New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 8.3


A PHP application running on the remote web server is affected by a remote code execution vulnerability.


According to its self-reported version, the instance of Drupal running on the remote web server is 7.x prior to 7.74, 8.x prior to 8.8.11, 8.9.x prior to 8.9.9, or 9.0.x prior to 9.0.8. It is, therefore, affected by a remote code execution vulnerability in its file upload functionality due to a failure to sanitize filenames. An authenticated, remote attacker can exploit this to execute arbitrary php code under certain hosting configurations.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Upgrade to Drupal version 7.74 / 8.8.11 / 8.9.9 / 9.0.8 or later.
