Privilege escalation via approximate numeric overflow check
Published Jul 9, 2024 · Updated Sep 5, 2024
Integer overflow in Tencent RapidJSON 1.1.0 and earlier allows local users to gain privileges when a victim opens crafted JSON. GenericReader::ParseNumber in include/rapidjson/reader.h uses an approximate limit while converting long numeric input, allowing the resulting double to overflow to infinity. Exploitation requires user interaction with the crafted file and gains the permissions available to the consuming application.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <=1.1.0
- Affected versionversion=<= 1.1.0
