Description

A vulnerability was determined in aiyiyi121 SxDevOps 1.0/1.1. This affects the function update of the file backend/rbac/serializers.py of the component UserSerializer. Executing a manipulation can lead to improper privilege management. The attack can be executed remotely. This patch is called 2b4bf8585c3e731e7a8af30801ea46680bc783f9. It is best practice to apply a patch to resolve 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 vulnerability classified as improper privilege management exists in aiyiyi121 SxDevOps versions 1.0 and 1.1.\nThe flaw resides within the UserSerializer component, specifically impacting the update function defined in backend/rbac/serializers.py.\nThis vulnerability allows a remote attacker to manipulate user data, potentially leading to unauthorized privilege escalation or modification of sensitive user attributes.\nThe risk is high, as the vulnerability is remotely exploitable and directly affects the integrity and security of the application's role-based access control (RBAC) mechanism.\nSuccessful exploitation could result in unauthorized administrative access, credential compromise, or the circumvention of security controls implemented within the system.",
  "technicalDetails": "The vulnerability is located in the backend/rbac/serializers.py file within the UserSerializer class, specifically affecting the update method. This component is responsible for handling the serialization and deserialization of user data during update operations in the application's API.\nThe root cause stems from a failure to adequately restrict the fields that can be modified by a client during an update request. In many Django-based applications, serializers are used to map incoming JSON requests to database models. If the UserSerializer does not explicitly define or restrict editable fields, an attacker can supply unauthorized key-value pairs in the payload.\nSpecifically, within the update function, the application fails to validate the current user's authorization to modify sensitive fields, such as 'is_staff', 'is_superuser', or associated group roles. When the update function processes the serialized input, it blindly applies the incoming data to the underlying User model instance.\nThe attack flow proceeds as follows: An authenticated remote attacker identifies that the UserSerializer endpoint does not implement field-level permissions. The attacker crafts an HTTP PUT or PATCH request targeting the user profile endpoint. The request payload includes sensitive fields that the attacker should not have authorization to modify (e.g., setting 'is_superuser' to true). The backend/rbac/serializers.py code then deserializes this input without checking if the user session has sufficient privileges to alter those specific fields. Consequently, the database record is updated with the escalated privileges.\nThis vulnerability is remotely exploitable and does not require complex local access. While authentication may be required to reach the endpoint, the lack of granular privilege checks allows for horizontal or vertical privilege escalation. The impact is significant, as it fundamentally breaks the RBAC model, potentially granting an attacker full administrative control over the SxDevOps application. This behavior is consistent with improper input validation and insufficient authorization controls within the serialization layer, common in improperly configured Django REST framework implementations."
