Patch Radar priority: Urgent. - Web page: https://patchblox.com/security/cve/CVE-2024-39684 - Priority: Urgent - CVSS: 7.8 (Moderate) - EPSS: 0.0042 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Vendor exploitability assessment: Exploitation More Likely - Published: Jul 9, 2024 - Weakness: Integer Overflow or Wraparound - Vendor advisory: https://msrc.microsoft.com/update-guide/vulnerability/CVE-2024-39684 ## Description 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. ## Where
