Remote service interruption via unchecked indexIDNew length
Published Jul 2, 2026 · Updated Jul 2, 2026
Buffer overflow in UTT nv518G firmware nv518GV3v3.2.7-210919-161313 allows remote attackers to interrupt service via an HTTP request. The gohead sub_483ba0 handler accepts indexIDNew without validating its length, so an oversized form value overruns its destination buffer. The published request example contains no credential or session header, and the reported consequence is limited to service interruption.
