This Metasploit module exploits a heap based buffer overflow in the CrystalPrintControl ActiveX, while handling the ServerResourceVersion property. The affected control can be found in the PrintControl.dll component as included with Crystal Reports 2008. This Metasploit module has been tested successfully on IE 6, 7 and 8 on Windows XP SP3 and IE 8 on Windows 7 SP1. The module uses the msvcr71.dll library, loaded by the affected ActiveX control, to bypass DEP and ASLR.
e2e444f4f608cf2a5267e52972251a3f6dc63fb45578a2ac18f6eb5ad4684ec0Secunia Research has discovered a vulnerability in SAP Crystal Reports, which can be exploited by malicious people to compromise a user's system. The vulnerability is caused due to a boundary error in the "CrystalReports12.CrystalPrintControl.1" ActiveX control (PrintControl.dll) when processing the "ServerResourceVersion" property and can be exploited to cause a heap-based buffer overflow via an overly long string. Successful exploitation allows execution of arbitrary code. Affected is Crystal Reports 2008 SP3 Fix Pack 3.2 Print ActiveX (12.3.2.753).
