Many critical security flaws have been disclosed in Samsung’s pre-set up Android applications, which, if effectively exploited, could have permitted adversaries entry to personalized data with no users’ consent and just take control of the equipment.
“The impression of these bugs could have permitted an attacker to access and edit the victim’s contacts, phone calls, SMS/MMS, set up arbitrary applications with system administrator rights, or study and compose arbitrary data files on behalf of a procedure user which could transform the device’s configurations,” Sergey Toshin, founder of mobile security startup Oversecured, explained in an examination printed Thursday.

Toshin documented the flaws to Samsung in February 2021, pursuing which patches have been issued by the maker as element of its every month security updates for April and May perhaps. The record of the 7 vulnerabilities is as follows –
- CVE-2021-25356 – third-party authentication bypass in Managed Provisioning
- CVE-2021-25388 – Arbitrary app set up vulnerability in Knox Core
- CVE-2021-25390 – Intent redirection in PhotoTable
- CVE-2021-25391 – Intent redirection in Protected Folder
- CVE-2021-25392 – Feasible to access notification plan file of DeX
- CVE-2021-25393 – Possible to study/write accessibility to arbitrary information as a technique consumer (has an effect on the Configurations app)
- CVE-2021-25397 – Arbitrary file publish in TelephonyUI
The impact of these flaws signifies they could be exploited to install arbitrary 3rd-party apps, grant the gadget admin privileges to delete other set up applications or steal delicate data files, browse or compose arbitrary information as a process consumer, and even execute privileged actions.
In a evidence-of-concept (PoC) demo, Oversecured set up that it was achievable to leverage the intent redirection flaws in PhotoTable and Secure Folder to hijack the apps’ permissions to obtain the SD card and read through contacts saved in the phone. Likewise, by exploiting CVE-2021-25397 and CVE-2021-25392, an attacker could overwrite the file storing SMS/MMS messages with destructive material and steal info from person notifications.
Samsung machine homeowners are proposed to use the newest firmware updates from the company to stay clear of any likely security hazards.
