Cross-Site Request Forgery (CSRF)
On the D-Link DIR-615 before v20.12PTb04, if a victim logged in to the Router's Web Interface visits a malicious site from another Browser tab, the malicious site then can send requests to the victim's Router without knowing the credentials (CSRF). An attacker can host a page that sends a POST request to Form2File.htm that tries to upload Firmware to victim's Router. This causes the router to reboot/crash resulting in Denial of Service. An attacker may succeed in uploading malicious Firmware.
CWE-352 - Cross-Site Request Forgery (CSRF)
Cross-Site Request Forgery (CSRF) is a vulnerability that allows an attacker to make arbitrary requests in an authenticated vulnerable web application and disrupt the integrity of the victim’s session. The impact of a successful CSRF attack may range from minor to severe, depending upon the capabilities exposed by the vulnerable application and privileges of the user. An attacker may force the user to perform state-changing requests like transferring funds, changing their email address or password etc. However, if an administrative level account is affected, it may compromise the whole web application and associated sensitive data.
