CVE-2022-31794Network attack vector

Unauthenticated command execution via unitName shell injection

Published Jun 20, 2022 · Updated Aug 3, 2024

Command injection in Fujitsu ETERNUS CentricStor CS8000 Control Center before 8.1A SP02 P04 allows remote attackers to execute commands. The requestTempFile function in hw_view.php passes the unitName POST value directly to shell_exec without validation, permitting shell metacharacters and command substitutions. Direct network access to the PHP script is sufficient without authentication, and successful execution runs with limited www-data privileges on the appliance.
