Threat & Defense at a Glance
Threat & Defense Details
Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing uses SQL injection payloads against database interfaces, identifying and supporting fixes for SQL injection weaknesses.
Developer assessments and testing (including injection-focused techniques) identify improper neutralization of special elements, and the verifiable flaw remediation corrects them pre-deployment.
Validates query inputs to prevent SQL syntax or command manipulation.
Identifies indicators of injection attacks (command, SQL, LDAP, etc.) via anomaly and attack monitoring.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
SQL injection in a remotely accessible web app directly enables T1190 exploitation of the application for access; arbitrary SQL execution facilitates T1213.006 data collection from the backend database.
NVD Description
A vulnerability has been found in SourceCodester Sales and Inventory System up to 1.0. The impacted element is an unknown function of the file /add_sales_print.php. Such manipulation of the argument sid leads to sql injection. It is possible to launch…

Deeper analysisAI
CVE-2026-3753 is a SQL injection vulnerability in SourceCodester Sales and Inventory System up to version 1.0. The flaw affects an unknown function in the file /add_sales_print.php, where manipulation of the 'sid' argument enables SQL injection. Published on 2026-03-08, it has a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L) and maps to CWE-74 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-89 (SQL Injection).
A remote attacker with low privileges, such as an authenticated user, can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation allows arbitrary SQL query execution via the 'sid' parameter, resulting in low-level impacts to confidentiality (e.g., limited data exposure), integrity (e.g., minor data modification), and availability (e.g., minor denial of service).
VulDB advisories (ctiid.349731, id.349731, submit.768037) document the issue, and a proof-of-concept exploit is publicly available on GitHub at meifukun/Web-Security-PoCs/blob/main/Inventory-System/SQLi-AddSalesPrint-sid.md, noting that it may be used. The vendor site at sourcecodester.com provides context on the affected software, though no specific patches are detailed in the referenced sources.
The exploit disclosure heightens risk for exposed instances, as the PoC enables ready replication by practitioners testing defenses.
