High 8.8
In plain English
A high-severity code injection in Adserver from Revive. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.6% (higher than 48% of all known vulnerabilities).
Official description
A missing validation of user input exists when saving delivery limitations in Revive Adserver 6.0.6 and earlier. A low‑privileged user could add an unexpected component parameter and inject malicious PHP code into the compiledlimitations field, which would then be executed during banner delivery. Input sanitisation has been improved to ensure that unexpected parameters are filtered out.
