CVE-2008-2545

Skype < 3.8.0.139 - Unauthenticated Arbitrary Code Execution via Case-Sensitive File Extension Bypass

Title source: llm
STIX 2.1

Description

Skype 3.6.0.248, and other versions before 3.8.0.139, uses a case-sensitive comparison when checking for dangerous extensions, which allows user-assisted remote attackers to bypass warning dialogs and possibly execute arbitrary code via a file: URI with a dangerous extension that uses a different case.
