Velociraptor Divide-by-Zero DoS Vulnerability in Pre-0.77.2 Versions

Sources read

Source agreement

Tam uyum

Evidence confidence

%55

Short explanation

A divide-by-zero vulnerability in Velociraptor prior to 0.77.2 can trigger a denial of service when malformed sparse files are expanded. No active exploitation is reported. Patch status is UNKNOWN due to lack of vendor confirmation.

Why does it matter?

Organizations using pre-0.77.2 Velociraptor versions are at risk of service disruption. Without a confirmed patch, systems remain exposed to potential DoS attacks via malformed file uploads. No evidence of active exploitation exists.

What should be done?

Apply vendor-provided patch for version 0.77.2 or later
Ensure only trusted clients upload files to Velociraptor
Monitor for unexpected server crashes or panic events

Note on uncertainty

Show the technical text from the sources

A rogue Velociraptor client can upload a malformed sparse file such that if the GUI attempts to expand the file, a panic occurs which may crash the server process. The problem is a Divide by Zero bug in the ShouldPadFile() function.
