Report Reveals cPanel/WHM Suffers "Multiple Vulnerabilities"

cPanelSecurity research firm Fortbridge has released a report claiming to have discovered “multiple vulnerabilities in cPanel/WHM”.

The report states:

“Our team has found multiple vulnerabilities in cPanel/WHM during a black-box pentest, the most important one being a privilege escalation via stored XSS. Whilst disclosing these bugs to the cPanel/WHM team, we discovered the pentested cPanel account was a reseller account with the permission to edit locales, thus this is not a default setting. The XSS vulnerability which we will present is considered a feature, and it was not fixed. We will show how this “feature” can be abused to escalate privileges to root, together with the rest of our findings.”

The report is quite detailed and shows in-depth the path they take to conduct the attack.

So what do you think – is this indeed a “feature” or is it a genuine bug?  cPanel has disputed the severity of this issue.
