Dell has released a patch for iDRAC Service Module (iSM), updating it to version 6.0.3.0. Users are advised to update their iSM to this version as soon as possible.<br \/>\nIn cases where immediate patching is not feasible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. However, these measures are merely palliative and do not address the core vulnerability. As such, patching should still be carried out as soon as practicable.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview The CVE-2025-38743 vulnerability is a significant security issue that affects Dell&#8217;s iDRAC Service Module (iSM) in versions prior to 6.0.3.0.
