D-View: Use of Hard-coded Cryptographic Key
CVE-2023-32169 is a critical-severity use of hard-coded cryptographic key vulnerability in D-View from D-Link, with a CVSS 3.0 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected D-View versions: DLink D-View8 1.0.2.13; 2.0.1.27 and earlier. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 56.1% chance of exploitation within 30 days, which is in the top 0.94% of all scored CVEs.
Exploitation in the next 30 days is more likely than not, according to EPSS.
What to do
- Check which version of D-View you run against the affected versions below, and install the vendor's latest release.
- 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.
