Asus · Asus Rp-Ac52 · CVE-2016-6558
**Name of the Vulnerable Software and Affected Versions**
ASUS RP-AC52 access point firmware version 1.0.1.1s and possibly earlier
**Description**
A command injection issue exists in the apply.cgi web interface, specifically in the `action script` parameter. This parameter is used to specify a script for execution when the `action mode` parameter does not contain a valid state. If the input provided by `action script` does not match one of the hardcoded options, it will be executed as an argument of either a system() or an eval() call, allowing arbitrary commands to be executed.
**Recommendations**
For firmware version 1.0.1.1s and possibly earlier, consider restricting access to the apply.cgi web interface until a patch is available. As a temporary workaround, avoid using the `action script` parameter in the affected web interface to minimize the risk of exploitation.
