Horizon Alert
Summary of the vulnerability and why it matters
This advisory concerns a critical vulnerability in an e-commerce platform extension that allows unauthenticated attackers to upload arbitrary files. This could lead to remote code execution, malware hosting, or other security breaches on affected systems, impacting the integrity and availability of online stores.
- Unauthenticated file uploads can compromise e-commerce sites.
- It enables remote code execution and other serious attacks.
- Confirm relevance and assess exposure to this threat.
Attack Path
How an attacker could exploit the issue
An unauthenticated attacker can upload arbitrary files, including malicious scripts, to a Magento 2 store's media directory. This is possible because the Amasty Order Attributes extension does not properly validate file uploads through its endpoint. Successful exploitation could lead to remote code execution, malware hosting, or cross-site scripting.
- No authentication or special access required.
- Upload arbitrary files to the media directory.
- Remote code execution or malware hosting.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability could allow an unauthenticated attacker to upload arbitrary files to a Magento 2 store's media directory. If the server permits PHP execution in this directory, it could lead to remote code execution. Alternatively, attackers could host malware, conduct cross-site scripting attacks, or potentially write files outside the intended directory.
- Arbitrary files in the media directory.
- Unauthenticated file upload to the endpoint.
- Remote code execution or malware hosting.
