CVE-2017-15997
Because there is a static RC4 key, an attacker can gain access to user credentials more easily by leveraging access to the preferences XML file.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.13%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In the "NQ Contacts Backup & Restore" application 1.1 for Android, RC4 encryption is used to secure the user password locally stored in shared preferences. Because there is a static RC4 key, an attacker can gain access to user credentials more easily by leveraging access to the preferences XML file.
