Name of the Vulnerable Software and Affected Versions Advantech R-SeeNet (affected versions not specified)

Description The issue is related to the incorrect handling of the desc filter parameter in the device list component, which can lead to SQL injection. An attacker can exploit this by making authenticated HTTP requests or through cross-site request forgery. This allows a remote attacker to conduct cross-site scripting attacks by sending specially crafted SQL queries.

Recommendations As a temporary workaround, consider disabling the desc filter parameter in the affected component until a patch is available. Restrict access to the device list component to minimize the risk of exploitation. Avoid using the desc filter parameter in authenticated HTTP requests until the issue is resolved.
