Ivanti · Ivanti Avalanche · CVE-2021-30497
**Name of the Vulnerable Software and Affected Versions**
Ivanti Avalanche (Premise) version 6.3.2
**Description**
The issue allows remote unauthenticated users to read arbitrary files via Absolute Path Traversal. This is due to the `imageFilePath` parameter not being verified to be within the scope of the image folder when processed by the "/AvalancheWeb/image" endpoint. An attacker can obtain sensitive information by exploiting this, for example, by accessing the "C:/Windows/system32/config/system.sav" file.
**Recommendations**
For Ivanti Avalanche (Premise) version 6.3.2, as a temporary workaround, consider restricting access to the "/AvalancheWeb/image" endpoint to minimize the risk of exploitation. Additionally, avoid using the `imageFilePath` parameter in this endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
