[BUG] app_icon is missing for iOS-ipa Static scans #2397

Open syselement opened 5 months ago

syselement commented 5 months ago

ENVIRONMENT

OS and Version: Linux ubuntu-ad 6.8.0-35-generic
Python Version: 3.12.3
MobSF Version: v4.0.3 (since v3.7.6)

EXPLANATION OF THE ISSUE

Any IPA scanning generates a PNG file for the icon but it results unreadable (CgBI format).
This is happening since v3.7.6 both with docker image and with local build from scratch.

STEPS TO REPRODUCE THE ISSUE

1. Run mobsf with persistence

`docker run -it --rm --name mobsf -p 8000:8000 -v ~/docker/mobsf:/home/mobsf/.MobSF opensecurity/mobile-security-framework-mobsf:latest`

2. Upload `UnCrackable-Level1.ipa` (any ipa has the bug) file and wait for scanning completion.

3. Generated icon is missing/error.

4. Icon has **CgBI** file format, Apple's proprietary PNG extension.

I have tried the CgbiPngFix tool and it's working. You could integrate it someway in MobSF.

It’s Apple proprietary. I don't know of any lib or utility that does this in non apple ecosystem, the last time I checked. Closing this since we cannot address this today.

Yeah, got it. Have you tried https://github.com/poolqa/CgbiPngFix ?

Interesting, let me take a look at this.
