MediumCVSS 6.3 · v4.0—No exploit No fix recorded

Noroxi assessment

Priority: Monitor (action score 25/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.22% (FIRST EPSS).
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

Wazuh provisioning scripts and Dockerfiles contain an insecure transport vulnerability where curl is invoked with the -k/--insecure flag, disabling SSL/TLS certificate validation. Attackers with network access can perform man-in-the-middle attacks to intercept and modify downloaded dependencies or code during the build process, leading to remote code execution and supply chain compromise.

Root cause

A certificate validation error is silently swallowed instead of terminating the connection. Often, code added for a test environment makes its way into production.
