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 DeleteSysLogEntry function. A highly privileged remote attacker can exploit improper neutralization of special elements in a SQL DELETE command. This allows the attacker to read the entire database and delete entries in a non-critical table.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
This vulnerability can result in a total loss of confidentiality and some loss of integrity due to an unauthenticated SQL Injection allowing reading of the whole database and deletion of entries in a non-critical table.
Such a loss of confidentiality and integrity could negatively impact compliance with standards and regulations like GDPR and HIPAA, which require protection of sensitive data and maintaining data integrity.
How can this vulnerability impact me? :
Exploitation of this vulnerability can lead to a total loss of confidentiality, meaning sensitive data in the database can be fully exposed. Additionally, there can be some loss of integrity due to deletion of entries in a non-critical table.
