Summary

CVE-2024-2330 is a medium-severity SQL Injection (CWE-89) vulnerability in Netentsec Application Security Gateway. Its CVSS base score is 6.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked in the top 3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2024-2330 is a SQL injection vulnerability affecting the Netentsec NS-ASG Application Security Gateway version 6.3. The flaw resides in an unspecified component of the file /protocol/index.php, where unsanitized input to the IPAddr parameter allows malicious SQL statements to be executed.

The issue can be triggered remotely by an authenticated attacker with low-privileged credentials. Successful exploitation yields limited read, write, and disruption capabilities against the underlying database, as reflected in the CVSS 6.3 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L). Public proof-of-concept code has been released, enabling straightforward reproduction.

Vendor advisories and patches are unavailable; the product maintainer was notified prior to disclosure but provided no response. The referenced technical write-ups and Vuldb entries contain only the original researcher’s reproduction steps and do not list work-arounds or fixed firmware versions.

EPSS currently stands at 0.9275 with a recorded peak of 0.9306, indicating sustained and elevated exploitation interest since publication.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover SQLi flaws before deployment but does not stop their introduction.

SI-10 Information Input Validation good match

Input validation directly stops untrusted data from reaching SQL query construction without neutralization.

SA-8 Security and Privacy Engineering Principles partial match

Secure engineering principles require parameterized queries and input sanitization that structurally eliminate SQLi.

SI-4 System Monitoring partial match

System monitoring can identify attempted SQLi exploitation via anomalous queries after the weakness exists.

PR.PS-06 mostly match
blocks

Secure SDLC practices directly target injection flaws during coding and review so largely prevent CWE-89 introduction, yet the single broad outcome leaves residual risk from incomplete neutralization techniques or missed edge cases.

PR.AT-02 partial match
blocks

Training raises developer awareness of SQLi risks and can reduce introduction likelihood (partial) but removes none of the actual coding flaw's risk by itself since technical neutralization is still required.
