CVE-2021-31925Network attack vector

Unauthenticated service interruption via unvalidated admin input

Published Jul 7, 2021 · Updated Aug 3, 2024

Improper input validation in Pexip Infinity 25.x before 25.4 allows remote attackers to interrupt service through its administrative web interface. The administrative interface accepts untrusted request input without adequate validation, but Pexip has not published the affected field, handler, or failure mode. No authentication or user interaction is required, and the published impact is limited to loss of service rather than data disclosure or modification.
