JustSystems JUST Online Update, as used in Ichitaro through 2014 and other products, does not properly validate signatures of update modules, which allows remote attackers to spoof modules and execute arbitrary code via a crafted signature.
Technical Analysis
CVE-2014-2003 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.
