A flaw was found in Revive Adserver. Due to improper ownership checks and insufficient output encoding in the conversion statistics pages, an unauthenticated remote attacker could trick an authenticated user into following a crafted link. This reflected Cross-Site Scripting (XSS) vulnerability allows the attacker to execute arbitrary script code within the context of the victim's browser session.

Description OSIDB Bzimport 2026-11-11 17:41:22 UTC
A reflected cross-site scripting vulnerability in the conversion-statistics pages of Revive Adserver 6.0.8 and earlier allows an unauthenticated attacker to execute JavaScript in an authenticated user's browser by persuading them to visit a crafted URL. An incorrect ownership check validates the advertiser identifier instead of the supplied website identifier, allowing malicious website input to reach HTML output without appropriate encoding. A related output issue affects the hour parameter. The issue is fixed in Revive Adserver 6.0.9 by validating the correct website identifier and normalising the hour parameter before formatting.
