Advisory by Netsparker  
Name: XSS Vulnerability in Serendipity  
Affected Software : Serendipity  
Affected Versions: v2.0.2 and possibly below  
Vendor Homepage :  
Vulnerability Type : Cross-site Scripting  
Severity : Important  
Status : Fixed  
CVE-ID : CVE-2015-8603  
Netsparker Advisory Reference : NS-15-024  
By exploiting a Cross-site scripting vulnerability the attacker can  
hijack a logged in user’s session. This means that the malicious  
hacker can change the logged in user’s password and invalidate the  
session of the victim while the hacker maintains access. As seen from  
the XSS example in this article, if a web application is vulnerable to  
cross-site scripting and the administrator’s session is hijacked, the  
malicious hacker exploiting the vulnerability will have full admin  
privileges on that web application.
