CVE-2013-5674
HighSummary
W pliku badges/external.php w Moodle 2.5.x przed wersją 2.5.2 występuje problem z obsługą obiektu uzyskanego przez deserializację opisu zewnętrznej odznaki. To umożliwia zdalnym atakującym przeprowadzenie ataków typu PHP object injection poprzez nieokreślone wektory.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do modyfikacji parametrów, co może prowadzić do nieautoryzowanego dostępu lub manipulacji danymi użytkowników. To stwarza poważne ryzyko dla integralności systemu oraz danych użytkowników.
Recommendation
Zaleca się aktualizację Moodle do wersji 2.5.2 lub nowszej, aby usunąć tę podatność. Dodatkowo warto przeprowadzić audyt bezpieczeństwa aplikacji w celu identyfikacji innych potencjalnych zagrożeń.

Original NVD description (English source)
badges/external.php in Moodle 2.5.x before 2.5.2 does not properly handle an object obtained by unserializing a description of an external badge, which allows remote attackers to conduct PHP object injection attacks via unspecified vectors, as demonstrated by overwriting the value of the userid parameter.
