FAUCET Score

CVE-2015-5515 describes a vulnerability in the Drupal Views Bulk Operations (VBO) module (versions 6.x-1.x and 7.x-3.x before 7.x-3.3). This flaw allows authenticated users with access to a VBO-enabled user account listing view to arbitrarily edit user accounts and assign roles if the "change roles" bulk operation is enabled. The vulnerability has a CVSS score of 4.9, indicating a medium severity. It requires authentication (Au:S) and medium attack complexity (AC:M), but can be exploited remotely (AV:N) to impact integrity and availability (I:P/A:P) by modifying user roles. There is no evidence of active exploitation, and no public exploit code is available in Metasploit, Nuclei, or ExploitDB. Community discussion and media coverage for this CVE are minimal, suggesting low public awareness and attention.
