Detailsinfo

A vulnerability, which was classified as very critical, was found in Tencent RapidJSON up to 1.1.0. This affects the function GenericReader::ParseNumber in the library include/rapidjson/reader.h of the component File Handler. The manipulation with an unknown input leads to a integer overflow vulnerability. CWE is classifying the issue as CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Tencent RapidJSON is vulnerable to privilege escalation due to an integer overflow in the `GenericReader::ParseNumber()` function of `include/rapidjson/reader.h` when parsing JSON text from a stream. An attacker needs to send the victim a crafted file which needs to be opened; this triggers the integer overflow vulnerability (when the file is parsed), leading to elevation of privilege.

The advisory is shared at msrc.microsoft.com. This vulnerability is uniquely identified as CVE-2024-39684 since 06/27/2024. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. It demands that the victim is doing some kind of user interaction.
