The vulnerability identified as CVE-2014-2847 represents a critical SQL injection flaw within the CIS Manager Content Management System, specifically affecting the default.asp component. This vulnerability resides in the handling of user-supplied input through the TroncoID parameter, which is processed without adequate sanitization or validation mechanisms. The CIS Manager CMS, commonly deployed for enterprise content management and web application hosting, becomes susceptible to malicious SQL command execution when this parameter is manipulated by remote attackers. The flaw essentially allows an attacker to inject malicious SQL code directly into the database query execution chain, bypassing normal authentication and authorization controls.
The technical implementation of this vulnerability stems from improper input validation practices within the default.asp script, which directly incorporates user-provided TroncoID values into SQL query construction without appropriate parameterization or escaping mechanisms. This primitive approach to database interaction creates an environment where attacker-controlled input can alter the intended structure of SQL statements, potentially leading to unauthorized data access, modification, or deletion. The vulnerability aligns with CWE-89, which specifically addresses SQL injection weaknesses where untrusted data is incorporated into SQL queries without proper sanitization. The attack vector is particularly dangerous as it requires no authentication or privileged access, making it exploitable by any remote attacker who can submit requests to the vulnerable application.
The operational impact of this vulnerability extends beyond simple data theft, encompassing complete database compromise and potential system escalation. Successful exploitation could enable attackers to extract sensitive information including user credentials, personal data, and business-critical documents stored within the CMS database. Additionally, the attacker might modify or delete content, potentially causing service disruption or data corruption that could severely impact business operations. The vulnerability also provides a potential foothold for further attacks within the network infrastructure, as compromised CMS systems often serve as entry points for lateral movement and privilege escalation activities. According to ATT&CK framework, this vulnerability maps to T1190 - Exploit Public-Facing Application, where attackers leverage application weaknesses to gain initial access to target systems.
Mitigation strategies for CVE-2014-2847 should prioritize immediate implementation of proper input validation and parameterized queries to prevent SQL injection attacks. Organizations must ensure that all user-supplied parameters are rigorously sanitized and validated before processing, with particular attention to the TroncoID parameter in this context. The implementation of prepared statements or parameterized queries should replace direct string concatenation approaches in database interactions. Additionally, access controls and input filtering mechanisms should be strengthened to prevent malicious payloads from reaching the database layer. Network segmentation and web application firewalls can provide additional protective layers, while regular security assessments and code reviews should be conducted to identify and remediate similar vulnerabilities. System administrators should also implement proper monitoring and logging of database activities to detect potential exploitation attempts and maintain audit trails for forensic analysis.
