If your DM has you make a lot of stat checks then any stat that's super low becomes a weakness. Published modules rarely did that though so INT and CHR were easy dump stats for any class that didn't require them. The Basic line of games gave you bonuses starting at 13 but in 1E you generally needed at least a 15. STR is even worse in 1E; to get a +1 to both hit and damage you need a 17.
1E wasn't very stat dependent though. It's main purpose was class qualification. How does having an INT of 4 hurt you? Well, it means you're a fighter. Outside of that, it doesn't hurt you at all. There's no skill system and published modules rarely (if ever) ask for stat checks. If anything, modules would say things like, "The party has a 25% chance to notice X, 75% if a thief is present". The other main benefit of stats was qualifying for the XP bonus.
