CVE-2023-2226: Velociraptor crashes while parsing some malformed PE or OLE files.

• Severity: medium (CVSS 5.3 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2023-04-21 · updated 2026-06-17
• Weakness: CWE-125

Description

Due to insufficient validation in the PE and OLE parsers in Rapid7's Velociraptor versions earlier than 0.6.8 allows attacker to crash Velociraptor during parsing of maliciously malformed files.  For this attack to succeed, the attacker needs to be able to introduce malicious files to the system at the same time that Velociraptor attempts to collect any artifacts that attempt to parse PE files, Authenticode signatures, or OLE files. After crashing, the Velociraptor service will restart and it will still be possible to collect other artifacts.

Affected products

• Rapid7 Velociraptor: before 0.6.8 — fixed in 0.6.8

How to fix

Upgrade to a fixed version: Rapid7 Velociraptor 0.6.8. Check the vendor advisory for mitigations.
