CVE-2017-7981 Information

Description

Tuleap before 9.7 allows command injection via the PhpWiki 1.3.10 SyntaxHighlighter plugin. This occurs in the Project Wiki component because the proc_open PHP function is used within PhpWiki before 1.5.5 with a syntax value in its first argument and an authenticated Tuleap user can control this value even with shell metacharacters as demonstrated by a ‘?plugin SyntaxHighlighter syntax=\c;id' line to execute the id command.
