AI-suggested
Users should avoid installing or upgrading hMailServer 6.3.7 into pre-existing folders writable by non-administrators. Installing under the default Program Files directory, which restricts write permissions, mitigates this vulnerability. Monitor vendor advisories for any forthcoming patches.
Description
Progressive Robot hMailServer 6.3.7 on Windows has incorrect default permissions in its installer when installing into pre-existing folders writable by non-administrators. This flaw allows a local authenticated user to execute code with administrator privileges during setup or upgrade by placing malicious libraries in the Bin folder before permissions are hardened. The default installation under Program Files is not affected.
