Seven-time European champions AC Milan have a two-point lead.
However, Inter, still smarting from a midweek Champions League home loss to Liverpool, have two games in hand and can reclaim pole position if they defeat Sassuolo on Sunday.
Brazilian midfielder Junior Messias gave Milan a fifth-minute lead before Federico Bonazzoli levelled with an overhead kick on the half-hour mark.
Giant Bosnian striker Milan Djuric headed Salernitana in front on 72 minutes before Milan salvaged a point thanks to a long-range effort by Ante Rebic five minutes later.
Salernitana, with their third coach of the season in Davide Nicola in charge, are still seven points from safety.

Teenagers Cristian Volpato and Edoardo Bove came to Roma's rescue as Jose Mourinho's side drew 2-2 with Verona.
With Verona 2-0 up, 18-year-old Volpato scored in the 65th minute, just three minutes after coming off the bench when he reacted fastest to a half-cleared corner.
Bove, 19, was then introduced in the 78th minute and six minutes later secured a point with a shot in off the post, again following a corner from Jordan Veretout.
Verona, coached by Igor Tudor, had been worth their 2-0 lead.
A free-kick, well-rehearsed on the training ground, from Czech star Antonin Barak gave them a fifth-minute lead. It was his 10th goal of the season.
