Description

A vulnerability was found in aiyiyi121 SxDevOps 1.0/1.1. Affected by this issue is the function generate_host_task of the file backend/aiops/services.py of the component Command Handler. Performing a manipulation of the argument command results in command injection. Remote exploitation of the attack is possible. The patch is named 2b4bf8585c3e731e7a8af30801ea46680bc783f9. Applying a patch is the recommended action to fix this issue. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.

  "executiveSummary": "A command injection vulnerability exists in the aiyiyi121 SxDevOps application, versions 1.0 and 1.1.\nThe vulnerability resides within the Command Handler component and stems from improper neutralization of user-supplied input.\nThis flaw allows remote, unauthenticated attackers to execute arbitrary system commands on the underlying host operating system with the privileges of the application process.\nSuccessful exploitation results in full system compromise, potential data exfiltration, and unauthorized service manipulation.\nThe risk is classified as critical due to the remote exploitability of the vector and the severity of the potential impact on the host environment.",
  "technicalDetails": "The vulnerability is located in the function generate_host_task within the file backend/aiops/services.py. The root cause is the insecure passing of the 'command' argument to a system shell execution function without adequate sanitization or input validation.\nSpecifically, the application takes user-controlled data via the 'command' argument and integrates it directly into a command string that is subsequently interpreted and executed by the host's shell. By injecting shell metacharacters such as ';', '&&', or '|', an attacker can terminate the intended command and append malicious payloads.\nThe attack flow begins when an attacker sends a crafted request to the SxDevOps application targeting the Command Handler. The input provided in the 'command' parameter is processed by the generate_host_task function, which fails to employ parameterized interfaces or safe API alternatives that avoid shell interpretation (e.g., execve or similar system calls that do not invoke a shell).\nOnce the malicious payload is injected, the application executes the concatenated string. For example, injecting 'original_command; cat /etc/passwd' would cause the system to execute the legitimate task followed immediately by the unauthorized extraction of system files. Because this occurs at the backend layer, the attacker gains the ability to execute code with the context and permissions of the service account running the SxDevOps backend.\nThe exploitation is possible remotely, requiring no prior authentication. The vulnerability impacts the integrity and availability of the server hosting the application, as an attacker can disable services, create persistent backdoors, or pivot into the internal network environment if the host is part of a larger infrastructure. The lack of validation on input allows for arbitrary command chaining, making the attack surface significant."
