CVE-2017-8920: n/a vulnerability

Security readout for executives and security teams

CGI:IRC versions before 0.5.12 can reflect user input from the R parameter into a web page without proper encoding. If a vulnerable irc.cgi page is reachable, an attacker could potentially trigger browser-side script execution in a user’s session. Exposure is likely limited to legacy CGI:IRC deployments with irc.cgi reachable over HTTP. The bundle does not identify specific vendors, packaged distributions, or CPEs beyond CGI:IRC before 0.5.12. Treat this as a legacy web exposure cleanup item. It is not supported by active exploitation evidence in the bundle, but public web-facing XSS can create user-trust and session-risk issues. Mitigation focus: Upgrade CGI:IRC to version 0.5.12 or a vendor-confirmed fixed build.; Confirm the deployed code includes the referenced upstream fix commit.; Remove or restrict public access to irc.cgi if upgrade status is uncertain..
