Doc Text:
A flaw was found in Revive Adserver. An authenticated user with manager privileges can conduct a stored cross-site scripting (XSS) attack by injecting malicious script code into a tracker name. Because the application fails to properly encode tracker names when displaying maintenance check results, the script executes within an administrator's browser when the maintenance page is opened. This may allow an attacker to hijack administrative sessions or execute unauthorized administrative actions.

Description OSIDB Bzimport 2026-11-11 17:41:47 UTC
A stored cross-site scripting vulnerability in maintenance-appendcode-check.php in Revive Adserver 6.0.8 and earlier allows an authenticated manager to execute JavaScript in an administrator's browser. A manager can store a malicious tracker name and cause the tracker to appear in the append-code maintenance results. When an administrator opens the affected maintenance page, the tracker name is included in HTML without appropriate encoding. The issue is fixed in Revive Adserver 6.0.9 by HTML-encoding tracker names when displaying the maintenance results.
