CVE-2003-0101: n/a vulnerability

CVE-2003-0101: miniserv.pl in (1) Webmin before 1.070 and (2) Usermin before 1.000 does not properly handle metacharacters...

miniserv.pl in (1) Webmin before 1.070 and (2) Usermin before 1.000 does not properly handle metacharacters such as line feeds and carriage returns (CRLF) in Base-64 encoded strings during Basic authentication, which allows remote attackers to spoof a session ID and gain root privileges.

Security readout for executives and security teams

This is an old but severe Webmin/Usermin authentication flaw. If an affected admin interface is still running, a remote attacker could bypass normal trust in session handling and obtain root-level control. The business risk is concentrated in legacy, exposed management servers. Exposure is likely limited to legacy systems running Webmin before 1.070 or Usermin before 1.000, especially if reachable from the internet or broad internal networks. The provided affected-product metadata is incomplete, so asset inventory is essential. Prioritize any exposed legacy Webmin/Usermin systems immediately. If no affected versions are present, residual risk is low. If affected versions are reachable, the potential outcome is full server takeover. Mitigation focus: Upgrade Webmin to 1.070 or later and Usermin to 1.000 or later.; Apply fixed distribution packages referenced by Debian, Mandrake, Gentoo, HP, EnGarde, or SGI advisories.; Remove internet exposure for Webmin/Usermin management interfaces wherever possible..
