Dell OpenManage Server Administrator, versions prior to 11.1.0.3, contains an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to Filesystem access for attacker.
Articles & Coverage 2
AnalysisAI
Unauthenticated path traversal in Dell OpenManage Server Administrator (OMSA) versions prior to 11.1.0.3 lets a remote attacker read arbitrary files from the managed node's filesystem. The flaw is reachable over the network with no credentials, no user interaction, and no special configuration (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N, 7.5), but impact is confidentiality-only: an attacker can exfiltrate files, not modify them or disrupt the service. …

Vulnerability AssessmentAI
| Exploitation | Requires network reachability to the Dell OpenManage Server Administrator managed-node service on a host running a version prior to 11.1.0.3; no authentication, no user interaction, and no non-default configuration are needed (AV:N/AC:L/PR:N/UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine priority for organizations running Dell OMSA on internet- or LAN-reachable management interfaces. … 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 | Vendor-released patch: upgrade Dell OpenManage Server Administrator to 11.1.0.3 or later on every managed node, following Dell advisory DSA-2026-403 (https://www.dell.com/support/kbdoc/en-us/000506586/dsa-2026-403-security-update-for-dell-openmanage-server-administrator-omsa-network-access-vulnerabilitiesv); apply the platform-appropriate package for Windows, RHEL 8.10/9.4, SLES 15, or Ubuntu 22.04, since the vulnerable code is shipped in each build and upgrading only one variant leaves the rest exposed. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory every host running Dell OpenManage Server Administrator and determine the installed version (pre-11.1.0.3 is affected on Windows patch bundles, RHEL 8.10, RHEL 9.4, SLES 15, and Ubuntu 22.04), separately flag any OMSA listener reachable from untrusted networks, and restrict network access to the OMSA port with firewall or load-balancer rules so only approved management networks and jump hosts can connect. …
