Dell OpenManage Server Administrator, versions prior to 11.1.0.3, contains an Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to Remote execution.
Articles & Coverage 2
AnalysisAI
Unauthenticated remote OS command injection in Dell OpenManage Server Administrator (OMSA) managed-node builds prior to 11.1.0.3 allows a network-reachable attacker to run arbitrary operating-system commands on the host, yielding full confidentiality, integrity, and availability impact (CVSS 8.1, C:H/I:H/A:H, CWE-78). Affected deployments include the Windows managed-node patch build and the managed-node packages for RHEL 8.10, RHEL 9.4, SLES 15, and Ubuntu 22.04; the vendor rates attack complexity as high (AC:H), so successful exploitation hinges on a specific non-default condition, timing, or crafted-input constraint rather than a single trivial request. …

Vulnerability AssessmentAI
| Exploitation | Requires network access to the Dell OpenManage Server Administrator managed-node service on an affected host running a version prior to 11.1.0.3; no authentication and no user interaction are needed (PR:N/UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is the most severe member of the Dell DSA-2026-403 (KBdoc 000506586) bundle of OMSA network-access vulnerabilities, and unlike its confidentiality-only siblings (CVE-2026-81438, CVE-2026-66269, CVE-2026-81439) this one is a genuine unauthenticated remote OS command injection (CWE-78) yielding full C:H/I:H/A:H. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the vendor-released patch: upgrade Dell OpenManage Server Administrator managed node to version 11.1.0.3 or later on every affected platform (Windows, RHEL 8.10, RHEL 9.4, SLES 15, Ubuntu 22.04), using the update bundle referenced in Dell advisory DSA-2026-403 at https://www.dell.com/support/kbdoc/en-us/000506586/dsa-2026-403-security-update-for-dell-openmanage-server-administrator-omsa-network-access-vulnerabilitiesv. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory every host running Dell OpenManage Server Administrator managed-node builds prior to 11.1.0.3 - including the Windows managed-node patch build and the managed-node packages for RHEL 8.10, RHEL 9.4, SLES 15, and Ubuntu 22.04 - and immediately restrict network reachability to the OMSA management interface, allowing access only from a dedicated management VLAN or hardened jump host and removing any exposure to general user or internet-facing networks. …
