Buffer overflow in the Steema TeeChart ActiveX control, as used in Schneider Electric Vijeo Historian 4.30 and earlier, CitectHistorian 4.30 and earlier, and CitectSCADAReports 4.10 and earlier, allows remote attackers to execute arbitrary code or cause a denial of service via unspecified vectors.

commandAddSeries()↗
  • →Detect instantiation of any of the five vulnerable TeeChart ActiveX CLSIDs in browser or document context; presence of these CLSIDs in registry or memory indicates a vulnerable/exploited control. ↗
  • →Monitor for calls to the AddSeries() method on TeeChart ActiveX objects with overly large or negative integer arguments, which triggers the integer overflow leading to arbitrary code execution. ↗
  • →The exploit is delivered via browser (drive-by) and targets IE8 with Java support for DEP bypass; monitor for TeeChart OCX files loaded within iexplore.exe process. ↗
  • ·The exploit vector requires social engineering to deliver the malicious content to the victim; purely network-based exploitation without user interaction is not applicable for the TeeChart buffer overflow (CVE-2011-4034). ↗
  • ·Multiple TeeChart OCX versions spanning back to 2001 are affected, so detection rules should cover all five listed CLSIDs/filenames rather than targeting only the latest version. ↗
