Critical CVSS 9.1
CVE-2026-28310
SolarWinds Serv-U is affected by a privilege escalation vulnerability that allows a domain administrator to escalate their user type to that of a system administrator. The impact is lower in Windows deployments.
What this means
- Exposure
- Exploitable remotely over the network, with a privileged account and with no action from the victim.
- Impact
- An attacker can read sensitive data, modify or destroy data and take the service offline. The impact spreads beyond the vulnerable component into other parts of the system.
- Weakness
- No authorisation check happens before the action.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
