- Issue
- A issue was discovered in SiteServer CMS prior to version 6.12. It allows remote attackers to execute arbitrary code because an administrator can add the permitted file extension .aassp, which is converted to .asp because the "as" substring is deleted.
Recommended action: Upgrade to 6.12 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
