Summary

CVE-2025-15560 is a high-severity SQL Injection (CWE-89) vulnerability in Nestersoft Worktime. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 11.1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

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

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly prevents SQL injection by validating and sanitizing inputs to the vulnerable widget API endpoint before they reach the database backend.

SI-2 Flaw Remediation good match

prevent

Requires identification, reporting, and patching of the specific SQL injection flaw in the WorkTime server to eliminate the vulnerability.

AC-6 Least Privilege partial match

prevent

Enforces least privilege on the application's database service account, limiting the scope of data access or arbitrary SQL execution even if injection succeeds.

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 public-facing widget API endpoint directly enables remote exploitation of the application for data access and arbitrary SQL execution.

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1

NVD Description

An authenticated attacker with minimal permissions can exploit a SQL injection in the WorkTime server "widget" API endpoint to inject SQL queries. If the Firebird backend is used, attackers are able to retrieve all data from the database backend. If…

the MSSQL backend is used the attacker can execute arbitrary SQL statements on the database backend and gain access to sensitive data.

Deeper analysisAI

CVE-2025-15560 is a SQL injection vulnerability (CWE-89) in the WorkTime server's "widget" API endpoint, affecting instances configured with either a Firebird or MSSQL database backend. Published on 2026-02-19, it has a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant confidentiality, integrity, and availability impacts.

An authenticated attacker with minimal permissions can exploit the vulnerability over the network with low complexity and no user interaction required. When using the Firebird backend, the attacker can retrieve all data from the database. With the MSSQL backend, the attacker can execute arbitrary SQL statements on the database, enabling access to sensitive data.
