The Internationalized Domain Name (IDN) display algorithm in Mozilla Firefox before 22.0 does not properly handle the .com, .name, and .net top-level domains, which allows remote attackers to spoof the address bar via unspecified homograph characters.

Security readout for executives and security teams

CVE-2013-1699 is an old Firefox address-bar spoofing issue. Firefox before 22.0 could display certain internationalized domain names under .com, .name, and .net in a misleading way, enabling convincing lookalike domains for phishing. The bundle provides no CVSS score and no active exploitation evidence. Exposure is likely limited to legacy systems running Mozilla Firefox before 22.0 or old vendor-packaged Firefox builds. Modern managed browsers should not be affected if routinely patched. Long-lived kiosks, frozen virtual desktop images, and unsupported Linux endpoints are the main places to check. Treat this as a legacy hygiene and phishing-risk issue. It should not displace urgent actively exploited vulnerabilities, but any remaining Firefox pre-22 installations represent unacceptable browser debt and should be removed or updated. Mitigation focus: Upgrade Mozilla Firefox to version 22.0 or later.; Apply relevant Ubuntu or openSUSE Firefox security updates where applicable.; Retire unsupported browser builds from managed endpoints..
