| 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-2026-48236 is a high-severity SQL injection vulnerability found in Open ISES Tickets versions before 3.44.2, specifically in the db_loader.php file.
The vulnerability occurs because multiple POST parameters (ticketsdb, ticketshost, ticketsuser, ticketspassword) are concatenated directly into MySQLi connection arguments and dynamic SQL queries without proper sanitization.
This improper handling allows authenticated attackers to craft malicious requests that alter the intended SQL query behavior.
As a result, attackers can read, modify, or delete database contents unauthorizedly.
How can this vulnerability impact me? :
This vulnerability can have serious impacts including unauthorized access to sensitive data stored in the database.
Attackers with authenticated access can manipulate database queries to read confidential information, modify existing data, or delete important records.
Such actions can lead to data breaches, loss of data integrity, and disruption of service.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability involves SQL injection via multiple POST parameters (ticketsdb, ticketshost, ticketsuser, ticketspassword) in the db_loader.php file of Open ISES Tickets versions prior to 3.44.2.
To detect exploitation attempts on your system or network, you can monitor HTTP POST requests targeting db_loader.php and inspect the parameters for suspicious or malformed SQL syntax.
Example commands to detect such activity include using network traffic analysis tools or web server logs:
- Using grep on web server logs to find POST requests to db_loader.php: grep "POST /path/to/db_loader.php" /var/log/apache2/access.log
- Using tcpdump or tshark to capture HTTP POST traffic to the vulnerable endpoint and inspect parameters.
- Using intrusion detection systems (IDS) with SQL injection detection rules to alert on suspicious payloads in POST parameters.
What immediate steps should I take to mitigate this vulnerability?
The primary mitigation step is to upgrade Open ISES Tickets to version 3.44.2 or later, where this SQL injection vulnerability has been patched.
Until the upgrade can be applied, restrict access to the vulnerable db_loader.php endpoint to trusted authenticated users only.
Additionally, monitor and block suspicious POST requests targeting the vulnerable parameters (ticketsdb, ticketshost, ticketsuser, ticketspassword).
Implement web application firewall (WAF) rules to detect and block SQL injection attempts.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The vulnerability allows authenticated attackers to read, modify, or delete database contents by exploiting a SQL injection flaw. Such unauthorized access and manipulation of data can lead to breaches of sensitive information.
This type of data compromise can negatively impact compliance with common standards and regulations like GDPR and HIPAA, which require protection of personal and sensitive data against unauthorized access and alteration.
