CVE-2010-2658: Opera before 10.60 does not properly restrict certain interaction between plug-ins, file inputs, and the cl...

Security readout for executives and security teams

This is an old Opera browser flaw affecting versions before 10.60. A malicious website could, with user involvement, abuse plug-ins, file upload controls, and clipboard behavior to cause a local file to be uploaded. The main business risk is legacy browser exposure on desktops or kiosks. Exposure is likely limited to systems still running Opera versions earlier than 10.60, especially legacy workstations, kiosks, or unmanaged endpoints. Modern environments are unlikely to be exposed unless old Opera installations remain in use. Treat as a legacy exposure cleanup item. It is not supported as actively exploited by the supplied sources, but affected browsers could expose local files if users browse malicious sites. Prioritize discovery and removal of obsolete Opera installations. Mitigation focus: Upgrade Opera installations to version 10.60 or later.; Remove unsupported Opera versions from managed endpoints.; Check vendor changelogs and advisory references for platform-specific guidance..
