| Description | 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. | Velociraptor's VQL has a query() plugin which allows running a VQL query in a different org or user context. To be able to run as a different user, the calling user needs to have the IMPERSONATE permission (usually only given to administrators). Velociraptor versions prior to 0.77.2 evaluate this permission against the caller's org instead of against the target org. This allows an administrator in one org to impersonate another user in another org, in which they may not have the IMPERSONATE permission. |
