Lifecycle Timeline
6DescriptionCVE.org
Velociraptor's NTFS parsing library mishandles several out of bound and memory exhaustion bugs which may be triggered by maliciously crafted NTFS images.
Typically Velociraptor's NTFS parser is used on live NTFS filesystems, limiting the opportunity of attackers corrupting the filesystem. However, in some applications (e.g. dead disk forensics https://docs.velociraptor.app/docs/forensic/deaddisk/ ) Velociraptor may be used on untrusted NTFS image files.
If an attacker is able to inject maliciously corrupted NTFS Volumes they can cause a crash and a Denial of Service.
AnalysisAI
Out-of-bounds read and memory exhaustion flaws in Velociraptor's NTFS parsing library allow denial of service when processing maliciously crafted NTFS images. Specifically affects deployments using the dead disk forensics workflow where Velociraptor ingests untrusted NTFS image files rather than live filesystems. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that Velociraptor be used in dead disk forensics mode, specifically parsing an untrusted or attacker-controlled NTFS image file rather than analyzing a live NTFS filesystem. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-assigned CVSS score of 7.2 with vector AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H warrants scrutiny. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A threat actor who anticipates being the subject of a Velociraptor-based forensic investigation, or who has compromised a system that will later be imaged, crafts a malformed NTFS volume with carefully constructed record sizes or attribute lengths designed to trigger out-of-bounds reads or memory exhaustion. When a Velociraptor operator mounts this image during dead disk forensics, the parser crashes, denying the investigator use of the tool and potentially disrupting time-sensitive incident response. … |
| Remediation | Upgrade Velociraptor to version 0.77.2 or later, which contains the vendor-released patch addressing the out-of-bounds and memory exhaustion bugs in the NTFS parser. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all Velociraptor deployments and restrict analyst access to processing untrusted NTFS images until patching is complete. …
