Revive Adserver PHP Code Injection via Delivery Limitations

Publication date: 2026-06-23

Last updated on: 2026-06-23

Assigner: HackerOne

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.

Executive Summary

This vulnerability exists in Revive Adserver version 6.0.6 and earlier, where there is a missing validation of user input when saving delivery limitations. A low-privileged user can exploit this by injecting malicious PHP code through the logical parameter into the compiledlimitations field in the database. This malicious code can then be executed during banner delivery.

The issue arises because input sanitisation was insufficient, allowing unsafe data to be stored and executed. The vulnerability has been addressed by improving input validation to ensure the parameter is properly checked.

Impact Analysis

Exploitation of this vulnerability can lead to remote code execution with the privileges of the application, allowing an attacker to run arbitrary PHP code on the server.

  • Compromise of the server hosting Revive Adserver.
  • Potential data theft or manipulation.
  • Disruption of banner delivery services.
  • Full system compromise depending on server configuration.
Mitigation Strategies

To mitigate this vulnerability, ensure that you upgrade Revive Adserver to a version later than 6.0.6 where input sanitisation has been improved to properly validate the logical parameter.

Additionally, restrict low-privileged users from modifying delivery limitations until the update is applied.
