Use of Externally-Controlled Format String


Severity High
Score 9.8/10


Some components in Dubbo will try to print the formatted string of the input arguments, which will possibly cause RCE for a maliciously customized bean with a special toString method. In the latest version, we fix the toString call in timeout, cache, and some other places. Fixed in Apache Dubbo 2.7.13, and 3.0.1.
