Workaround
As a temporary workaround, users can sanitize the path argument by validating and sanitizing user input. This can be achieved by using input validation techniques, such as whitelisting allowed characters or using regular expressions to ensure the path only contains valid characters. Additionally, it is recommended to implement proper input sanitization and validation throughout the application to mitigate the risk of other similar vulnerabilities.
Conclusion
diskusage-ng versions up to 0.2.4 are vulnerable to OS Command Injection, which allows an attacker to execute arbitrary commands on the system.
