CWE-119Published: October 19, 2010· Updated: Jun 16, 2026

9.3

CVSS v3.1

Official Description

An ActiveX control in RealNetworks RealPlayer 11.0 through 11.1, RealPlayer SP 1.0 through 1.1.4, and RealPlayer Enterprise 2.1.2 does not properly initialize an unspecified object component during parsing of a CDDA URI, which allows remote attackers to execute arbitrary code or cause a denial of service (uninitialized pointer dereference and application crash) via a long URI.

Technical Analysis

CVE-2010-3747 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A proof-of-concept (PoC) exploit exists for CVE-2010-3747. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.

From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
