Type:local
Threat Level:
3/10
Description:Unsafe environment variables and file descriptors usage
Affected:CHAINSDD : ChainsDD Superuser 3.1
 CHAINFIRE : Chainfire SuperSU 1.68
CVE:CVE-2013-6775 (The Chainfire SuperSU package before 1.69 for Android allows attackers to gain privileges via the (1) backtick or (2) $() type of shell metacharacters in the -c option to /system/xbin/su.)
 CVE-2013-6774 (Untrusted search path vulnerability in the ChainsDD Superuser package 3.1.3 for Android 4.2.x and earlier, CyanogenMod/ClockWorkMod/Koush Superuser package 1.0.2.1 for Android 4.2.x and earlier, and Chainfire SuperSU package before 1.69 for Android 4.2.x and earlier allows attackers to load an arbitrary .jar file and gain privileges via a crafted BOOTCLASSPATH environment variable for a /system/xbin/su process. NOTE: another researcher was unable to reproduce this with ChainsDD Superuser.)
 CVE-2013-6770 (The CyanogenMod/ClockWorkMod/Koush Superuser package 1.0.2.1 for Android 4.3 and 4.4 does not properly restrict the set of users who can execute /system/xbin/su with the --daemon option, which allows attackers to gain privileges by leveraging ADB shell access and a certain Linux UID, and then creating a Trojan horse script.)
 CVE-2013-6768 (Untrusted search path vulnerability in the CyanogenMod/ClockWorkMod/Koush Superuser package 1.0.2.1 for Android 4.2.x and earlier allows attackers to trigger the launch of a Trojan horse app_process program via a crafted PATH environment variable for a /system/xbin/su process.)
