Manchester United's disappointing run of form persisted at Leeds' fortress, but head coach Ruben Amorim had his Brazilian forward to thank for his side avoiding even more damage against their old rivals.
The Everton loanee headed a first-half effort against the woodwork for the in-form hosts before the American midfielder applied a cool finish with a driven, 62nd-minute effort.
With the goal, the United boss was under intense scrutiny after his side had failed to beat struggling Wolves at home earlier in the week.
However, against a team who had two days less to prepare, the forward levelled three minutes after the opener when he ran on to a through ball from substitute the Dutchman and guided a shot underneath rushing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth Premier League goal since his big-money summer move and came at a time when Amorim is without several key attacking players due to a mix of fitness issues and international duty.
Not that the hosts to care about that given their own lack of preparation time.
Noah Okafor forced a full length save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when Benjamin Sesko, who is struggling to make an impact, turned his teammate's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the contest, also blasted against a post late on.
The point prolongs Leeds' unbeaten run to seven matches, their longest such streak since over two decades ago, and takes them a significant margin clear of the drop zone.
For the Manchester United though, it was yet another chance to move into fourth spot, albeit only for a short time, squandered.
Man Utd Analysis: Amorim's Side Struggle Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be understood for hoping the participating nations make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other attackers is having on the team's options.
It's not that the missing pair are the solution to all of United's problems. After all, they were part of the side that suffered poor results earlier in the campaign.
But without them, Amorim has limited attacking options.
He clearly does not have full faith in youngster Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward provided the assist for the equaliser almost instantly after his arrival as a replacement.
That leaves the Brazilian, who has now scored three goals in five games, and others playing out of their natural positions, alongside Sesko.
On this showing, the expensive frontman looks no better than previous struggling signings, lacking in confidence and conviction in front of goal.
Sesko's failure to turn home the cross means it is now a long run without a goal for the young striker.
Leeds United Breakdown: Another Step Towards Survival
After thrilling victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a bit drab affair.
True, there were instances of expected fervor, but the intimidating edge was not as evident as in other fixtures.
The home fans were more preoccupied about their side's inability to get sustained possession in dangerous areas for any length of time.
The striker's header that clipped the post was an rare moment of quality in a congested first half.
It still felt as though the hosts were finding it tough when a mistake opened the door for Aaronson.
Ever so briefly, The home ecstatic fans thought they were about to secure a coveted win against their old foes.
Nevertheless, there is a much bigger picture for the manager and Leeds to deal with.
When they endured a difficult run of form earlier in the campaign, many speculated about the manager's future.
Instead, he is now overseeing clear progress.
The task is not completed yet but gradually, Leeds are getting nearer to securing their survival.
