Vulnerable software:
Origin Client
Client/Desktop applications / Games

Vendor: Electronic Arts

Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

An issue was discovered in Electronic Arts Origin before 10.5.39. Due to improper sanitization of the origin:// and origin2:// URI schemes, it is possible to inject additional arguments into the Origin process and ultimately leverage code execution by loading a backdoored Qt plugin remotely via the platformpluginpath argument supplied with a Windows network share.

Mitigation
Install update from vendor's website.

Vulnerable software versions

Origin Client: 10.5.2 - 10.5.38
