CVE-2020-11548Public exploitNetwork attack vector

Client code execution via unneutralized CSV formulas

Published Apr 4, 2020 · Updated Aug 4, 2024

CSV injection in Search Meter 2.13.2 and earlier allows remote attackers to plant formulas that execute when an administrator opens an export. The plugin stores untrusted search-bar input and writes it into exported CSV cells without neutralizing formula-leading characters. Execution occurs on the administrator's workstation only after the statistics are exported, opened in Excel, and external data import is allowed.
