lares: Use of Hard-coded Password
CVE-2025-15111 is a critical-severity use of hard-coded password vulnerability in lares from Ksenia Security S.p.A., with a CVSS 3.1 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 lares versions: 1.6; 1.0.0.15. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.58% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of lares you run against the affected versions below, and install the vendor's latest release.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
Ksenia Security lares (legacy model) version 1.6 contains a default credentials vulnerability that allows unauthorized attackers to gain administrative access. Attackers can exploit the weak default administrative credentials to obtain full control of the home automation system.

The underlying weakness: Use of Hard-coded Password
The product contains a hard-coded password, which it uses for its own inbound authentication or for outbound authentication to external components.
How developers prevent this class of flaw
- For outbound authentication: store passwords outside of the code in a strongly-protected, encrypted configuration file or database that is protected from access by all outsiders, including other local users on the same system. Properly protect the key (CWE-320). If you cannot use encryption to protect the file, then make sure that the permissions are as restrictive as possible.
- For inbound authentication: Rather than hard-code a default username and password for first time logins, utilize a first login mode that requires the user to enter a unique strong password.
- Perform access control checks and limit which entities can access the feature that requires the hard-coded password. For example, a feature might only be enabled through the system console instead of through a network connection.
