Rule Category

BROWSER-PLUGINS -- Snort has detected suspicious browser plugin traffic, likely targeting the ActiveX plugin in Internet Explorer, though this could apply to any browser. Attackers have refined techniques to smuggle extensions into the Chrome Web Store, which they can then modify remotely once downloaded to add or activate malicious or spyware features. This can be similar to a Potentially Unwanted Application, as valuable data and network access is often allowed on a phone or browser without proper investigation. Some extensions also mimic more well-known and trusted ones (AdBlock, etc.)

Alert Message

BROWSER-PLUGINS Microsoft Office Access multiple control instantiation memory corruption attempt

Rule Explanation

The Microsoft Access Wizard Controls in ACCWIZ.dll in Microsoft Office Access 2003 SP3 and 2007 SP1 and SP2 do not properly interact with the memory-allocation approach used by Internet Explorer during instantiation, which allows remote attackers to execute arbitrary code via a web site that references multiple ActiveX controls, as demonstrated by the ImexGrid and FieldList controls, aka "Access ActiveX Control Vulnerability."
