CVE-2021-28829Network attack vector

End-user compromise via persistent CSV injection

Published Apr 20, 2021 · Updated Sep 16, 2024

CSV injection in TIBCO Administrator 5.10.2 and earlier, 5.11.0, and 5.11.1 allows remote authenticated users to compromise end users. The Administration GUI fails to neutralize attacker-controlled spreadsheet formulas before persistent CSV output; TIBCO does not identify the field or export path. Exploitation requires low-privileged network access and another user's interaction with the generated CSV, enabling commands, malware, data theft, or forged output.
