D-Link DCS-2530L and DCS-2670L Devices Unspecified
CVE-2020-25078 is a high-severity vulnerability in Dcs-4603 Firmware from D-Link, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.04.02 as the first without the flaw, so updating Dcs-4603 Firmware to that release or later removes the exposure. CISA added it to the Known Exploited Vulnerabilities catalogue on August 5, 2025, which means attacks have been observed in the wild.
Attackers are already exploiting this vulnerability, according to CISA.
What to do
- Update Dcs-4603 Firmware to 1.04.02 or a later version.
- Update Dcs-4622 Firmware to 2.01.10 or a later version.
- Update Dcs-4701e Firmware to 2.03.01 or a later version.
- CISA's required action: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
- Read the advisory on supportannouncement.us.dlink.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
