Remote privilege escalation via redirect enablement
Published Sep 6, 2026 · Updated Sep 8, 2026
Improper privilege management in Tenda CP3 27.5.57.101 allows remote authenticated users to gain elevated privileges over the network. The CRedirServer::SetRedirectEnable function in Functions/Redirect.cpp processes an undisclosed input, but public sources do not explain the incorrect privilege assignment. Exploitation requires high-privilege authentication; the exact post-exploitation operations remain undisclosed.
