Tenda · Tenda Fh1206 · CVE-2024-4020
**Name of the Vulnerable Software and Affected Versions**
Tenda FH1206 version 1.2.0.8(8155)
**Description**
A critical issue affects the `fromAddressNat` function of the `/goform/addressNat` file, where the manipulation of the `entrys` argument leads to a buffer overflow. This can be exploited remotely, potentially allowing an attacker to execute arbitrary code or cause a denial of service.
**Recommendations**
For Tenda FH1206 version 1.2.0.8(8155), as a temporary workaround, consider disabling the `fromAddressNat` function until a patch is available. Restrict access to the `/goform/addressNat` file to minimize the risk of exploitation. Avoid using the `entrys` argument in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
