Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match
prevent

Directly prevents SQL injection by requiring validation of user inputs in advance_search.php before incorporation into SQL queries.

SI-2 Flaw Remediation good match
prevent

Mandates timely remediation of the specific SQL injection flaw in the Personnel Property Equipment System v1.0.

SC-7 Boundary Protection partial match
prevent

Enables web application firewalls at system boundaries to inspect and block malicious SQL injection payloads targeting the vulnerable endpoint.

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.
attack.mitre.org →
T1213.006 Databases Collection
Adversaries may leverage databases to mine valuable information.
attack.mitre.org →
T1485 Data Destruction Impact
Adversaries may destroy data and files on specific systems or in large numbers on a network to interrupt availability to systems, services, and network resources.
attack.mitre.org →
T1565.001 Stored Data Manipulation Impact
Adversaries may insert, delete, or manipulate data at rest in order to influence external outcomes or hide activity, thus threatening the integrity of the data.
attack.mitre.org →
Why these techniques?

SQLi in public-facing web app directly enables T1190 exploitation; arbitrary queries facilitate DB data access (T1213.006), deletion (T1485), and stored data manipulation (T1565.001).

Deeper analysisAI

CVE-2026-26703 is a SQL Injection vulnerability (CWE-89) in the sourcecodester Personnel Property Equipment System version 1.0, specifically affecting the /ppes/admin/advance_search.php component. Published on 2026-03-02T15:16:36.657, it carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), marking it as critical due to its potential for severe impact.

Remote, unauthenticated attackers can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation allows high-impact compromise of confidentiality, integrity, and availability, enabling attackers to execute arbitrary SQL queries, potentially leading to unauthorized data access, modification, or deletion within the application's database.

A detailed bug report is available at https://github.com/Thirtypenny77/bug_report/blob/main/sourcecodester/personel-property-equipment-system/SQL-4.md. No specific mitigation or patch information is provided in the CVE details.
