Vulnerability Title
Acm-search-v2-rhel9: search-v2-operator: shell-command and sql injection in postgresql-start.sh via cr-supplied work_mem
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in acm-search-v2-rhel9. This vulnerability allows an authenticated attacker, such as a hub administrator or a Search Custom Resource (CR) editor, to inject malicious shell commands or SQL statements. This occurs because the WORK_MEM string provided in the Search CR is not properly validated before being used in a bash script and an SQL query. Successful exploitation could lead to arbitrary code execution within the privileged postgres pod, potentially compromising the system.
