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


Severity Low
Score 3.5/10


Cross-site scripting (XSS) vulnerability in the administration panel in bBlog 0.7.2 allows remote authenticated users with superuser privileges to inject arbitrary web script or HTML via a blog name ($blogname). NOTE: if administrators are normally allowed to add HTML by other means, e.g. through Smarty templates, then this issue would not give any additional privileges, and thus would not be considered a vulnerability.

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.
