CVE-2017-8329
Description
An issue was discovered on Securifi Almond, Almond+, and Almond 2015 devices with firmware AL-R096. The device provides a user with the capability of setting a name for the wireless network. These values are stored by the device in NVRAM (Non-volatile RAM). It seems that the POST parameters passed in this request to set up names on the device do not have a string length check on them. This allows an attacker to send a large payload in the "mssid_1" POST parameter. The device also allows a user to view the name of the Wifi Network set by the user. While processing this request, the device calls a function at address 0x00412CE4 (routerSummary) in the binary "webServer" located in Almond folder, which retrieves the value set earlier by "mssid_1" parameter as SSID2 and this value then results in overflowing the stack set up for this function and allows an attacker to control $ra register value on the stack which allows an attacker to control the device by executing a payload of an attacker's choice. If the firmware version AL-R096 is dissected using binwalk tool, we obtain a cpio-root archive which contains the filesystem set up on the device that contains all the binaries. The binary "goahead" is the one that has the vulnerable function that receives the values sent by the POST request. If we open this binary in IDA-pro we will notice that this follows a MIPS little endian format. The function sub_00420F38 in IDA pro is identified to be receiving the values sent in the POST parameter "mssid_1" at address 0x0042BA00 and then sets in the NVRAM at address 0x0042C314. The value is later retrieved in the function at address 0x00412EAC and this results in overflowing the buffer as the function copies the value directly on the stack.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Buffer overflow in Securifi Almond devices via long 'mssid_1' POST parameter allows remote code execution.
Vulnerability
A stack-based buffer overflow exists in Securifi Almond, Almond+, and Almond 2015 devices running firmware version AL-R096. The vulnerability is triggered when a user sets a wireless network name via the web interface. The POST parameter mssid_1 is not properly length-checked before being stored in NVRAM and later retrieved, leading to a buffer overflow in the routerSummary function at address 0x00412CE4 in the webServer binary. The affected binary is goahead, which processes the initial POST request. The vulnerability is present in MIPS little-endian architecture [1][2].
Exploitation
An attacker can exploit this vulnerability by sending a crafted POST request with an overly long mssid_1 parameter to the device's web interface. The device stores this value in NVRAM and later, when a user views the network name, the value is copied onto the stack without proper bounds checking. This overwrites the return address ($ra register) on the stack, allowing the attacker to control program flow. No authentication is required if the web interface is exposed, but user interaction is needed to trigger the vulnerable code path (viewing the network name). The attacker must have network access to the device [1][2].
Impact
Successful exploitation allows the attacker to execute arbitrary code on the device with root privileges, leading to full compromise of the device's functionality. This can result in information disclosure, denial of service, or use of the device as a pivot point for further attacks within the network [1][2].
Mitigation
As of the publication date, no patched firmware version has been released by Securifi. Users are advised to limit network access to the device's web interface and monitor for any official firmware updates. The devices may be end-of-life and no longer supported. There is no known workaround [1][2].
