Facebooks Android app that could be exploited to launch remote code execution (RCE) attacks

Greeting Everyone! Hope Everything is going well and good recently A security researcher has found a vulnerability issue in Facebooks Android app in their download features which advanage fir an attacker that could be exploited to launch remote code execution (RCE) attacks. And For finding this critical issue researcher awarded the researcher $10,000 for finding the bug.

What is rce?

Rce Contain remote code execution arbitrary code execution is an attacker’s ability to execute arbitrary commands or code on a target machine which interpreter with system. RCE is critical Vulnerability which has huge impact.

As according To facebook application in their android app which contain two methods when downloading file from group a built in Android service called first Download Manager and a second method called Files Tab. As researcher Sayed Abdelhafiz verified a path traversal flaw in mehod second Called Files Tab.

“I discovered an ACE on Facebook for Android that can be triaged through a download file from group Files Tab without opening the file,” he said in a post on Medium.

The vulnerability was in the second method. While security measures were implemented on the server-side when uploading the files, it was easy to bypass those.

“The first idea that came to my mind was to use path traversal to overwrite native libraries which will lead to executing arbitrary code,” Abdelhafiz said.

Abdelhafiz explained how the Files Tab flaw enabled the researcher to launch RCE attacks against a target device.

The vulnerability in the Files Tab has now been fixed.

The Facebook Android app vulnerability refers to a security flaw in Facebook’s mobile application for Android devices. This flaw could potentially be exploited by attackers to launch Remote Code Execution (RCE) attacks, gaining unauthorized control over a user’s device.


RCE is a type of cyber attack where an attacker can execute malicious code on a victim’s device remotely, often leading to complete control or compromise of the device’s functionalities.


Users with the Facebook Android app installed on their devices could be at risk if the vulnerability is exploited. Attackers could potentially take control of the app and, in some cases, gain access to sensitive data or compromise the device.


It is essential to check for updates from Facebook regarding this vulnerability. Software developers typically release patches and updates to address such security issues.

To mitigate the risk, ensure that your Facebook app is up to date by regularly installing the latest updates. Additionally, consider using strong, unique passwords and enabling two-factor authentication on your Facebook account.

While the specific risk to personal data depends on the severity of the exploitation, it’s crucial to stay informed about the situation, follow best security practices, and monitor your account for any unusual activity.


For the most accurate and up-to-date information, refer to official statements from Facebook or cybersecurity experts who are actively tracking this issue. Stay informed to take appropriate action to protect your device and data.
