Exploitation Summary
EIP tracks 1 public exploit for CVE-2025-63914. PoCs published by WxDou.
AI-analyzed exploit summary The PoC demonstrates a ZIP bomb vulnerability in Cinnamon/kotaemon's `_may_extract_zip` function, allowing excessive resource consumption and denial of service. It includes steps to create a highly compressible payload and verify resource exhaustion.
Description
An issue was discovered in Cinnamon kotaemon 0.11.0. The _may_extract_zip function in the \libs\ktem\ktem\index\file\ui.py file does not check the contents of uploaded ZIP files. Although the contents are extracted into a temporary folder that is cleared before each extraction, successfully uploading a ZIP bomb could still cause the server to consume excessive resources during decompression. Moreover, if no further files are uploaded afterward, the extracted data could occupy disk space and potentially render the system unavailable. Anyone with permission to upload files can carry out this attack.
