CVE-2024-4883Public exploitNetwork attack vector

Unauthenticated code execution via arbitrary file write

Published Jun 25, 2024 · Updated Aug 1, 2024

Path traversal in Progress WhatsUp Gold 2023.1.0 through 2023.1.2 allows remote attackers to execute code through NmApi.exe. The unauthenticated WriteDataFile WCF operation combines attacker-controlled directory and file names without confinement, then writes attacker-supplied bytes to the resulting path. Network access to NmApi.exe on TCP port 9643 is sufficient to plant executable web content, which runs with the service account's privileges.
