SPIP before 4.4.18 contains an unauthenticated blind SQL injection vulnerability in the public sitemap endpoint where the MySQL escaper spip_mysql_cite() in ecrire/req/mysql.php returns values unescaped when the target column is a date type and the supplied value matches the pattern of a word character followed by an open parenthesis. Attackers can supply a crafted value such as a time-based payload through the annee parameter in squelettes-dist/sitemap.xml.html to embed arbitrary SQL directly into the generated query, enabling time-based and boolean-based blind SQL injection that can expose arbitrary database content including the alea_ephemere secret used to sign action nonces.
