• AV:L (Local Access Vector): The attacker needs local access to the device.
• AC:L (Low Attack Complexity): The attack is straightforward and does not require specialized conditions.
• AT:N (No Authentication Required): No authentication is needed to exploit the vulnerability.
• PR:N (No Privileges Required): No special privileges are required.
• UI:N (No User Interaction Required): No user interaction is necessary for the attack to succeed.
• VC:H (High Confidentiality Impact): The vulnerability can lead to a significant loss of confidentiality.
• VI:H (High Integrity Impact): The vulnerability can lead to a significant loss of integrity.
• VA:H (High Availability Impact): The vulnerability can lead to a significant loss of availability.
• SC:H (High Scope Change): The vulnerability affects components beyond its security scope.
• SI:H (High Integrity Impact): The vulnerability can lead to a significant loss of integrity.
• SA:H (High Availability Impact): The vulnerability can lead to a significant loss of availability.
• S:N (No Scope Change): The vulnerability does not change the security scope.
• R:I (Integrity Impact): The vulnerability has a high impact on integrity.
• V:D (Disclosure Vector): The vulnerability details are publicly disclosed.
• U:Amber (Uncertainty Level): The uncertainty level is amber, indicating some level of uncertainty.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Local Access: An attacker with physical access to the device can exploit the vulnerability.
• Malicious Applications: An attacker could develop a malicious application that, once installed, exploits the unsecured broadcast receiver to trigger a factory reset.

Exploitation Methods:

• Direct Communication: The attacker can send a crafted broadcast message to the receiver, forcing the device to perform a factory reset.
• Malware Distribution: Distributing malware through unofficial app stores or social engineering tactics to trick users into installing the malicious application.

3. Affected Systems and Software Versions

The vulnerability is presumed to affect all Infinix Mobile devices, particularly those running the "com.transsion.agingfunction" application version 13. Given the lack of vendor response, it is reasonable to assume that a wide range of Infinix devices are at risk.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Disable the Application: Users should disable the "com.transsion.agingfunction" application if possible.
• Limit Physical Access: Ensure that devices are not left unattended in public places.
• Avoid Untrusted Apps: Users should avoid installing applications from untrusted sources.

Long-Term Mitigation:

• Vendor Patch: Infinix Mobile should release a security patch to secure the broadcast receiver.
• Regular Updates: Users should regularly update their devices to ensure they have the latest security patches.
• Security Awareness: Educate users about the risks of installing applications from untrusted sources and the importance of device security.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to the European cybersecurity landscape, particularly given the widespread use of Infinix devices. The ability to perform a factory reset without permissions can lead to data loss, unauthorized access, and potential breaches of personal and corporate information. This underscores the need for robust security measures and timely vendor responses to vulnerabilities.

6. Technical Details for Security Professionals

Broadcast Receiver Vulnerability:

• The "com.transsion.agingfunction" application exposes a broadcast receiver that listens for specific intents.
• The receiver does not implement proper security checks, allowing any application to send intents that trigger a factory reset.

Detection and Monitoring:

• Log Analysis: Monitor device logs for unusual broadcast intents related to factory resets.
• Behavioral Analysis: Implement behavioral analysis tools to detect and block suspicious activities related to broadcast intents.

Incident Response:

• Containment: Isolate affected devices and prevent further unauthorized access.
• Eradication: Remove any malicious applications and secure the broadcast receiver.
• Recovery: Restore devices from backups if necessary and apply security patches.

Preventive Measures:

• Code Review: Conduct thorough code reviews to identify and mitigate similar vulnerabilities in other applications.
• Security Testing: Implement regular security testing, including static and dynamic analysis, to detect and fix vulnerabilities.

In conclusion, the vulnerability described in EUVD-2024-33513 is critical and requires immediate attention from both users and the vendor. Effective mitigation strategies and proactive security measures are essential to protect against potential exploits and maintain the integrity of the European cybersecurity landscape.
