IMPACT The research company Procheckup who worked with Juniper to resolve this issue describes the vulnerability as: "There is multiple authenticated Cross-site Scripting vulnerability on Junipers, IVE web interface. Procheckup has found by making a malformed authenticated request to the IVE Web interface, that vanilla cross site scripting (XSS) attacks are possible. ... An attacker may be able to cause execution of malicious scripting code in the browser of a user who clicks on a link or visits a malicious webpage. The malicious code would run in the security context of the vulnerable website. This type of attack can result in non-persistent defacement of the target site, or the redirection of confidential information (i.e.: passwords or session IDs) to unauthorised third parties." [1] MITIGATION It is recommended the users of the Juniper Secure Access series (Juniper IVE) devices update to version 6.5R3.1 (build 15255) or a later version.[2] Juniper has provided information regarding this issue to its customers on its members only website.
