Vulnerability Disclosure Timeline: ================================== 2012-10-03: Public Disclosure Discovery Status: ================= Published Affected Product(s): ==================== OlimSoft Product: OPlayer - iPhone,iPod Touch & iPad 2.0.05 Exploitation Technique: ======================= Remote Severity Level: =============== Medium Technical Details & Description: ================================ Multiple persistent web vulnerabilities are detected in the OPlayer application v2.0.05 for Apples iPhones, iPod Touche & iPads. The vulnerability allows an attacker (remote) to inject own malicious persistent script code to compromise the affected mobile application. The first web vulnerability is located in the OPlayer WIFI Transfer application module in the create/rename folder function with the bound vulnerable folder name parameter. Attackers can inject own malicious script code or malware as foldername. The script code will be executed out of the main application name listing web context. The second vulnerability is located in the OPlayer WIFI Transfer application module when processing to delete a script code tag as foldername. The mobile device application itself ask when processing to delete a malicious injected script code as foldername. The application did not parse the request when processing to display the ask to confirm delete messagebox. Attackers can use the not parsed +filename function to execute malicious persistent script code out of the ask to confirm messagebox when processing to delete a folder. The vulnerability can be exploited by remote attackers without privileged user account & with low or medium user inter action. Successful exploitation of the vulnerability result in application compromise via persistent injects, information disclosure (local files), persistent malware loads or persistent web context request manipulation. The wifi application needs to be activated because of the remote available http interface to upload music for oplayer. The service itself allows to inject remotly without using any permission change or password.

Review: Ask to Confirm - Delete Message Solution - Fix & Patch: ======================= The vulnerability can be patched by parsing the app and interface foldername input mask and output listing. The second vulnerability can be patched by parsing the displayed web context in the ask to confirm question. The input fields should be restricted with the following useful input characters [a-z][A-Z][0-9]. Security Risk: ============== The security risk of the persistent input validation vulnerabilities are estimated as medium(+) Credits & Authors: ================== Vulnerability Laboratory [Research Team] - Benjamin Kunz Mejri (bkm@vulnerability-lab.com) Disclaimer & Information: ========================= The information provided in this advisory is provided as it is without any warranty.
