Product: PSN Community - Lithium Forums 2012 Q4  
A persistent web vulnerability is detected in Sony`s official PSN Community Website Application.  
The vulnerability allows remote attackers to send own malicious persistent script code as notification   
message to hijack or phish psn application user accounts.  
The vulnerability in the psn community (forum) is located in the outgoing mail parse of the   
private message notification with the bound vulnerable username parameter. The script code will be   
executed when the attacker injects script code as username. In the application and software itself   
the web context is parsed but not in the outgoing notification mail of the community when a message   
has been send or arrives.  
Vulnerable Section(s):  
[+] PSN Community - Forums [Private Messages]  
Vulnerable Module(s):  
[+] Forums [Private Messages] - Notification Mail (Active Message Notification)  
Vulnerable Module(s):  
[+] Username  
Proof of Concept:  
The persistent vulnerability can be exploited by remote attackers with low privilege community application   
account with low or medium required user inter action. For demonstration or reproduce ...  
1. Register a username with a test iframe inside  
2. Activate the checkbox with the private message notification mail  
3. Send yourself a message with any random content  
4. Open the notification mail and watch the username web context  
5. Reproduce successful! The script code will be executed out of the notification mail of the private messages
