Summary

CVE-2025-47295 is a low-severity Buffer Over-read (CWE-126) vulnerability in Fortinet Fortios. Its CVSS base score is 3.7 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique OS Credential Dumping (T1003); ranked at the 48th 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 SA-11 (Developer Testing and Evaluation) and SA-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation (static analysis, fuzzing, bounds checking tests) directly finds buffer over-read flaws.

SA-8 Security and Privacy Engineering Principles partial match

Engineering principles such as memory-safe design and bounds-checked abstractions structurally stop introduction of out-of-bounds reads.

SC-39 Process Isolation partial match

Process isolation limits the blast radius of an over-read to the compromised domain.

SI-10 Information Input Validation partial match

Input validation enforces length and index constraints that prevent many externally triggered over-reads.

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 development practices directly prevent introduction of buffer over-read weaknesses.

ID.RA-01 partial match
prevents

Vulnerability identification processes can discover buffer over-read flaws via scanning or review.

PR.PS-02 partial match
prevents

Patching or replacing vulnerable software removes known instances of buffer over-read bugs.

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 can detect buffer over-reads before release.

A.8.15 Logging partial match
finds

Logging can record evidence of an out-of-bounds read but does not prevent the weakness itself.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC mandates input validation and bounds checking that can prevent buffer over-reads.

A.8.26 Application security requirements partial match
prevents

Application security requirements can specify buffer-size and bounds-checking rules.

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

Secure architecture principles include memory-safety and bounds-checking design choices.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly require bounds-checked buffer access, mitigating over-reads.
