Description:
Some vulnerabilities have been reported in DWR (Direct Web Rendering), which can be exploited by malicious people to bypass certain security restrictions or cause a DoS (Denial of Service).
1) An error exists within the include/exclude functionality, which can be exploited to access restricted methods by sending a specially crafted request to DWR.
2) DWR does not set a maximum number of calls in a batch, which can be exploited to stop the servlet engine from responding due to memory consumption by sending specially crafted requests.
The vulnerabilities are reported in versions prior to 1.1.4.
Solution:
Update to version 1.1.4.
Provided and/or discovered by:
Reported by the vendor.
