CVE-2010-4388

MEDIUM 4.3EPSS 1.46%

Does this matter?

Lower severity and a low EPSS score (1.46%). Track it; it rarely justifies an emergency change on its own.

Description

The (1) Upsell.htm, (2) Main.html, and (3) Custsupport.html components in RealNetworks RealPlayer 11.0 through 11.1, RealPlayer SP 1.0 through 1.1.5, and RealPlayer Enterprise 2.1.2 and 2.1.3 allow remote attackers to inject code into the RealOneActiveXObject process, and consequently bypass intended Local Machine Zone restrictions and load arbitrary ActiveX controls, via unspecified vectors.
