Description
The ChilkatHttp.ChilkatHttp.1 and ChilkatHttp.ChilkatHttpRequest.1 ActiveX controls in ChilkatHttp.dll 2.4.0.0, 2.3.0.0, and earlier in ChilkatHttp ActiveX expose the unsafe SaveLastError method, which allows remote attackers to overwrite arbitrary files. NOTE: some of these details are obtained from third party information.
