Mô tả CVE

An issue was discovered in a third-party com.factory.mmigroup component, shipped on devices from multiple device manufacturers. Certain software builds for various Android devices contain a vulnerable pre-installed app with a package name of com.factory.mmigroup (versionCode='3', versionName='2.1) that allows local third-party apps to perform various actions, due to inadequate access control, in its context (system user), but the functionalities exposed depend on the specific device. The following capabilities are exposed to zero-permission, third-party apps on the following devices: arbitrary AT command execution via AT command injection (T-Mobile Revvl 6 Pro 5G, T-Mobile Revvl V+ 5G, and Boost Mobile Celero 5G); programmatic factory reset (Samsung Galaxy A03S, T-Mobile Revvl 6 Pro 5G, T-Mobile Revvl V+ 5G, Boost Mobile Celero, Realme C25Y, and Lenovo Tab M8 HD), leaking IMEI (Samsung Galaxy A03S, T-Mobile Revvl 6 Pro 5G, T-Mobile Revvl V+ 5G, Boost Mobile Celero, and Realme C25Y); leaking serial number (Samsung Galaxy A03s, T-Mobile Revvl 6 Pro 5G, T-Mobile Revvl V+ 5G, Boost Mobile Celero, Realme C25Y, and Lenovo Tab M8 HD); powering off the device (Realme C25Y, Samsung Galaxy A03S, and T-Mobile Revvl 6 Pro 5G); and programmatically enabling/disabling airplane mode (Samsung Galaxy A03S, T-Mobile Revvl 6 Pro 5G, T-Mobile Revvl V+ 5G, Boost Mobile Celero, and Realme C25Y); and enabling Wi-Fi, Bluetooth, and GPS (Samsung Galaxy A03S, T-Mobile Revvl 6 Pro 5G, T-Mobile Revvl V+ 5G, Boost Mobile Celero, and Realme C25Y). No permissions or special privileges are necessary to exploit the vulnerabilities in the com.factory.mmigroup app. No user interaction is required beyond installing and running a third-party app. The software build fingerprints for each confirmed vulnerable device are as follows: Boost Mobile Celero 5G (Celero5G/Jupiter/Jupiter:11/RP1A.200720.011/SW_S98119AA1_V067:user/release-keys, Celero5G/Jupiter/Jupiter:11/RP1A.200720.011/SW_S98119AA1_V064:user/release-keys, Celero5G/Jupiter/Jupiter:11/RP1A.200720.011/SW_S98119AA1_V061:user/release-keys, and Celero5G/Jupiter/Jupiter:11/RP1A.200720.011/SW_S98119AA1_V052:user/release-keys); Samsung Galaxy A03S (samsung/a03sutfn/a03su:13/TP1A.220624.014/S134DLUDU6CWB6:user/release-keys and samsung/a03sutfn/a03su:12/SP1A.210812.016/S134DLUDS5BWA1:user/release-keys); Lenovo Tab M8 HD (Lenovo/LenovoTB-8505F/8505F:10/QP1A.190711.020/S300637_220706_BMP:user/release-keys and Lenovo/LenovoTB-8505F/8505F:10/QP1A.190711.020/S300448_220114_BMP:user/release-keys); T-Mobile Revvl 6 Pro 5G (T-Mobile/Augusta/Augusta:12/SP1A.210812.016/SW_S98121AA1_V070:user/release-keys and T-Mobile/Augusta/Augusta:12/SP1A.210812.016/SW_S98121AA1_V066:user/release-keys); T-Mobile Revvl V+ 5G (T-Mobile/Sprout/Sprout:11/RP1A.200720.011/SW_S98115AA1_V077:user/release-keys and T-Mobile/Sprout/Sprout:11/RP1A.200720.011/SW_S98115AA1_V060:user/release-keys); and Realme C25Y (realme/RMX3269/RED8F6:11/RP1A.201005.001/1675861640000:user/release-keys, realme/RMX3269/RED8F6:11/RP1A.201005.001/1664031768000:user/release-keys, realme/RMX3269/RED8F6:11/RP1A.201005.001/1652814687000:user/release-keys, and realme/RMX3269/RED8F6:11/RP1A.201005.001/1635785712000:user/release-keys). This malicious app sends a broadcast Intent to com.factory.mmigroup/.MMIGroupReceiver. This causes the com.factory.mmigroup app to dynamically register for various action strings. The malicious app can then send these strings, allowing it to perform various behaviors that the com.factory.mmigroup app exposes. The actual behaviors exposed by the com.factory.mmigroup app depend on device model and chipset. The com.factory.mmigroup app executes as the "system" user, allowing it to interact with the baseband processor and perform various other sensitive actions.

Base: Exploitabilty Metrics

The Exploitability metrics reflect the characteristics of the thing that is vulnerable, which we refer to formally as the vulnerable component.

Attack Vector

This metric reflects the context by which vulnerability exploitation is possible.

Local

The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities.

Attack Complexity

This metric describes the conditions beyond the attacker’s control that must exist in order to exploit the vulnerability.

Low

Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success when attacking the vulnerable component.

Privileges Required

This metric describes the level of privileges an attacker must possess before successfully exploiting the vulnerability.

None

The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.

User Interaction

This metric captures the requirement for a human user, other than the attacker, to participate in the successful compromise of the vulnerable component.

None

The vulnerable system can be exploited without interaction from any user.

Base: Scope Metrics

The Scope metric captures whether a vulnerability in one vulnerable component impacts resources in components beyond its security scope.

Scope

Formally, a security authority is a mechanism (e.g., an application, an operating system, firmware, a sandbox environment) that defines and enforces access control in terms of how certain subjects/actors (e.g., human users, processes) can access certain restricted objects/resources (e.g., files, CPU, memory) in a controlled manner. All the subjects and objects under the jurisdiction of a single security authority are considered to be under one security scope. If a vulnerability in a vulnerable component can affect a component which is in a different security scope than the vulnerable component, a Scope change occurs. Intuitively, whenever the impact of a vulnerability breaches a security/trust boundary and impacts components outside the security scope in which vulnerable component resides, a Scope change occurs.

Unchanged

An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.

Base: Impact Metrics

The Impact metrics capture the effects of a successfully exploited vulnerability on the component that suffers the worst outcome that is most directly and predictably associated with the attack. Analysts should constrain impacts to a reasonable, final outcome which they are confident an attacker is able to achieve.

Confidentiality Impact

This metric measures the impact to the confidentiality of the information resources managed by a software component due to a successfully exploited vulnerability.

High

There is a total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact. For example, an attacker steals the administrator's password, or private encryption keys of a web server.

Integrity Impact

This metric measures the impact to integrity of a successfully exploited vulnerability. Integrity refers to the trustworthiness and veracity of information.

High

There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.

Availability Impact

This metric measures the impact to the availability of the impacted component resulting from a successfully exploited vulnerability.

High

There is a total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Temporal Metrics

The Temporal metrics measure the current state of exploit techniques or code availability, the existence of any patches or workarounds, or the confidence in the description of a vulnerability.

Environmental Metrics

These metrics enable the analyst to customize the CVSS score depending on the importance of the affected IT asset to a user’s organization, measured in terms of Confidentiality, Integrity, and Availability.

EPSS

EPSS là mô hình tính điểm dự đoán khả năng một lỗ hổng bị khai thác.

Điểm EPSS

Mô hình EPSS tạo ra điểm xác suất từ 0 đến 1 (0 đến 100%). Điểm càng cao, xác suất một lỗ hổng bị khai thác càng lớn.

Phân vị EPSS

Phân vị được dùng để xếp hạng CVE theo điểm EPSS. Ví dụ, một CVE ở phân vị thứ 95 theo điểm EPSS có nhiều khả năng bị khai thác hơn 95% CVE khác. Do đó, phân vị được dùng để so sánh điểm EPSS của một CVE với các CVE khác.
