This CVE record has been updated after NVD enrichment efforts were completed. Enrichment data supplied by the NVD may require amendment due to these changes.
Description
A cross-site scripting (XSS) vulnerability in the CGI program of Zyxel ZyWALL/USG series firmware versions 4.30 through 4.72, VPN series firmware versions 4.30 through 5.31, USG FLEX series firmware versions 4.50 through 5.31, and ATP series firmware versions 4.32 through 5.31, which could allow an attacker to trick a user into visiting a crafted URL with the XSS payload. Then, the attacker could gain access to some browser-based information if the malicious script is executed on the victim’s browser.
Metrics
NVD enrichment efforts reference publicly available information to associate
vector strings. CVSS information contributed by other sources is also
