Exploitability
| CWE ID | Description |
|---|---|
| CWE-89 | The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is an unauthenticated SQL Injection in the _RemoveRequest function of MB connect line's mbCONNECT24 and mymbCONNECT24 products. It occurs because special elements in a SQL DELETE command are not properly neutralized, allowing a high privileged remote attacker to manipulate the SQL query.
Exploiting this flaw enables the attacker to read the entire database and delete entries in a non-critical table.
The result can be a total loss of confidentiality and some loss of data integrity.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The vulnerability allows a high privileged remote attacker to read the entire database and delete entries in a non-critical table, resulting in a total loss of confidentiality and some loss of integrity.
Such a loss of confidentiality and integrity can negatively impact compliance with common standards and regulations like GDPR and HIPAA, which require protection of sensitive data and maintaining data integrity.
How can this vulnerability impact me? :
The vulnerability can lead to a total loss of confidentiality, meaning sensitive data stored in the database can be fully exposed to an attacker.
Additionally, there can be some loss of integrity due to the deletion of entries in a non-critical table, which might affect the reliability or correctness of certain data.
