RunAs (runas.exe) in Windows 2000 stores cleartext authentication information in memory, which could allow attackers to obtain usernames and passwords by executing a process that is allocated the same memory page after termination of a RunAs command. NOTE: the vendor disputes this issue, saying that administrative privileges are already required to exploit it, and the original researcher did not respond to requests for additional information

Security readout for executives and security teams

This issue concerns Windows 2000 RunAs potentially leaving usernames and passwords in memory after use. A later process might receive the same memory page and recover that information. Microsoft disputed the report, saying administrative privileges were already required, and the original researcher did not provide more evidence. Exposure appears limited to legacy Windows 2000 systems where RunAs is used with sensitive credentials. Modern Windows versions are not identified as affected in the provided sources. Organizations without Windows 2000 assets likely have no direct exposure from this CVE. Low immediate priority unless Windows 2000 remains in use. If it does, prioritize retirement or isolation because the platform is obsolete and credential exposure risk compounds other unsupported-system risks. Mitigation focus: Inventory and retire any remaining Windows 2000 systems.; Avoid using RunAs with privileged credentials on legacy hosts.; Restrict local logon and process execution to trusted administrators..
