Exploitability
| CWE ID | Description |
|---|---|
| CWE-20 | The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. |
| CWE-78 | The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is an OS command injection flaw in the Blue Angel Software Suite running on embedded Linux devices. It occurs because the application does not properly sanitize user input passed to the system-level ping command via the ping_addr parameter in the webctrl.cgi script. An authenticated attacker can exploit this by sending a crafted GET request with shell metacharacters appended to the ping_addr parameter, allowing arbitrary command execution as the root user. Default and backdoor credentials can be used to gain access and exploit this issue. [1]
How can this vulnerability impact me? :
Exploitation of this vulnerability allows an attacker with authenticated access to execute arbitrary commands on the affected device with root privileges. This can lead to full compromise of the embedded Linux device, including unauthorized control, data theft, disruption of services, or further network penetration. Since default and backdoor credentials can be used, the risk of exploitation is higher if these credentials are not changed. [1]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
Detection can be performed by checking for the presence of the vulnerable software and attempting authenticated access using default or backdoor credentials. Specifically, you can send an HTTP GET request to the target on the relevant port and check if the response contains the string '/cgi-bin/webctrl.cgi?action=index_page' to verify the vulnerable Blue Angel Software Suite is running. Then, attempt to authenticate using known default or backdoor accounts such as 'blueangel:blueangel', 'guest:guest', or other listed credentials. After successful login, you can test command injection by sending a crafted GET request to '/cgi-bin/webctrl.cgi?action=pingtest_update' with the 'ping_addr' parameter set to '127.0.0.1;' followed by a harmless shell command (e.g., 'id') to see if command execution is possible and the output is reflected in the response. This process can be scripted or manually done using tools like curl or custom scripts. [1]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include changing or disabling all default and backdoor credentials to prevent unauthorized authenticated access. Restrict access to the web interface to trusted networks or IP addresses to reduce exposure. If possible, disable or restrict the vulnerable ping command functionality in the webctrl.cgi script. Monitor and log access attempts to detect exploitation attempts. Applying any available patches or updates from the vendor is recommended once available. Until a patch is applied, avoid exposing the device's management interface to untrusted networks. [1]
