Kerim Mrabti's first goal of the season secured Birmingham a point in a 1-1 draw at Blackburn.
Chances were few and far between in an uninspiring encounter, with both goals coming from penalties gifted to the opposition.
Rovers took the lead through Adam Armstrong's penalty in the 55th minute after a clumsy Wes Harding foul. But former Birmingham man Amari'i Bell gave away an equally stonewall penalty in the 63rd minute, duly dispatched by Mrabti.
Derrick Williams hit the woodwork in stoppage time but, although Rovers stretched their unbeaten run to eight, they will see this as another missed opportunity to make up ground on the top six after a second straight home draw.
The Blues have won just once in their last eight games, but this fightback means they registered a first point in four matches.
Boss Tony Mowbray made six changes, including a return for Lewis Holtby in place of Bradley Dack, while Blues manager Pep Clotet made five changes of his own in a bid to halt a run of three straight defeats.
Both sides had early chances in a disjointed first half. Sam Gallagher lashed a half-volley over after a lovely pass from John Buckley, before Darragh Lenihan was deceived by a long ball that allowed Mrabti to race clear, but his effort from a tight angle was turned behind by Christian Walton.
Opposite number Connal Trueman produced a sensational reflex save on the half hour when Holtby's teasing cross was turned goalwards by visiting defender Harlee Dean, and the stopper's quick reaction reprieved his captain.
Lukas Jutkiewicz spurned a glorious chance before the break, diverting a free header over, before Trueman was in action again, saving a low, 20-yard Armstrong drive.
Birmingham fell behind 10 minutes after the restart but only had themselves to blame as Harding's ill-judged mis-timed tackle brought down Gallagher and gave referee Robert Jones an easy decision to award a spot-kick.
Armstrong did the honours, slamming the ball into the bottom-left corner for his sixth goal of the campaign.
In the season of giving, it was Blackburn's turn eight minutes later, when Bell's outstretched leg upended Jacques Maghoma.
Mrabti stepped up and sent Walton the wrong way, placing the ball into the right corner.
Neither side could grab the initiative, though. Joe Rothwell forced a fine save out of the impressive Trueman, before both sides had good chances in time added on.
First, Williams saw his header thunder against the crossbar, before Birmingham's Kristian Pedersen somehow engineered space to let fly with a shot from the edge of the area which was off target as the points were shared.
What the managers said...
Blackburn's Tony Mowbray: "Let's not beat about the bush, it wasn't a very good football match, I'd have to say. But when we got 1-0 up from the penalty, I was struggling to see how they were going to score an equaliser.
"Their selection suggested they were coming here to make sure they didn't take another 3-0 beating like they did in their last away game. I don't know what else to say. It was a poor game, I didn't enjoy watching it. We just have to move on. We'll be better as we move forward, so let's see how we go."
Birmingham's Pep Clotet: "I haven't seen it back and I don't know if it's a penalty or not, but the linesman saw it very clear. I thought Wes had the position, but unfortunately this happened and he lost the position and was forced into a tackle.
"But the good thing it showed the resilience the squad had because I thought we created clearer chances. We had the 1v1 with Kerim, Maghoma had a couple of chances in the first half, and Jukey (Lukas Jutkiewicz) when he was grabbed on the corner and could not put a good header on it."
