Exploitability
| CWE ID | Description |
|---|---|
| CWE-74 | The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. |
| 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?
CVE-2026-5646 is a SQL injection vulnerability found in the Easy Blog Site PHP application, specifically in the login.php file.
The vulnerability occurs because the application does not properly filter or sanitize the username and password inputs before querying the database to verify user accounts.
This allows an attacker to inject malicious SQL code through the login fields, bypassing authentication and gaining unauthorized access to any user account.
A proof of concept shows that any password can be used to log in to other user accounts without proper credentials.
How can this vulnerability impact me? :
This vulnerability can have serious impacts including unauthorized access to user accounts.
An attacker can bypass authentication controls and potentially access sensitive user data or perform actions on behalf of other users.
Since the attack can be initiated remotely, it increases the risk of exploitation without physical access to the system.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by testing the login.php functionality for SQL injection flaws. Specifically, you can attempt to inject SQL code into the username or password fields to see if unauthorized access is granted.
A common method is to use SQL injection testing tools or manual commands such as submitting payloads like ' OR '1'='1' -- in the username or password fields to check if authentication can be bypassed.
For example, using curl to test the login endpoint with an injection payload:
- curl -X POST -d "username=' OR '1'='1' -- &password=anything" http://targetsite/login.php
If the response indicates successful login or access without valid credentials, it confirms the presence of the SQL injection vulnerability.
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include sanitizing and validating all user inputs on the login.php page, especially the username and password fields.
Implement prepared statements or parameterized queries to prevent SQL injection attacks.
Additionally, restrict direct database queries with raw user input and apply least privilege principles to database accounts.
If possible, apply any available patches or updates from the software supplier to fix the vulnerability.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The SQL injection vulnerability in Easy Blog Site 1.0 allows attackers to bypass authentication and gain unauthorized access to user accounts. This unauthorized access can lead to exposure or manipulation of personal data, which may violate data protection regulations such as GDPR and HIPAA that require safeguarding user information against unauthorized access.
Therefore, this vulnerability negatively impacts compliance with common standards and regulations by increasing the risk of data breaches and unauthorized data access.
