I WordPress-tilf\u00f8jelsen Ninja Forms, som har over en million aktive installationer, er der opdaget en kritisk s\u00e5rbarhed (CVE endnu ikke tildelt), der g\u00f8r det muligt for en uautoriseret bes\u00f8gende at f\u00e5 fuld kontrol over hjemmesiden. Problemet er l\u00f8st i versionerne 3.0.34.2, 3.1.10, 3.2.28, 3.3.21.4, 3.4.34.2, 3.5.8.4 og 3.6.11. Det bem\u00e6rkes, at s\u00e5rbarheden allerede bliver udnyttet til angreb, og for hurtigt at blokere problemet har udviklerne af WordPress-platformen indf\u00f8rt en tvungen automatisk opdatering p\u00e5 brugernes sider. <\/p>\n

S\u00e5rbarheden skyldes en fejl i implementeringen af Merge Tags-funktionaliteten, som g\u00f8r det muligt for uautentificerede brugere at kalde visse statiske metoder fra forskellige klasser i Ninja Forms (for at kontrollere om metoderne blev n\u00e6vnt i de data, der blev sendt via Merge Tags, blev funktionen is_callable() kaldt). Der var ogs\u00e5 adgang til at kalde en metode, der deserialiserer indhold, sendt af brugeren. Ved at sende specialdesignede serialiserede data kunne angriberen inds\u00e6tte sine egne objekter og f\u00e5 PHP-kode til at blive udf\u00f8rt p\u00e5 serveren<\/a> eller slette vilk\u00e5rlige filer i kataloget med hjemmesideoplysninger.
