AnalysisAI

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. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.

RemediationAI

No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate array indices and buffer lengths. Use memory-safe languages. Enable AddressSanitizer during testing.

Technical ContextAI · show details

This vulnerability is classified as Out-of-bounds Read (CWE-125), which allows attackers to read data from memory outside the intended buffer boundaries. 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 include: Rapid7 Velociraptor.

Attack Technique

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
