Cisco · Sa540 · CVE-2017-15805
**Name of the Vulnerable Software and Affected Versions**
Cisco Small Business SA520 and SA540 devices with firmware 2.1.71 and 2.2.0.7
**Description**
The issue allows for directory traversal in "scgi-bin/platform.cgi" via the `thispage` parameter, enabling the reading of arbitrary files.
**Recommendations**
For firmware 2.1.71, update to a version that fixes the directory traversal issue in "scgi-bin/platform.cgi".
For firmware 2.2.0.7, update to a version that fixes the directory traversal issue in "scgi-bin/platform.cgi".
As a temporary workaround, consider restricting access to the "scgi-bin/platform.cgi" endpoint to minimize the risk of exploitation.
Avoid using the `thispage` parameter in the affected endpoint until the issue is resolved.
