CVE-2007-2216

Status: ModifiedHigh (9.3)—💥 Exploit

The tblinf32.dll (aka vstlbinf.dll) ActiveX control for Internet Explorer 5.01, 6 SP1, and 7 uses an incorrect IObjectsafety implementation, which allows remote attackers to execute arbitrary code by requesting the HelpString property, involving a crafted DLL file argument to the TypeLibInfoFromFile function, which overwrites the HelpStringDll property to call the DLLGetDocumentation function in another DLL file, aka "ActiveX Object Vulnerability."

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
