Summary

In SapphireIMS 5.0, it is possible to use the hardcoded credential in clients (username: sapphire, password: ims) and gain access to the portal. Once the access is available, the attacker can inject malicious OS commands on “ping”, “traceroute” and “snmp” functions and execute code on the server. We also observed the same is true if the JSESSIONID is completely removed.

Exploit prediction

2.13% chance of exploitation in the next 30 days, higher than 82% of all scored CVEs (FIRST EPSS, 2026-11-08).

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.
