CVE-2006-2538

Status: ModifiedLow (2.6)—

IE Tab 1.0.9 plugin for Mozilla Firefox 1.5.0.3 allows remote user-assisted attackers to cause a denial of service (application crash), possibly due to a null dereference, via certain Javascript, as demonstrated using a url parameter to the content/reloaded.html page in a chrome:// URI. Some third-party researchers claim that they are unable to reproduce this vulnerability.

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).
