Last modified Jun 17, 2026

CVE-2017-7981 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 16.13% chance of exploitation in the next 30 days.
