CVE-2026-5033
Published: 29 March 2026
Summary
CVE-2026-5033 is a medium-severity Injection (CWE-74) vulnerability in Sherlock Accounting System. Its CVSS base score is 6.9 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 25.9th 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 RA-5 (Vulnerability Monitoring and Scanning) and SI-10 (Information Input Validation).
Deeper analysis
CVE-2026-5033 is a SQL injection vulnerability affecting code-projects Accounting System 1.0. The issue resides in an unknown functionality of the file /view_costumer.php within the Parameter Handler component, where manipulation of the cos_id argument triggers the injection. Published on 2026-03-29, it is associated with CWEs-74 and CWE-89.
The vulnerability enables remote exploitation by unauthenticated attackers requiring low attack complexity and no user interaction. Exploitation of the cos_id parameter allows attackers to achieve low impacts on confidentiality, integrity, and availability, as reflected in its CVSS 3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L).

Why these techniques?
SQL injection in a public-facing web application (view_costumer.php parameter handler) directly enables remote unauthenticated exploitation for initial access.

SI-10 directly prevents SQL injection by requiring validation of untrusted inputs like the cos_id parameter in /view_costumer.php.
SI-2 mandates timely identification, reporting, and remediation of flaws such as this SQL injection vulnerability through patching.
RA-5 requires vulnerability scanning that would identify the SQL injection flaw in the Parameter Handler component.
