The Computer Emergency Response Team of India (CERT-In), on behalf of the Indian government, has issued a high-risk warning to Samsung mobile phone users regarding several vulnerabilities. The warning, known as CERT-In Vulnerability Note CIVN-2023-0360, emphasizes the critical security issues that affect Samsung Mobile Android versions 11, 12, 13, and 14. These vulnerabilities have been classified as HIGH due to their potential impact and the ease with which they can be exploited.
Researchers at CERT-In have identified multiple vulnerabilities in Samsung products that pose significant threats. These vulnerabilities have the potential to bypass security restrictions, gain unauthorized access to sensitive information, and execute arbitrary code on targeted systems. The vulnerabilities are diverse and affect various components of the Samsung ecosystem, as outlined in the CERT-In advisory.
According to CERT-In, the vulnerabilities identified in Samsung products are a result of various issues, including improper access control in Knox features, an integer overflow flaw in facial recognition software, authorization issues with the AR Emoji app, incorrect handling of errors in Knox security software, multiple memory corruption vulnerabilities in various system components, incorrect data size verification in the softsimd library, unvalidated user input in the Smart Clip app, and hijacking of certain app interactions in contacts.
The successful exploitation of these vulnerabilities could have severe consequences. It may allow an attacker to trigger heap overflow and stack-based buffer overflow, access the device SIM PIN, send broadcasts with elevated privilege, read sandbox data of AR Emoji, bypass Knox Guard lock by changing system time, access arbitrary files, gain access to sensitive information, execute arbitrary code, and compromise the targeted system, as stated in the security note.
The latest vulnerabilities affect Samsung Mobile Android versions 11, 12, 13, and 14, putting a wide range of Samsung devices at risk. This includes the Galaxy S23 series, Galaxy Flip 5, Galaxy Fold 5, and other Samsung devices.
To protect your phone from these vulnerabilities, it is strongly advised to take the following actions:
- Apply Security Updates: Promptly apply the security updates provided by Samsung in their official security advisory. You can check for updates on your device by going to Settings > Software update > Download and install. Additionally, regularly check for updates and install them to ensure the latest security patches are applied.
- Exercise Caution: Until the update is applied, exercise caution while using the affected devices, especially when interacting with untrusted sources or unknown applications.
- Ensure your applications are always updated: Outdated applications may possess vulnerabilities that attackers can take advantage of. It is crucial to regularly check for updates by visiting the Google Play Store.
- Exercise caution while installing applications: It is recommended to solely install applications from reliable sources, such as the Google Play Store. Avoid downloading applications from third-party websites as they may contain malicious content.
- Exercise vigilance when clicking on links: Refrain from clicking on links in emails or messages sent by unfamiliar senders. These links may redirect you to phishing websites that aim to steal your personal information.
