Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

CA-8 Penetration Testing
addresses: CWE-89

Penetration testing uses SQL injection payloads against database interfaces, identifying and supporting fixes for SQL injection weaknesses.

CM-11 User-installed Software
addresses: CWE-494

Policies can require integrity verification of software prior to installation, reducing risks from unverified downloads.

CM-14 Signed Components
addresses: CWE-494

Blocks installation of components lacking a valid signature, mitigating download or installation of code without integrity checks.

PM-30 Supply Chain Risk Management Strategy
addresses: CWE-494

Acquisition and maintenance portions of the strategy drive requirements for integrity verification of downloaded or supplied code.

SA-10 Developer Configuration Management
addresses: CWE-494

Mandating integrity control and approved-only changes during development prevents incorporation of code or components lacking integrity validation.

SA-12 Supply Chain Protection
addresses: CWE-494

Supply chain protection requires integrity verification of acquired components, directly reducing insertion or tampering of malicious code during delivery.

SA-13 Trustworthiness
addresses: CWE-494

Reduces exposure to code obtained without integrity verification by requiring assurance processes that confirm authenticity and absence of tampering.

SA-18 Tamper Resistance and Detection
addresses: CWE-494

Tamper resistance and detection commonly include integrity verification of code and firmware obtained from external sources.

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.

ID.RA-09 full match
prevents

Directly requires assessing authenticity/integrity of software before acquisition and use, preventing unverified downloads.

PR.DS-02 mostly match
prevents

Requires cryptographic integrity protections (signatures/hashes) for data-in-transit, covering downloaded code.

PR.PS-05 mostly match
prevents

Prevents execution of unauthorized software, blocking the outcome of an unchecked download.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly target injection flaws during coding and review so largely prevent CWE-89 introduction, yet the single broad outcome leaves residual risk from incomplete neutralization techniques or missed edge cases.

PR.AT-02 partial match
prevents

Training raises developer awareness of SQLi risks and can reduce introduction likelihood (partial) but removes none of the actual coding flaw's risk by itself since technical neutralization is still required.

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

The same secure-coding and static-analysis activities surface missing neutralization of SQL metacharacters before the system is accepted.

A.5.21 Managing information security in the ICT supply chain partial match
prevents

Mandating integrity checks, digital signatures, and origin tracing for ICT components directly reduces the chance that code or firmware lacking an integrity check will be accepted into the organisation’s environment.

A.5.6 Contact with special interest groups partial match
prevents

Early warnings and shared best-practice information help organizations apply the latest remediation techniques against SQL-injection vulnerabilities.

A.5.7 Threat intelligence partial match
prevents

Threat-intelligence feeds that surface new SQL-injection campaigns enable rapid updates to query-construction defenses and detection signatures before exploitation occurs.

A.8.25 Secure development life cycle partial match
prevents

Secure-coding rules and security testing phases mandate the use of parameterized queries or equivalent escaping, preventing the construction of dynamic SQL statements from untrusted input.

A.8.28 Secure coding partial match
prevents

Language-specific secure coding rules, peer review and SAST together prevent the construction of SQL statements from untrusted data without proper parameterization or escaping.
