Official Description
The wininet.dll FTP client code in Microsoft Internet Explorer 5.01 and 6 might allow remote attackers to execute arbitrary code via an FTP server response of a specific length that causes a terminating null byte to be written outside of a buffer, which causes heap corruption.
Technical Analysis
CVE-2007-0217 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.
A proof-of-concept (PoC) exploit exists for CVE-2007-0217. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
