Advantech · Advantech R-Seenet · CVE-2021-21921
**Name of the Vulnerable Software and Affected Versions**
Advantech R-SeeNet (affected versions not specified)
**Description**
The issue is related to a lack of protection in the SQL query structure, which can be exploited through a specially-crafted HTTP request, potentially leading to SQL injection. This can be triggered by making authenticated HTTP requests to the `name filter` parameter, possibly through cross-site request forgery, or by exploiting the `name filter` parameter in the `user list.php` file. An attacker could use this vulnerability to disclose protected information remotely.
**Recommendations**
For Advantech R-SeeNet, as a temporary workaround, consider disabling the `name filter` parameter in the `user list.php` file until a patch is available.
Restrict access to the `user list.php` file to minimize the risk of exploitation.
Avoid using the `name filter` parameter in authenticated HTTP requests until the issue is resolved.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
