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?
CVE-2025-26186 is a Blind SQL Injection vulnerability in the openSIS v.9.1 application, specifically in the Ajax.php endpoint. It occurs because the 'id' parameter is not properly sanitized, allowing a remote attacker to manipulate it and cause SQL errors. This lets the attacker infer information from the database by sending crafted requests, potentially leading to unauthorized data access or manipulation. [1]
How can this vulnerability impact me? :
This vulnerability can allow a remote attacker to execute arbitrary code or manipulate the database by exploiting the unsanitized 'id' parameter. This could lead to unauthorized access to sensitive data, data corruption, or other malicious actions within the openSIS application. [1]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by sending crafted HTTP requests to the vulnerable endpoint and observing the server's response for SQL error messages. Specifically, you can test the `id` parameter in the URL `/Ajax.php?modname=tools/GenerateApi.php&modfunc=remove&id=1&ajax=true` by appending a single quote (') to the `id` value. For example, using curl: `curl -i 'http://<target>/Ajax.php?modname=tools/GenerateApi.php&modfunc=remove&id=1'%27&ajax=true'`. If the server returns an SQL error, it indicates the presence of the Blind SQL Injection vulnerability. [1]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include applying input validation and sanitization on the `id` parameter to prevent SQL injection. If a patch or update is available from the openSIS maintainers addressing this issue, apply it promptly. Additionally, consider implementing web application firewall (WAF) rules to block malicious payloads targeting the `id` parameter in the vulnerable endpoint until a permanent fix is deployed. [1]
