摘要

An integrity verification vulnerability in OpenSignLabs OpenSign through 2.37.0 allows unauthenticated remote attackers to forge document audit-trail entries via the triggerevent Parse cloud function. The function accepts viewer identity and IP address as caller-supplied parameters without authentication, allowing fabrication of arbitrary audit log entries. An attacker can tamper with the legal audit trail of any signed document, undermining non-repudiation.
