SPIP SPIP

SPIP < 4.4.18 Unauthenticated Blind SQL Injection via sitemap.xml.html

CVSS 4.0
8.7High

Official description

SPIP before 4.4.18 contains an unauthenticated blind SQL injection vulnerability in the SQL escaping layer that allows unauthenticated attackers to inject arbitrary SQL by supplying a crafted annee parameter value matching a word character followed by an open parenthesis, which bypasses escaping for date-type columns across MySQL, SQLite, and PostgreSQL backends. Attackers can exploit the always-present sitemap.xml.html template's annee criterion to embed unescaped time-based or boolean payloads into database queries, enabling extraction of arbitrary database content including the alea_ephemere secret used to sign SPIP action nonces.
