Unauthenticated privilege escalation via phpcgi_main
Published Jul 31, 2023 · Updated Aug 2, 2024
Authentication bypass in D-Link DIR-859 Firmware 1.05b03 allows remote attackers to gain elevated privileges through phpcgi_main. Public records identify phpcgi_main as the affected locus but do not disclose the authorization check or untrusted input it mishandles. The attack requires network reachability and no prior authentication; successful exploitation grants elevated privileges, but the accessible functions are undisclosed.
