The CVE-2014-3749 vulnerability represents a critical sql injection flaw in the Construtiva CIS Manager application that exposes organizations to significant remote execution risks. This vulnerability specifically affects the autenticar/lembrarlogin.asp component where the email parameter is improperly validated and processed, creating an exploitable entry point for malicious actors. The flaw resides in the application's authentication mechanism, where user input flows directly into sql query construction without adequate sanitization or parameterization.
This vulnerability falls under the common weakness enumeration CWE-89 which categorizes sql injection as a persistent threat where untrusted data is incorporated into sql commands without proper validation or escaping. The attack vector requires only a remote connection to the application, making it particularly dangerous as it can be exploited from any location without physical access to the network. The email parameter serves as the primary injection point, allowing attackers to manipulate the underlying database queries through crafted input sequences that bypass authentication mechanisms.
The operational impact of this vulnerability extends beyond simple unauthorized access as it enables complete database compromise and potential lateral movement within the affected network. Attackers can leverage this flaw to extract sensitive user credentials, personal information, and potentially gain administrative privileges within the CIS Manager system. The vulnerability's remote exploitability means that threat actors can target the application from external networks without requiring insider knowledge or physical access, making it an attractive target for automated scanning and exploitation campaigns.
Organizations utilizing Construtiva CIS Manager should implement immediate mitigations including input validation for all user-supplied parameters, implementation of prepared statements or parameterized queries, and application-level filtering of sql metacharacters. Network segmentation and intrusion detection systems should monitor for suspicious sql injection patterns targeting the specific endpoint. The vulnerability demonstrates the critical importance of proper input sanitization and the principle of least privilege in database access controls. Security teams should also consider implementing web application firewalls to detect and block malicious sql injection attempts. This vulnerability aligns with ATT&CK technique T1190 which describes exploitation of remote services through sql injection attacks, emphasizing the need for comprehensive application security testing and regular vulnerability assessments to prevent such critical flaws from remaining undetected in production environments.
