CVE-2024-21109Network attack vector

Unauthenticated data disclosure via undisclosed HTTP flaw

Published Apr 16, 2024 · Updated Dec 6, 2024

Information disclosure in Oracle VM VirtualBox before 7.0.16 allows remote attackers to read accessible data via crafted HTTP traffic. Oracle identifies the affected locus only as the Core component and has not disclosed which HTTP handler or operation mishandles untrusted input. Exploitation requires no authentication or user interaction but has high attack complexity, and the reported consequence is limited to reading VirtualBox-accessible data.
