Unauthenticated code execution via delsn SQL injection
Published Jul 1, 2026 · Updated Jul 1, 2026
SQL injection in UTT nv518G firmware nv518GV3v3.2.7-210919-161313 allows remote attackers to execute arbitrary code via delsn. The /gohead/sub_463bbc handler tokenizes the attacker-controlled delsn value and inserts each unsanitized token into an SQL string with sprintf. An unauthenticated network POST is sufficient, and the public proof of concept demonstrates a tautological SQL predicate; the record reports code execution.
