CVE-2024-45277Network attack vector

Application interruption via nestTables prototype pollution

Published Oct 8, 2024 · Updated Oct 8, 2024

Prototype pollution in SAP HANA Client 2.0.0 through 2.21.30 allows remote authenticated users to interrupt Node.js applications. The nestTables path fails to sanitize attacker-controlled input before adding arbitrary properties to global object prototypes. Exploitation requires low privileges and an application that enables nestTables; no data disclosure or modification is reported.
