TikiWiki versions before 1.8.5 (1.8.4, 1.8.3, and all earlier versions)
Remote attacker uploads malicious PHP script to temp directory bypassing file validation checks and executes it through web access
Upgrade TikiWiki to version 1.8.5 or later and implement strict file upload validation
If grep returns version strings matching 1.0-1.8.4 pattern, system is vulnerable; no output indicates version 1.8.5+ or TikiWiki not installed
