Description:
An SQL Injection has been identified in the /adm_program/modules/ecards/ecard_send.php source file of the Admidio Application. The SQL Injection results in a compromise of the application's database. The value of ecard_recipients POST parameter is being directly concatenated with the SQL query in the source code causing the SQL Injection.
The SQL Injection can be exploited by a member user, using blind condition-based, time-based, and Out of band interaction SQL Injection payloads. I successfully exploited SQL Injections by causing Time Delays. Advancing the payload, I was able to exfiltrate data from the database based on trial and error conditions and step-wise enumerating the characters of the database name. This was done as a POC of SQL Injection. An attacker could simply drop the database by providing a single payload, steal data, and potentially update the database according to their will.
Impact:
SQL injection (SQLi) vulnerabilities can have serious consequences for the security of a web application and its underlying database. Attackers can use SQLi to access sensitive data, and modify, delete, or add data to the database. SQLi can also be potentially used to perform RCE.
Remediation:
Use parameterized queries or prepared statements instead of concatenating user input directly into SQL queries. Parameterized queries ensure that user input is treated as data and not executable queries. OR Sanitize the input before including it in the SQL Query.
Steps to Reproduce:
- Intercept the POST request to
/adm_program/modules/ecards/ecard_send.php, which is used to send photo as greeting card. - Change the value of
ecard_recipients%5B%5DPOST parameter to2%2bsleep(10). - Sending the request will cause a time delay.

The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker needs basic access or low-level privileges. No user interaction is needed for the attacker to exploit this vulnerability. The vulnerability can affect other systems as well, not just the initial system. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
Active exploitation in the wild has been confirmed. Immediate patching or mitigation is required.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
