CVE-2022-2434
HighSummary
Wtyczka String Locator dla WordPressa jest podatna na deserializację nieufnych danych wejściowych za pomocą parametru 'string-locator-path' w wersjach do 2.5.0 włącznie. Umożliwia to nieautoryzowanym użytkownikom wywoływanie plików przy użyciu wrappera PHAR, pod warunkiem, że uda im się nakłonić administratora strony do wykonania akcji, która deserializuje i wywołuje dowolne obiekty PHP.
Risk Assessment
Podatność ta stwarza ryzyko, że atakujący mogą wykonać złośliwe działania na serwerze, jeśli uda im się przesłać plik z zserializowanym ładunkiem oraz wykorzystać lukę w POP chain. Może to prowadzić do poważnych naruszeń bezpieczeństwa i utraty danych.
Recommendation
Zaleca się aktualizację wtyczki String Locator do najnowszej wersji, aby usunąć tę podatność. Dodatkowo, warto wprowadzić ograniczenia dotyczące przesyłania plików oraz monitorować działania administratorów w celu zminimalizowania ryzyka ataków.

Original NVD description (English source)
The String Locator plugin for WordPress is vulnerable to deserialization of untrusted input via the 'string-locator-path' parameter in versions up to, and including 2.5.0. This makes it possible for unauthenticated users to call files using a PHAR wrapper, granted they can trick a site administrator into performing an action such as clicking on a link, that will deserialize and call arbitrary PHP Objects that can be used to perform a variety of malicious actions granted a POP chain is also present. It also requires that the attacker is successful in uploading a file with the serialized payload.
