CVE-2013-7349 in Gnew
Summary
by MITRE
Multiple SQL injection vulnerabilities in Gnew 2013.1 allow remote attackers to execute arbitrary SQL commands via the (1) news_id parameter to news/send.php, (2) thread_id parameter to posts/edit.php, or (3) user_email parameter to users/password.php or (4) users/register.php. NOTE: these issues were SPLIT from CVE-2013-5640 due to differences in researchers and disclosure dates.

The vulnerability identified as CVE-2013-7349 represents a critical SQL injection flaw affecting the Gnew 2013.1 web application, specifically targeting four distinct entry points that collectively expose the system to remote code execution through maliciously crafted SQL commands. This vulnerability classification aligns with CWE-89 which defines SQL injection as the insertion of malicious SQL code into application queries, enabling unauthorized access to database resources and potential system compromise. The affected parameters include news_id in news/send.php, thread_id in posts/edit.php, and user_email in both users/password.php and users/register.php, creating multiple attack vectors that adversaries can exploit to manipulate database operations.
The technical exploitation of these vulnerabilities occurs when user-supplied input is directly incorporated into SQL query construction without proper sanitization or parameterization. Attackers can manipulate the news_id parameter in news/send.php to inject malicious SQL payloads that bypass authentication mechanisms and potentially execute administrative commands on the database server. Similarly, the thread_id parameter in posts/edit.php allows manipulation of discussion thread data, while the user_email parameters in password and registration scripts provide opportunities to extract user credentials or manipulate account creation processes. These vulnerabilities specifically target the application's failure to implement proper input validation and parameterized queries, creating conditions where malicious SQL commands can be interpreted and executed by the database engine.
The operational impact of CVE-2013-7349 extends beyond simple data theft, as successful exploitation can lead to complete database compromise and potential system-wide infiltration. Remote attackers can leverage these vulnerabilities to extract sensitive user information including passwords, personal data, and system configuration details stored in the database. The vulnerability enables attackers to perform unauthorized database operations such as data modification, deletion, or extraction of confidential information, potentially leading to identity theft, service disruption, and unauthorized access to privileged accounts. Additionally, the presence of multiple vulnerable endpoints increases the attack surface and provides attackers with alternative exploitation paths, making the overall impact more severe than a single vulnerability.
Mitigation strategies for CVE-2013-7349 must prioritize immediate implementation of input validation and parameterized queries across all affected application components. The primary defense mechanism involves implementing proper parameterized queries or prepared statements that separate SQL code from user input, preventing malicious payloads from being executed as database commands. Input validation should include strict sanitization of all user-supplied parameters, with comprehensive filtering to reject suspicious characters and patterns commonly associated with SQL injection attacks. Organizations should also implement proper access controls and database permissions, ensuring that application database accounts have minimal required privileges and that audit logging is enabled to detect suspicious database activities. Network-level protections such as web application firewalls and intrusion detection systems can provide additional layers of defense, while regular security assessments and code reviews should be conducted to identify and remediate similar vulnerabilities in other application components, aligning with ATT&CK framework techniques that target credential access and execution phases of cyber attacks.
