Zimperium firm released the Android Stagefright Exploit Code, the Android flaw that is threatening the users of the popular Google mobile OS.
Experts at Zimperium Mobile Security Labs (zLabs) recently discovered a critical flaw, dubbed Stagefright affecting the Android OS.
The experts revealed that the Stagefright flaw (CVE-2015-1538) potentially affects 95% of Android devices running version 2.2 to 5.1 of the Google OS (roughly 950 million smartphones). The Zimperium firm consider the Stagefright vulnerability as the worst Android flaw in the mobile OS history, the vulnerability affects a media library app that is used for by Android to process Stagefright media files. According to the experts at Zimperium the media library is affected by several vulnerabilities.
The researchers implemented the Stagefright Exploit in python by creating an MP4 exploiting the ‘stsc’ vulnerability, aka Stagefright vulnerability.
“We are pleased to finally make this code available to the general public so that security teams, administrators, and penetration testers alike may test whether or not systems remain vulnerable. What follows is a python script that generates an MP4 exploiting the ‘stsc’ vulnerability otherwise known as CVE-2015-1538 (#1).” states Zimperium.
The experts released the Stagefright exploits to allow security experts to examine their systems against this vulnerability.
According to the US-CERT/CC advisory, the Android Stagefright contains multiple vulnerabilities including:
CVE-2015-1538, P0006, Google Stagefright ‘stsc’ MP4 Atom Integer Overflow Remote Code Execution
CVE-2015-1538, P0004, Google Stagefright ‘ctts’ MP4 Atom Integer Overflow Remote Code Execution
