Tenda FH1201/FH1206 HTTP Request webtypelibrary strcat stack-based overflow

A flaw has been found in Tenda FH1201 and FH1206 1.2.0.14(408)/1.2.0.8(8155). This impacts the function strcat of the file /goform/webtypelibrary of the component HTTP Request Handler. This manipulation of the argument webSiteId causes stack-based buffer overflow. The attack is possible to be carried out remotely. The exploit has been published and may be used.

Tenda FH1206 v02.03.01.35 was discovered to contain a stack-based buffer overflow vulnerability in the fromPptpUserAdd function. The vulnerability can be triggered via the modino, username, newpwd, or pptpdnetseg parameters, all of which are passed via HTTP POST and used in unsafe sprintf calls without proper length validation. A remote attacker can exploit this flaw through a crafted POST request, which may cause a Denial of Service (DoS). In certain scenarios, this issue could potentially be leveraged to achieve remote code execution.

Tenda FH1206 addressNat fromAddressNat buffer overflow

A vulnerability was found in Tenda FH1206 1.2.0.8(8155) and classified as critical. This issue affects the function fromAddressNat of the file /goform/addressNat. The manipulation of the argument entrys leads to buffer overflow. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-261671. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
