Description
A missing validation of user input when saving delivery limitations in Revive Adserver 6.0.6 and earlier could allow a low‑privileged user to use the logical parameter to inject malicious PHP code into the compiledlimitations field on the database and have it executed during banner delivery. Input sanitisation has been improved to ensure that the parameter is properly validated.
