CVE-2000-0782: netauth.cgi program in Netwin Netauth 4.2e and earlier allows remote attackers to read arbitrary files via...

Security readout for executives and security teams

A very old flaw in Netwin's Netauth webmail management tool (version 4.2e and earlier) let a remote attacker view files on the server they should not see. The attacker only needed to send a specially crafted web request. Modern deployments of this legacy product are rare, so business impact today is mostly limited to any organization still running unpatched Netauth. Exposure is limited to hosts still running Netwin Netauth 4.2e or earlier with netauth.cgi reachable over HTTP. Given the product's age (2000-era webmail management), most enterprises no longer run it. Any remaining internet-exposed instance should be considered exposed to unauthenticated file disclosure. Low priority for most modern environments because Netwin Netauth is a legacy product rarely deployed today. If your organization confirms it is still running Netauth, treat remediation as moderate priority: it is an unauthenticated file-disclosure flaw on an internet-facing CGI. Mitigation focus: Apply the vendor update referenced at netwinsite.com/netauth/updates.htm or upgrade beyond 4.2e.; If patching is not possible, remove or restrict access to netauth.cgi at the web server.; Place any remaining Netauth instance behind a reverse proxy or WAF that blocks traversal sequences..
