Openwrt · Openwrt · CVE-2021-28961
Name of the Vulnerable Software and Affected Versions:
OpenWrt 19.07
Description:
The issue is related to the DDNS package in OpenWrt 19.07, where the `detail.lua` file allows remote authenticated users to inject arbitrary commands via POST requests to the `/cgi-bin/luci` API endpoint, specifically the `detail.lua` script. This could potentially impact the confidentiality, integrity, and availability of protected information.
Recommendations:
For OpenWrt 19.07, consider disabling the `detail.lua` script in the DDNS package as a temporary workaround until a patch is available. Restrict access to the DDNS package to minimize the risk of exploitation. Avoid using the DDNS package until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
