by malicious actors to inject malicious JavaScript code into the application's administrative interface.
The technical implementation of this vulnerability stems from a failure to apply proper input validation and output encoding mechanisms within the CMS's administrative functions. When administrators interact with these endpoints, the application stores the unsanitized input directly into the database without adequate sanitization processes. This creates a persistent threat where malicious code injected during the initial submission remains stored and will execute whenever administrative users view the affected content. The vulnerability operates under CWE-79 which specifically addresses cross-site scripting flaws, and the persistent nature of the vulnerability aligns with CWE-116 which deals with improper encoding or escaping of output data.
The operational impact of this vulnerability is significant as it allows attackers to execute arbitrary scripts within the context of administrative sessions, potentially leading to complete system compromise. An attacker who successfully exploits this vulnerability could gain administrative privileges, modify or delete content, access sensitive user data, or establish persistent backdoors within the CMS. The attack vector requires minimal privileges as the exploitation targets administrative functions that are typically accessible to authenticated users with appropriate permissions. This vulnerability directly maps to ATT&CK technique T1059.007 for Command and Scripting Interpreter and T1566.001 for Phishing, as attackers can use the persistent XSS to establish initial access and maintain control over the system.
Mitigation strategies should focus on implementing comprehensive input validation and output encoding mechanisms throughout the application's administrative interface. All user-supplied input must be properly sanitized using established encoding libraries before being stored or rendered in the user interface. The implementation should follow secure coding practices that align with OWASP Top Ten recommendations and specifically address the prevention of XSS vulnerabilities. Additionally, administrators should implement proper access controls and regularly audit administrative functions to identify and remediate similar input validation flaws. The CMS should also implement Content Security Policy headers and utilize proper session management to limit the potential impact of successful exploitation attempts. Regular security testing and code reviews should be conducted to identify and remediate similar vulnerabilities in other administrative endpoints.
