CVE-2020-4782

Name of the Vulnerable Software and Affected Versions IBM WebSphere Application Server versions 7.0 through 9.0

Description The issue allows a remote attacker to traverse directories on the system by sending a specially-crafted URL request containing dot dot sequences (/../) to view arbitrary files on the system.

Recommendations For IBM WebSphere Application Server versions 7.0 through 9.0, consider restricting access to sensitive files and directories to minimize the risk of exploitation. As a temporary workaround, consider implementing additional validation and sanitization of URL requests to prevent directory traversal attacks.
