An exploitable privilege escalation vulnerability exists in the WebPro functionality of Aspire-derived NEC PBXes, including all versions of SV8100, SV9100, SL1100 and SL2100 devices. A specially crafted HTTP POST can cause privilege escalation resulting in a higher privileged account, including an undocumented developer level of access.
