NetWorker Management Console: Improper Neutralization of Server-Side Includes (SSI) Within a Web Page
CVE-2025-21103 is a high-severity improper neutralization of server-side includes (SSI) within a web page vulnerability in NetWorker Management Console from Dell, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version 19.10.0.7 as the first without the flaw, so updating NetWorker Management Console to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.22% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update NetWorker Management Console to 19.10.0.7 or a later version.
- Update Networker to 19.10.0.7 or a later version.
- Read the advisory on dell.com for workarounds and exact fixed builds.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
