CVE-2020-5282

Arbitrary shell execution via npm command

Published Mar 25, 2020 · Updated Aug 4, 2024

OS command injection in Nick Chan Bot before 1.0.0-beta allows local users to execute arbitrary shell commands through the npm command. The public advisory identifies the npm command as the vulnerable locus but does not disclose how it constructs or invokes a shell command from untrusted input. Exploitation requires local low-privileged access and user interaction, and successful command execution compromises bot confidentiality and integrity.
