Summary
Fortinet FortiSandbox 5.0.0 through 5.0.5, FortiSandbox 4.4 all versions, and FortiSandbox PaaS 5.0.1 through 5.0.5 contain an insufficiently protected credentials vulnerability. An authenticated administrator may read LDAP server credentials via client-side inspection.
Risk Assessment
An authenticated administrator could obtain LDAP credentials, potentially leading to privilege escalation or unauthorized directory access. However, valid administrative privileges are required.
Recommendation
Update FortiSandbox to a patched version. Restrict administrative privileges to the minimum necessary and rotate LDAP credentials.
