Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 17.2th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2026-3710 is a SQL injection vulnerability in the code-projects Simple Flight Ticket Booking System 1.0, affecting an unknown function in the file /Adminadd.php. The issue arises from manipulation of the arguments flightno, airplaneid, departure, dtime, arrival, atime, ec, ep, bc, and bp, classified under CWE-74 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-89 (SQL Injection). It carries a CVSS v3.1 base score of 4.7 (AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L), indicating medium severity with network accessibility and low attack complexity but requiring high privileges.

Attackers with high-level privileges, such as administrative access, can remotely exploit this vulnerability over the network without user interaction. Successful exploitation allows limited impacts, including low-level disclosure of confidential information, minor integrity modifications, and slight availability disruptions on the affected system.

Advisories and details are available through references including VulDB entries (ctiid.349656, id.349656, submit.766298), a GitHub issue at github.com/Owen-YuanW/CVE/issues/4, and the project site at code-projects.org. The exploit has been publicly disclosed and may be actively used.

This vulnerability highlights risks in unauthenticated or poorly sanitized admin interfaces in open-source booking systems, with public exploit availability increasing potential for targeted abuse by privileged insiders or compromised accounts.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
Why these techniques?

SQL injection in publicly accessible web admin interface (/Adminadd.php) directly enables remote exploitation of a public-facing application by valid high-privilege accounts.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires validation of inputs (flightno, airplaneid, etc.) to the /Adminadd.php function, blocking the SQL injection vectors described in CWE-89.

prevent

Limits the number of accounts holding the high privileges (PR:H) needed to reach the vulnerable Adminadd.php endpoint, reducing the population that can exploit the flaw.

respondrecover

Mandates prompt identification and patching of the publicly disclosed SQL injection flaw in the Simple Flight Ticket Booking System code.
