CVE-2015-6944 in JSP
Summary
by MITRE
Cross-site request forgery (CSRF) vulnerability in JSP/MySQL Administrador Web 1 allows remote attackers to hijack the authentication of users for requests that execute arbitrary SQL commands via the cmd parameter to sys/sys/listaBD2.jsp.

The CVE-2015-6944 vulnerability represents a critical cross-site request forgery flaw within the JSP/MySQL Administrador Web 1 application that fundamentally undermines the security of user sessions and administrative operations. This vulnerability exists in the web application's handling of authentication tokens and request validation mechanisms, creating a pathway for malicious actors to exploit legitimate user sessions without proper authorization. The flaw specifically manifests in the sys/sys/listaBD2.jsp endpoint where the cmd parameter is processed without adequate CSRF protection measures, allowing attackers to craft malicious requests that appear to originate from authenticated users.
The technical implementation of this vulnerability stems from the absence of proper anti-CSRF token validation within the web application's request processing pipeline. When users authenticate to the JSP/MySQL Administrador Web 1 interface, their session remains active and valid for subsequent requests. However, the application fails to implement robust CSRF protection mechanisms such as synchronizer tokens or origin validation checks. Attackers can leverage this weakness by constructing specially crafted web requests that include the cmd parameter, which when processed by the vulnerable endpoint, executes arbitrary SQL commands on the underlying database system. This represents a direct violation of the principle of least privilege and demonstrates a failure in implementing proper input validation and request authentication controls.
The operational impact of this vulnerability extends beyond simple data theft or modification, as it enables attackers to execute arbitrary SQL commands that can result in complete database compromise. An attacker with access to a victim's authenticated session can perform operations such as data extraction, data modification, unauthorized user creation, and potentially system escalation. The vulnerability affects the entire administrative interface of the application, making it a high-value target for attackers seeking persistent access to database systems. This flaw particularly threatens organizations using the JSP/MySQL Administrador Web 1 application, as it provides a direct attack vector into their database infrastructure without requiring additional authentication credentials or complex exploitation techniques.
Organizations affected by this vulnerability should implement immediate mitigations including the enforcement of anti-CSRF tokens for all state-changing requests, proper session management controls, and comprehensive input validation. The implementation of the OWASP CSRF Prevention Cheat Sheet recommendations should be prioritized, including the generation of unique tokens for each user session and validation of these tokens on every request. Additionally, the application should be updated to include proper request origin checking and implement the principle of least privilege for database operations. From an ATT&CK framework perspective, this vulnerability maps to TA0001 Initial Access and TA0002 Execution, as attackers can leverage this flaw to establish persistent access and execute malicious commands within the database environment. The vulnerability also aligns with CWE-352, which specifically addresses Cross-Site Request Forgery weaknesses in web applications, emphasizing the critical need for proper session management and request validation controls to prevent unauthorized operations within authenticated web applications.
