Report-Timeline: ================ 2013-08-03: Public Disclosure (Vulnerability Laboratory) Status: ======== Published Affected Products: ================== Apple AppStore Product: withU - Music Share Application 1.3.7 Exploitation-Technique: ======================= Local Severity: ========= High Details: ======== A local command/path injection web vulnerability is detected in the withU v1.3.7 Music-Share application (Apple iOS - iPad & iPhone). The vulnerability allows to inject local commands via vulnerable system values to compromise the apple mobile iOS application. The vulnerability is located in the index file dir (header) listing module when processing to request and list the ipad or iphone devicename. Local attackers can change the name of the device to inject the code and request any local path or inject commands on application-side. The malicious context with the path request executes when an user or victim is watching the file dir index listing. Exploitation of the web vulnerability requires a local privilege iOS device account with restricted access and no user interaction. Successful exploitation of the vulnerability results unauthorized execution of system specific commands and path requests.
