Affected Products

According to the Common Vulnerabilities and Exposures (CVE) database, the following Acronis Backup products are affected by CVE-2024-8767:

Exploit Details

The CVE-2024-8767 vulnerability is caused by an insecure configuration of file and directory permissions within the affected software products. As a result, sensitive data like usernames, email addresses, and authentication details can be accessed and modified without proper authorization. This may lead to unauthorized disclosure of confidential information and could allow an attacker to execute malicious actions on the server, such as creating unauthorized backups or altering existing backup data.

To exploit this vulnerability, an attacker needs local access to a vulnerable server running one of the affected Acronis Backup products. They can then potentially access, modify, or delete sensitive backup data using their local account's privileges or escalate their privileges to a higher level.

Code Snippet Example

The following example demonstrates how an attacker might use a Linux command to list the contents of a vulnerable Acronis Backup configuration file containing sensitive data:

$ cat /path/to/acronis/backup/config/file

This simple command could allow an attacker to view the contents of the configuration file, which may include sensitive information such as usernames, email addresses, and authentication details.

Remediation and Prevention

To address the security vulnerability CVE-2024-8767, the Acronis Backup software developers have released updated builds for the affected products. These updated builds include:

Acronis Backup plugin for DirectAdmin (Linux) build 147

To protect your systems from this vulnerability, it is recommended to promptly update the affected Acronis Backup products to the latest builds available. Additionally, routinely checking for and applying relevant software patches and updates can significantly reduce the risk of future vulnerabilities and security issues.
