CVE-2018-1618

Vulnerability

IBM Security Privileged Identity Manager Virtual Appliance version 2.2.1 contains a directory traversal vulnerability. A remote attacker can send a specially-crafted URL request containing "dot dot" sequences (/../) to traverse directories on the system and view arbitrary files. This issue is identified by IBM X-Force ID 144343 [1].

Exploitation

An attacker does not require authentication or any special privileges. The attacker only needs network access to the appliance and the ability to send HTTP requests. By crafting a URL with path traversal sequences (e.g., ../../../../etc/passwd), the attacker can bypass intended access restrictions and read files outside of the web root directory.

Impact

Successful exploitation allows an attacker to read arbitrary files on the system. This can lead to disclosure of sensitive information, such as configuration files, credentials, or other confidential data stored on the appliance. The attack does not provide write access or code execution, but the information disclosure can be leveraged for further attacks.

Mitigation

IBM has released a fix as part of a security bulletin. Users should update to the latest version of IBM Security Privileged Identity Manager Virtual Appliance as specified in the vendor advisory [1]. No workarounds are documented; upgrading is the recommended mitigation.
