CVE-2008-4582

27
FAUCET Score

CVE-2008-4582 describes a Same Origin Policy bypass vulnerability affecting Mozilla Firefox versions 2.x before 2.0.0.18, 3.0.1 through 3.0.3, and SeaMonkey 1.x before 1.1.13 on Windows. This flaw allows user-assisted remote attackers to access sensitive information by tricking the browser into misinterpreting Windows .url shortcut files, particularly when referencing local or shared filesystem resources. With a CVSS score of 4.3, it has a medium attack complexity and could lead to information disclosure. While not actively exploited in the wild, an ExploitDB entry exists, and its EPSS score indicates a higher than average probability of exploitation, despite minimal community discussion or media coverage.
