Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')


Severity High
Score 8.8/10


The RESTful Web Services (restws) module 7.x-1.x before 7.x-1.4 and 7.x-2.x before 7.x-2.1 for Drupal does not properly restrict access to entity write operations, which makes it easier for remote authenticated users with the "access resource node" and "create page content" permissions (or equivalents) to conduct cross-site scripting (XSS) or execute arbitrary PHP code via a crafted text field.

CWE-79 - Cross Site Scripting

Cross-Site Scripting, commonly referred to as XSS, is the most dominant class of vulnerabilities. It allows an attacker to inject malicious code into a pregnable web application and victimize its users. The exploitation of such a weakness can cause severe issues such as account takeover, and sensitive data exfiltration. Because of the prevalence of XSS vulnerabilities and their high rate of exploitation, it has remained in the OWASP top 10 vulnerabilities for years.
