CVE-2005-2269
HighSummary
Vulnerability in Firefox before 1.0.5, Mozilla before 1.7.9, and Netscape 8.0.2 involves improper verification of DOM node name types within the context of their namespaces. This allows a remote attacker to modify tag properties, potentially leading to arbitrary script or code execution, as demonstrated using an XHTML document with IMG tags with custom properties.
Risk Assessment
The risk for the organization includes the possibility of remote code execution in the user's browser, which could lead to data theft, malware infection, or session hijacking.
Recommendation
It is recommended to immediately update Firefox to version 1.0.5 or later, Mozilla to version 1.7.9 or later, and Netscape to a version newer than 8.0.2.

Original NVD description (English source)
Firefox before 1.0.5, Mozilla before 1.7.9, and Netscape 8.0.2 does not properly verify the associated types of DOM node names within the context of their namespaces, which allows remote attackers to modify certain tag properties, possibly leading to execution of arbitrary script or code, as demonstrated using an XHTML document with IMG tags with custom properties ("XHTML node spoofing").
