CVE-2005-0146: Firefox before 1.0 and Mozilla before 1.7.5 allow remote attackers to obtain sensitive data from the clipbo...

Security readout for executives and security teams

This flaw let a malicious web page cause old Firefox or Mozilla browsers to paste clipboard contents into page-controlled context on systems where middle-click pastes. The business risk is unintended exposure of copied secrets, credentials, or sensitive text from very old browser installations. Exposure is mainly legacy environments still running Firefox before 1.0 or Mozilla before 1.7.5, especially Unix-like desktops configured for middle-click paste. Modern managed browser fleets are unlikely to be exposed, but archival systems and unsupported workstations should be checked. Treat this as a legacy-risk cleanup item, not an emergency, unless old Mozilla-era browsers still exist in sensitive environments. Prioritize removing unsupported browsers that could expose copied secrets during web browsing. Mitigation focus: Upgrade Firefox to 1.0 or later if any pre-1.0 installations remain.; Upgrade Mozilla to 1.7.5 or later if any older installations remain.; Apply relevant vendor updates from Mozilla or Red Hat advisories..
