CVE-2017-9305 describes a cross-site scripting (XSS) filter bypass vulnerability in Tiki Wiki CMS Groupware version 16.2. Attackers can exploit this by injecting padded zero characters into the lib/core/TikiFilter/PreventXss.php component, specifically demonstrated against tiki-batch_send_newsletter.php. Rated as Medium severity (CVSS 6.1), it requires user interaction (UI:R) but can be exploited remotely (AV:N) with low attack complexity (AC:L), potentially leading to limited confidentiality and integrity impacts. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
