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. |
| 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. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a SQL injection flaw in yanyutao0402 ChanCMS versions up to 3.3.2. It exists in the update function of the file /cms/article/update, where the cid parameter is not properly validated. An attacker can manipulate this parameter remotely to inject malicious SQL commands, potentially altering the database queries executed by the system. [2, 3]
How can this vulnerability impact me? :
The vulnerability can impact the confidentiality, integrity, and availability of the affected system. An attacker exploiting this flaw can remotely execute arbitrary SQL commands, which may lead to unauthorized data access, data modification, or disruption of service. Additionally, weak default backend credentials may allow further unauthorized access to the administration interface. [2, 3]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by testing the /cms/article/update endpoint for SQL injection via the 'cid' parameter. You can use tools like curl or sqlmap to send crafted requests to this endpoint and observe if SQL injection is possible. For example, using curl: curl -X POST 'http://target/cms/article/update' -d 'cid=1 OR 1=1' and checking for abnormal responses or errors. Alternatively, sqlmap can be used to automate detection: sqlmap -u 'http://target/cms/article/update' --data='cid=1' --risk=3 --level=5. Monitoring for unusual database errors or unexpected behavior in logs related to this endpoint may also help detect exploitation attempts. [2, 3]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include restricting access to the vulnerable /cms/article/update endpoint, especially from untrusted networks, and changing or disabling weak default backend credentials (default username 'chancms' and password '123456'). Since no vendor patch or fix is available, consider implementing input validation or filtering on the 'cid' parameter to prevent SQL injection. If possible, replace or upgrade ChanCMS to a secure version or alternative product. Monitoring and blocking suspicious requests targeting this endpoint is also recommended. [2, 3]
