CVE-2024-39173Network attack vector

Unauthenticated code execution via input evaluation

Published Jul 18, 2024 · Updated Aug 2, 2024

Eval injection in 253153 calculator-boilerplate 1.0 allows remote attackers to execute arbitrary code through the calculator input field. The /routes/calculator.js handler supplies attacker-controlled input to JavaScript's eval function, causing the text to be interpreted as executable code. The exposed web API requires no authentication or user interaction, and successful requests execute code with the Node.js process's privileges.
