Summary

The absence of filters when loading some sections in the web application of the vulnerable device allows potential attackers to inject malicious code that will be interpreted when a legitimate user accesses the web section (MAIL SERVER) where the information is displayed. Injection can be done on parameter MAIL_RCV. When a legitimate user attempts to review NOTIFICATION/MAIL SERVER, the injected code will be executed.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
