Summary

CVE-2025-36366 is a medium-severity Improper Neutralization of Special Elements in Data Query Logic (CWE-943) vulnerability in Ibm Db2. Its CVSS base score is 6.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 28th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) — see the control section below for these in your framework.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Input validation directly stops unneutralized special elements from reaching query logic.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require parameterized queries and input neutralization to prevent query-logic injection.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development catches injection vulnerabilities before release but does not itself implement the fix.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates input validation and query parameterization that directly prevent injection flaws.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for controls against injection and improper query construction.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles reduce the likelihood of query-logic flaws but do not prescribe the specific coding practice.

A.8.28 Secure coding partial match
prevents

Secure coding standards require proper neutralization of special elements in all data queries.

A.8.30 Outsourced development partial match
prevents

Outsourced development agreements can require secure coding practices, indirectly mitigating the weakness.
