CVE-2008-4388

CWE-20Published: January 20, 2009· Updated: Jun 16, 2026

9.3

CVSS v3.1

Official Description

The LaunchObj ActiveX control before 5.2.2.865 in launcher.dll in Symantec AppStream Client 5.2.x before 5.2.2 SP3 MP1 does not properly validate downloaded files, which allows remote attackers to execute arbitrary code via the installAppMgr method and unspecified other methods.

Technical Analysis

CVE-2008-4388 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-2008-4388. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
