After Peter Michorl’s 42nd-minute opener for the Austrian hosts was cancelled out by a Gareth Bale penalty in first-half stoppage time, Son Heung-min put Spurs 2-1 up with a slotted finish in the 56th minute.
A dramatic finale then saw Johannes Eggestein bring things level in the 84th minute, Tottenham regain the lead two minutes later through Dele Alli’s spot-kick, and LASK subsequently equalise again in time added on at the end thanks to Mamoudou Karamoko.
A point was enough to see second-placed Tottenham qualify ahead of concluding their Group J campaign next week at home against leaders Royal Antwerp, who are two points better off than Jose Mourinho’s side after beating Ludogorets 3-1 in Belgium.
Leicester, who top Group G and had already booked a place in the last 32, were beaten 1-0 at Zorya Luhansk following a late Allahyar Sayyadmanesh goal – their bid to seal first place now goes to the final round of games, in which they host AEK Athens.
Braga, also now qualified, are level on 10 points with the Foxes in second after beating AEK 4-2 in Greece.
Already-eliminated Celtic remain winless after five games in Group H having surrendered a two-goal lead to lose 4-2 at AC Milan.
The Hoops stunned their opponents with goals from Tom Rogic and Odsonne Edouard in the first 14 minutes before efforts in quick succession from Hakan Calhanoglu and Samuel Castillejo had Milan level before the break.
Jens Petter Hauge scored the hosts’ third five minutes after the interval and, in the 82nd minute, substitute Brahim Diaz added their fourth.
Milan are now through along with table-toppers Lille, who beat Sparta Prague 2-1 at home.
In Group I, Villarreal secured progress with a 1-0 win at Sivasspor, while second-placed Maccabi Tel Aviv drew 1-1 at Qarabag.
In Group K, Dinamo Zagreb have qualified following a 2-0 win at Feyenoord, who have been replaced in second place by Wolfsberger, 1-0 victors at CSKA Moscow.
In Group L, Red Star Belgrade joined already-through Hoffenheim in the next round following a goalless draw between the sides in Serbia. The other match in the pool was a 2-1 win for Slovan Liberec at Gent.
