CVE-2017-9805
HighCVSS 8.1KEVSummary
Wtyczka REST w Apache Struts w wersjach od 2.1.1 do 2.3.x przed 2.3.34 oraz 2.5.x przed 2.5.13 wykorzystuje XStreamHandler z instancją XStream do deserializacji bez filtrowania typów, co może prowadzić do zdalnego wykonania kodu podczas deserializacji ładunków XML.
Risk Assessment
Podatność ta może umożliwić atakującym zdalne wykonanie kodu na serwerze, co stwarza poważne zagrożenie dla bezpieczeństwa aplikacji i danych organizacji.
Recommendation
Zaleca się aktualizację Apache Struts do wersji 2.3.34 lub 2.5.13 lub nowszej, aby zniwelować ryzyko związane z tą podatnością.

Original NVD description (English source)
The REST Plugin in Apache Struts 2.1.1 through 2.3.x before 2.3.34 and 2.5.x before 2.5.13 uses an XStreamHandler with an instance of XStream for deserialization without any type filtering, which can lead to Remote Code Execution when deserializing XML payloads.
