Apache Commons Fileupload Vulnerabilities, remote code exec, exploit code
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I want to know exploite code of following vulnerabilities.
- https://issues.apache.org/jira/browse/FILEUPLOAD-279
It seems like this vulnerabilities be caused by deserialization vulnerabilities.
- https://www.tenable.com/security/research/tra-2016-12
I interested in whether this vulnerabilities is only object deserialization.
According to Integrating with ysoserial, it seems possible to attack by uploading file of serialized object payload.
Is this uploading file general file upload?
For example, below code.
// Upload file of serialized object payload in Web Browser by `input type="file"`
// Server Code
DiskFileItemFactory factory = new DiskFileItemFactory();
factory.setSizeThreshold(0);
ServletFileUpload upload = new ServletFileUpload(factory);
List items = upload.parseRequest(request); // **Here executing attack code??
...
Or is this uploading file receiving serialized object payload(and desirialize ) like Java RMI?
I think only when receiving serialized object payload.

The vulnerability in that situation appears to be the application deserialising untrusted data within a trusted access control context (acc). See Oracle's Secure Coding Guidelines for Java SE Guideline 8-5 / SERIAL-5: Understand the security permissions given to serialization and deserialization.
A quick look at the current source appears to indicate that the Serializable has been taken off that library, and it doesn't appear to have ever done any deserialisation itself (I could be wrong).
