The CVE-2015-7569 vulnerability represents a critical SQL injection flaw within the Yeager Content Management System version 1.2.1, specifically affecting the yeager/y.php endpoint with the tab_USERLIST functionality. This vulnerability resides in the parameter handling mechanism for pagedir_orderby, which fails to properly sanitize user input before incorporating it into database queries. The flaw enables local attackers who already have system access to escalate their privileges and execute arbitrary SQL commands against the underlying database. This type of vulnerability falls under the CWE-89 category of SQL Injection, which is classified as a high-risk vulnerability due to its potential for data compromise and system takeover.
The technical exploitation of this vulnerability occurs through the manipulation of the pagedir_orderby parameter within the yeager/y.php/tab_USERLIST endpoint. When a local user submits malicious input through this parameter, the application fails to implement proper input validation or parameterized queries, allowing the attacker to inject SQL code that gets executed within the database context. The vulnerability is particularly concerning because it requires only local system access to exploit, meaning that an attacker who has already compromised a system or gained user-level privileges can leverage this flaw to gain deeper access to the database layer. This represents a classic case of insufficient input sanitization, where user-provided data flows directly into SQL execution contexts without proper filtering or escaping mechanisms.
The operational impact of CVE-2015-7569 extends beyond simple data theft to encompass complete system compromise and potential data destruction. Local users who exploit this vulnerability can execute commands that may allow them to extract sensitive information from the database, modify or delete critical records, and potentially escalate privileges to administrative levels within the database system. The vulnerability's presence in a content management system makes it particularly dangerous as it could provide access to user credentials, content management data, and potentially other system information. This type of vulnerability aligns with ATT&CK technique T1078.004 which covers legitimate credentials and T1046 which involves network service scanning, as exploitation could lead to further reconnaissance and lateral movement within the network.
Mitigation strategies for CVE-2015-7569 must address both the immediate vulnerability and broader security posture of the affected system. The primary remediation involves implementing proper input validation and parameterized queries for all database interactions, particularly within the yeager/y.php endpoint. Organizations should ensure that all user-provided input is sanitized and validated before being processed, with the implementation of prepared statements or parameterized queries to prevent SQL injection attacks. Additionally, system administrators should implement the principle of least privilege, ensuring that local user accounts have minimal necessary permissions within the database environment. The vulnerability also highlights the importance of regular security assessments and vulnerability scanning, as this flaw could have been identified through automated security tools. Organizations should also consider implementing database activity monitoring and intrusion detection systems to detect and respond to potential exploitation attempts. The remediation process should include updating to a patched version of Yeager CMS if available, or implementing application-level controls to prevent the specific parameter from being processed in an unsafe manner.
