Exploitation Status
Actively exploited in the wild
- Confirmed by CISA's Known Exploited Vulnerabilities catalog on 2022-04-15. Federal agencies were required to remediate by 2022-05-06.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.

Remediation status
No patch has shipped for CVE-2018-7841 yet — track the schneider-electric u.motion builder advisory for a fixed release and apply the workarounds below in the meantime.
Mitigate without a patch
Until you can upgrade, make sure every query built from user input uses parameterised statements or a prepared-statement API rather than string concatenation, and reduce the database account's privileges so an injected query cannot read or alter data beyond what the feature needs. Alongside that, restrict the management interface to trusted networks and apply the vendor's recommended configuration mitigations.
