Lifecycle Timeline
1DescriptionCVE.org
A vulnerability was detected in lo48576 fbxcel up to 0.9.0. This affects an unknown part of the file src/pull_parser/v7400/parser.rs of the component Node Header Handler. The manipulation results in denial of service. The attack must be initiated from a local position. The exploit is now public and may be used. The pull request to fix this issue awaits acceptance.
AnalysisAI
Denial-of-service in fbxcel up to 0.9.0 allows a local, low-privileged attacker to crash any application embedding this Rust FBX-parsing library by supplying a crafted FBX file that triggers improper resource handling in the v7400 Node Header Handler. Impact is limited to availability with no confidentiality or integrity consequence, consistent with the CVSS 4.0 base score of 1.9. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires local system access and at minimum low-level privileges (PR:L per CVSS 4.0 vector) sufficient to supply a crafted FBX file as input to a running fbxcel-based application. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is very low. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A local user with low-level system privileges provides a specially crafted FBX file to an application that uses fbxcel for parsing. The malformed node header in the file triggers the CWE-404 flaw in the v7400 pull parser, causing the host application to crash or hang. … |
| Remediation | No vendor-released patched version has been confirmed at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
