Vulnerability Disclosure Timeline: ================================== 2016-02-17: Researcher Notification & Coordination (Benjamin Kunz Mejri - Evolution Security GmbH) 2016-02-18: Vendor Notification (BMW Security Team) 2016-04-02: Vendor Response/Feedback (BMW Security Team) 2016-07-06: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Affected Product(s): ==================== Exploitation Technique: ======================= Remote Severity Level: =============== Medium Technical Details & Description: ================================ A client-side cross site scripting web vulnerability has been discovered in the official BMW online service web-application. The vulnerability allows remote attacker to inject own malicious script codes to the client-side of the affected module context. The vulnerability is located in the `t` value (token) of the `passwordResetOk.html` web-application file. Remote attackers are able to inject own client-side script codes to the `passwordResetOk.html` file. the request method to inject is GET and the vulnerability is located on the client-side of the affected bmw web-service. The attacker injects the payload after the secure token to execute the context in the passwordResetOk.html file. The vulnerability is a classic client-side cross site scripting web vulnerability. The security risk of the non-persistent vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 3.6. Exploitation of the persistent input validation web vulnerability requires no privileged web-application user account and low user interaction. Successful exploitation of the vulnerability results in session hijacking, non-persistent phishing, non-persistent external redirects to malicious source and non-persistent manipulation of affected or connected application modules. Request Method(s): [+] GET Vulnerable Module(s): [+] ./de/publicPools/landingPages/ Vulnerable File(s): [+] passwordResetOk.html Vulnerable Parameter(s): [+] t (token) Affected Module(s): [+] Password Reset Function Proof of Concept (PoC): ======================= The client-side cross site scripting web vulnerability can be exploited by remote attackers without privileged web-application user account and with low user interaction (click|link).
