Summary
Heap type confusion vulnerability in Apache Fory C++ deserialization. A crafted input payload can bypass type compatibility checks during polymorphic smart-pointer deserialization, causing an object of an incompatible type to be treated as the declared base type. This may result in undefined behavior and potentially lead to denial of service or arbitrary code execution.
Risk Assessment
The risk includes potential denial of service or remote code execution in applications using Apache Fory C++ with polymorphic smart-pointer deserialization. An attacker could exploit this to gain control of the system or disrupt services.
Recommendation
Upgrade Apache Fory to version 1.5.0, which fixes this issue. Applications not using polymorphic smart-pointer deserialization are not affected.
Original NVD description (English source)
Heap type confusion vulnerability in Apache Fory C++ deserialization. This issue affects Apache Fory C++ versions from 0.14.0 before 1.5.0. A crafted input payload can bypass type compatibility checks during polymorphic smart-pointer deserialization, causing an object of an incompatible type to be treated as the declared base type. This may result in undefined behavior and potentially lead to denial of service or arbitrary code execution. Users are recommended to upgrade to Apache Fory 1.5.0, which fixes this issue. Applications not using Apache Fory C++ polymorphic smart-pointer deserialization are not affected.
