Document Title: =============== Remote Desktop v0.9.4 Android - Multiple Vulnerabilities References (Source): ==================== http://ift.tt/1C9ELzn Release Date: ============= 2015-01-20 Vulnerability Laboratory ID (VL-ID): ==================================== 1413 Common Vulnerability Scoring System: ==================================== 4.4 Product & Service Introduction: =============================== Remote Desktop brings order to your Droid. View and retrieve all the contents of your phone such as documents, photos, videos. All you need is a standard web browser (! the latest Chrome or Firefox !) and Remote Desktop will allow you interact with your phone as easily as a PC. (Copy of the Homepage: http://ift.tt/1BdFrCj & http://ift.tt/1iCTzyg ) Abstract Advisory Information: ============================== An independent vulnerability laboratory researcher discovered multiple web vulnerabilities in the Remote Desktop v0.9.4 Android mobile web-application. Vulnerability Disclosure Timeline: ================================== 2015-01-20: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Affected Product(s): ==================== Damian Kolakowski Product: Remote Desktop - Android Mobile Web Application 0.9.4 Exploitation Technique: ======================= Remote Severity Level: =============== Medium Technical Details & Description: ================================ Multiple vulnerabilities has been discovered in the Remote Desktop v0.9.4 Android mobile web-application. The mobile web-application is vulnerable to a combination of cross site request forgery and local command injection attacks. 1.1 The local command injection vulnerability is located in `cmd` value of the `/api/sms` file. The remote attackers performs a client-side request and manipulates the `cmd` value to compromise the web-app by a local command injection. The security risk of the local command/path inject vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 5.5. Exploitation of the command/path inject vulnerability requires no privileged android device user account or user interaction. Successful exploitation of the vulnerability results in unauthorized execution of system specific commands and unauthorized path value requests to compromise the mobile android application and the connected device. Request Method(s): [+] [GET] Vulnerable Module(s): [+] /api/sms Vulnerable Parameter(s): [+] cmd=%3Cform%20action=api/[x]?cmd= 1.2 The cross site request forgery vulnerabilities are located in the `shell`,`sms`,`calllogs` and `files` sections of the android app. Remote attackers are able prepare special crafted URLs that executes client-side requests to execute application functions (delete,add, call, send). The requst method to execute a function in a client-side request is GET. The security risk of the client-side web vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 2.4. Exploitation of the client-side web vulnerability requires no privileged web-application user account but medium or high user interaction. Successful exploitation of the vulnerabilities result in non-persistent phishing mails, session hijacking, non-persistent external redirect to malicious sources and client-side manipulation of affected or connected module context. Request Method(s): [+] [GET] Vulnerable Parameter(s): [+] shell [+] sms [+] calllogs Proof of Concept (PoC): ======================= The vulnerabilities can be exploited by remote attackers without privileged application user account and with low or medium user interaction.
