CVE-2024-30866 identifies a SQL Injection vulnerability in netentsec NS-ASG version 6.3, specifically through the /3g/menu.php web interface. SQL Injection (CWE-89) occurs when untrusted input is improperly sanitized and incorporated into SQL queries, allowing attackers to manipulate backend databases. In this case, the vulnerability enables an attacker with network access and low privileges (PR:L) to inject malicious SQL commands without requiring user interaction (UI:N). The attack vector is network-based (AV:N), meaning the attacker can exploit it remotely. The vulnerability impacts confidentiality and integrity by potentially exposing or altering sensitive data stored in the database, though it does not affect system availability. The CVSS 3.1 base score is 5.4 (medium severity), reflecting the moderate risk due to required privileges and limited impact scope. No patches or known exploits are currently available, indicating the vulnerability is newly disclosed. The affected product, netentsec NS-ASG, is typically used in network security and telecommunications environments, making the vulnerability relevant to organizations managing such infrastructure. Proper input validation, parameterized queries, and access controls are critical to mitigating this risk.

The primary impact of CVE-2024-30866 is the potential unauthorized disclosure and modification of sensitive data within the netentsec NS-ASG database. Attackers exploiting this SQL Injection flaw could extract confidential information, alter records, or escalate privileges within the affected system. Although availability is not impacted, the compromise of data confidentiality and integrity can lead to operational disruptions, regulatory non-compliance, and reputational damage. Organizations relying on netentsec NS-ASG for network security or telecommunications management may face increased risk of data breaches or manipulation of security policies. The requirement for low privileges reduces the attack complexity but limits the scope to insiders or authenticated users with minimal access, somewhat mitigating widespread exploitation. However, if combined with other vulnerabilities or weak access controls, the threat could escalate. The absence of known exploits currently reduces immediate risk but underscores the need for proactive mitigation.

1. Restrict network access to the /3g/menu.php endpoint using firewalls or network segmentation to limit exposure to trusted users only. 2. Implement strict input validation and sanitization on all parameters accepted by the /3g/menu.php script to prevent malicious SQL code injection. 3. Employ parameterized queries or prepared statements in the application code to eliminate direct concatenation of user input into SQL commands. 4. Enforce the principle of least privilege by reviewing and minimizing user permissions required to access the vulnerable functionality. 5. Monitor database logs and application logs for unusual query patterns or errors indicative of SQL Injection attempts. 6. Stay updated with vendor advisories for patches or updates addressing this vulnerability and apply them promptly once available. 7. Conduct regular security assessments and penetration testing focusing on web application inputs and database interactions. 8. Consider deploying Web Application Firewalls (WAFs) with SQL Injection detection capabilities as an additional protective layer.
