CVE-2023-22877

Command execution via unneutralized CSV formulas

Published Aug 28, 2023 · Updated Sep 16, 2024

CSV injection in IBM InfoSphere Information Server 11.7 allows remote attackers to execute commands through crafted CSV content. The affected export locus is undisclosed; it fails to neutralize formula-leading values before writing attacker-controlled data into a CSV file. Execution requires user interaction when the generated file is opened in spreadsheet software, and resulting commands run in the local user's context.
