CVE-2026-34915
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA missing sanitisation of user input in the zone-include.php script of Revive Adserver 6.0.6 and earlier could allow a low‑privileged user to exploit the clientid parameter to perform blind SQL injection attacks. Input sanitisation has been improved to ensure that all parameters processed by the script are properly validated.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA blind SQL injection vulnerability exists in zone-include.php of Revive Adserver 6.0.6 and earlier, where the clientid parameter lacks proper input sanitization, allowing low-privileged authenticated users to inject malicious SQL queries.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Revive Adserver installationCheck for Revive Adserver by looking for its admin interface at /admin/ or by searching for characteristic files like lib.inc.php in the web root.Affected if Revive Adserver is not installed on the system.
-
Determine installed versionCheck the version file typically located at lib/version.inc.php or look for a version identifier in the admin dashboard under System Information or About section.Affected if The installed version is 6.0.6 or earlier.
-
Confirm zone-include.php existsLocate the zone-include.php file in the web root directory (commonly in the root or www/ folder of the Revive Adserver installation).Affected if The file exists and is accessible via the web server.
-
Check clientid parameter handlingReview zone-include.php source code and search for the clientid parameter usage; verify if it is directly used in SQL queries without proper sanitization or parameterized queries.Affected if The clientid parameter is processed without input validation or prepared statements.
A user is affected if they run Revive Adserver version 6.0.6 or earlier with the zone-include.php file accessible and the clientid parameter used in SQL queries without sanitization.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to Revive Adserver version 6.0.7 or later where input sanitisation has been implemented; verify the patch is applied and conduct penetration testing to confirm the SQL injection is no longer exploitable.
