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
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The SQL injection vulnerability in MGB OpenSource Guestbook 0.7.0.2 allows unauthenticated attackers to extract sensitive database information, including table and column names. This exposure of sensitive data can lead to unauthorized access to personal or protected information.
Such unauthorized data access and potential data breaches can negatively impact compliance with common standards and regulations like GDPR and HIPAA, which require protection of sensitive personal and health information.
Organizations using the affected software may face increased risk of non-compliance due to the vulnerability's impact on confidentiality and data security.
Can you explain this vulnerability to me?
CVE-2018-25411 is a high-severity SQL injection vulnerability found in MGB OpenSource Guestbook version 0.7.0.2. It exists in the email.php file where the 'id' parameter does not properly sanitize input, allowing unauthenticated attackers to inject malicious SQL code.
Attackers can send specially crafted GET requests with SQL payloads through the 'id' parameter to execute arbitrary SQL commands on the database.
This can lead to extraction of sensitive database information such as table and column names.
How can this vulnerability impact me? :
This vulnerability can have significant impacts including unauthorized access to sensitive database information.
- Attackers can extract confidential data such as database schema details.
- It may lead to data leakage or exposure of sensitive information.
- Since the vulnerability allows execution of arbitrary SQL commands, it could potentially be used to manipulate or corrupt data.
The CVSS v4.0 score of 8.8 reflects a high risk primarily due to the impact on confidentiality.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by monitoring for suspicious GET requests to the email.php file that include crafted SQL payloads in the 'id' parameter.
One way to detect exploitation attempts is to analyze web server logs for unusual or malformed 'id' parameter values that contain SQL syntax or keywords.
For example, you can use commands like the following to search for suspicious requests in Apache or Nginx logs:
- grep -i "email.php?id=" /var/log/apache2/access.log | grep -E "(union|select|insert|update|delete|drop|--|')"
- grep -i "email.php?id=" /var/log/nginx/access.log | grep -E "(union|select|insert|update|delete|drop|--|')"
Additionally, using web application firewalls (WAFs) or intrusion detection systems (IDS) with SQL injection detection rules can help identify and alert on such malicious requests.
What immediate steps should I take to mitigate this vulnerability?
The immediate step to mitigate this vulnerability is to upgrade MGB OpenSource Guestbook to version 0.7.1.1 or later, where the issue has been addressed.
If upgrading is not immediately possible, you should implement input validation and sanitization on the 'id' parameter in email.php to prevent SQL injection.
Additionally, consider deploying a web application firewall (WAF) to block malicious SQL injection attempts targeting the 'id' parameter.
Monitoring and restricting access to the vulnerable endpoint and applying least privilege principles to the database user can also reduce the risk.
