Improper Neutralization of Special Elements used in a Command ('Command Injection')
Concrete CMS (formerly concrete5) versions prior to 8.5.10, and 9.0.x prior to 9.1.3 is vulnerable to Stored Cross-Site Scripting (XSS) in "dashboard/system/express/entities/associations" because Concrete CMS allows association with an entity name that doesn’t exist or, if it does exist, contains XSS since it was not properly sanitized. Remediate by updating to Concrete CMS 9.1.3 or 8.5.10.
CWE-77 - Command Injection
A command injection attack involves injecting an operating system command through the data input, which gets executed on the host operating system with the privileges of the victimized application. The impact of a command injection attack may range from loss of data confidentiality and integrity to unauthorized remote access to the hosting system. The attack may cause serious data breaches and system takeover.
