Official Description
Cybozu Mailwise 5.0.4 and 5.0.5 allows remote authenticated users to obtain sensitive e-mail content intended for different persons in opportunistic circumstances by reading Subject header lines within the user's own mailbox.
Technical Analysis
CVE-2013-4698 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-200): Information exposure vulnerabilities leak sensitive data to unauthorized actors.
