High · published January 18, 2021
CVSS calls it high at 7.5. It is confirmed in active exploitation. It sits in the 99.4th percentile for exploit probability.
🚨 A sneaky directory traversal in Archive_Tar could let an attacker write anywhere they want — think of it as a delivery driver who doesn’t check the address before dropping off packages! ⚡ Imagine a restaurant that allows servers to deliver food without checking the order tickets first. If a server takes the wrong order without verification, it can lead to chaos in the kitchen, just like this vulnerability allows unauthorized writes to critical files. An attacker could exploit this vulnerability to write malicious files anywhere on the server, potentially leading to complete system compromise. This is absolutely devastating, as it can allow the installation of backdoors or even the destruction of sensitive data.
Imagine a restaurant that allows servers to deliver food without checking the order tickets first. If a server takes the wrong order without verification, it can lead to chaos in the kitchen, just like this vulnerability allows unauthorized writes to critical files. This vulnerability in Archive_Tar allows directory traversal when handling symbolic links, enabling write operations to arbitrary directories without proper validation.
An attacker could exploit this vulnerability to write malicious files anywhere on the server, potentially leading to complete system compromise. This is absolutely devastating, as it can allow the installation of backdoors or even the destruction of sensitive data. To safeguard your system, update Archive_Tar to version 1.4.12 or later immediately. Additionally, review your file handling processes to ensure stricter controls on symbolic links. Don’t forget to audit your system for any unauthorized changes! You’ve got this! By taking these steps, you’ll transform into a security hero in no time! 🛡️
