Status: ModifiedMedium (5)—💥 Exploit

Mozilla Firefox 3.0.6 through 3.0.13, and 3.5.x, allows remote attackers to cause a denial of service (CPU consumption) via JavaScript code with a long string value for the hash property (aka location.hash), a related issue to CVE-2008-5715.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
