Exploitability
| CWE ID | Description |
|---|---|
| CWE-119 | The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data. |
| CWE-120 | The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in the UTT θΏε 512W device up to version 3.1.7.7-171114, specifically in the strcpy function within the /goform/formConfigFastDirectionW file. It occurs due to improper handling of the 'ssid' argument, which leads to a buffer overflow. This means that an attacker can remotely send specially crafted input to overflow the buffer, potentially causing unexpected behavior or allowing execution of malicious code.
How can this vulnerability impact me? :
The vulnerability can be exploited remotely without any authentication or user interaction, allowing an attacker to cause a buffer overflow. This can lead to severe impacts such as complete compromise of the affected device, including unauthorized access, data manipulation, or denial of service. Given the high CVSS scores (up to 10.0), the impact includes confidentiality, integrity, and availability being fully compromised.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by monitoring for suspicious POST requests to the /goform/formConfigFastDirectionW endpoint, especially those containing unusually large or malformed 'ssid' parameters. A practical detection method is to capture and analyze HTTP traffic targeting the router's IP (commonly 192.168.1.1) for POST requests with the 'wrlessMode' parameter set to 4 and oversized SSID values. For example, using tcpdump or Wireshark to filter HTTP POST requests to the endpoint can help identify potential exploit attempts. A sample tcpdump command might be: tcpdump -A -s 0 'tcp dst port 80 and host 192.168.1.1' | grep '/goform/formConfigFastDirectionW'. Additionally, inspecting web server logs for POST requests to this endpoint with large payloads or unusual SSID strings can aid detection. [1, 3]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include restricting access to the vulnerable device's management interface, such as limiting network exposure to trusted hosts only and disabling remote management if enabled. Since no patches or vendor fixes are currently available, consider replacing the affected UTT θΏε 512W device with a non-vulnerable alternative. Additionally, monitor network traffic for exploit attempts and apply network-level protections like firewall rules to block suspicious POST requests targeting /goform/formConfigFastDirectionW. Implementing intrusion detection or prevention systems to detect and block exploit attempts can also help reduce risk. [2]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by monitoring for suspicious POST requests to the /goform/formConfigFastDirectionW endpoint, especially those containing unusually large or malformed 'ssid' parameters. A detection approach could involve capturing HTTP traffic to the router and filtering for POST requests targeting this endpoint with large payloads. For example, using tcpdump or tshark to capture traffic and grep or Wireshark to filter for POST requests to /goform/formConfigFastDirectionW. A sample command to capture such traffic might be: tcpdump -i <interface> -A 'tcp port 80 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) > 0)' | grep '/goform/formConfigFastDirectionW'. Additionally, inspecting logs for repeated or failed authentication attempts or unusual POST data sizes could help detect exploitation attempts. [1, 3]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include restricting access to the vulnerable device's management interface, such as limiting access to trusted IP addresses or networks, disabling remote management if enabled, and monitoring for exploit attempts. Since no patches or vendor mitigations are currently available, consider replacing the affected device with a non-vulnerable model. Additionally, applying network-level protections like firewall rules to block malicious POST requests targeting /goform/formConfigFastDirectionW can reduce risk. [2]
