Exploitation Conditions

Exploitation requires (1) adjacent-network access per CVSS AV:A - the attacker must reach the OpenManage Enterprise console from the same logical network segment / management network, not the open internet; and (2) a low-privileged authenticated account on OME (PR:L). No user interaction is required (UI:N). The specific product feature, parameter, or command path that accepts the injected argument delimiters is not described in the available sources. These prerequisites - network adjacency plus valid low-privilege credentials - materially limit realistic exploitation to actors already inside the management network with an account.

Impact

This is a moderate-severity issue (Dell CVSS 4.6) that signals do NOT elevate to urgent priority. The CVSS 3.1 vector (AV:A/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N) constrains exploitation to an adjacent-network attacker who already holds a low-privileged authenticated account, with only partial confidentiality and integrity impact and no availability impact - consistent with the CWE-88 argument-injection class where an attacker influences command arguments rather than achieving clean arbitrary code execution. No EPSS score, KEV listing, or POC is present in the supplied data, so there is no public evidence of exploitation or exploit tooling. The vuln.today decision label is 'this_month' (not act_now/emergency), aligning with the modest CVSS and absent exploitation signals. Signals are therefore consistent rather than conflicting: a legitimately lower-risk, defense-in-depth fix rather than a drop-everything emergency. The main caveat is that the advisory text summarizes but does not detail the exact injectable command path, so the real-world impact ceiling of the 'command execution' outcome cannot be fully verified from the available data.

Exploit ScenarioDerived

An attacker who already holds a low-privileged account on the OpenManage Enterprise console and has adjacent-network access (same L2 segment / management network) submits input containing crafted argument delimiters that get passed into a system command, causing injected arguments to execute. No public exploit code or POC is identified in the available data, and the specific injectable parameter is not described in the supplied advisory reference.

AnalysisAIv1 – Nov 02, 2026

Argument injection in Dell OpenManage Enterprise versions prior to 4.8.0 allows a low-privileged authenticated user who can reach the appliance over an adjacent network segment to slip attacker-controlled delimiters into a command the product builds, resulting in command execution on the management appliance. The impact is bounded in the CVSS vector to partial confidentiality and integrity loss with no availability effect (C:L/I:L/A:N), giving a moderate base score of 4.6. Exploitation requires both presence on the management network (AV:A) and a valid low-privilege OME account (PR:L), so practical risk is concentrated among insiders or actors who have already established a foothold on the management segment; no public exploit has been identified at the time of analysis and the priority label is this_month, not act_now.

RemediationAI

Dell addresses this in OpenManage Enterprise 4.8.0, so the primary action is to upgrade any appliance running an earlier release to 4.8.0 or later, following the guidance and any prerequisite upgrade path in DSA-2026-467 (https://www.dell.com/support/kbdoc/en-us/000523220/dsa-2026-467-security-update-for-dell-openmanage-enterprise-vulnerabilities). Because the assessed attack vector requires the attacker to be on the same logical network segment as the console, exposure can be reduced while the upgrade is scheduled by limiting which hosts and subnets can reach the OME management interface and by auditing and paring back low-privileged accounts - trade-offs are reduced administrative convenience and the need to enumerate legitimate operator sources first. Note that these are exposure-reduction measures consistent with the assessed prerequisites, not vendor-published workarounds; no vendor workaround is listed in the available references, and the supplied data does not indicate a fix for any branch other than 4.8.0.

Technical ContextAI · show details

The flaw is classified as CWE-88, Improper Neutralization of Argument Delimiters in a Command, which is the argument-level sibling of OS command injection. Rather than failing to escape shell metacharacters, the product assembles a command line and does not prevent user-supplied input from being interpreted as separate arguments or options, so crafted delimiter sequences can alter the semantics of the invoked command. Dell OpenManage Enterprise is a Java-based infrastructure management console used to discover, monitor, patch and orchestrate PowerEdge servers and related devices, and it typically runs with elevated service privileges on its own appliance, which is why argument injection matters even at a modest CVSS rating. The affected scope is captured by the wildcard CPE cpe:2.3:a:dell:openmanage_enterprise:*:*:*:*:*:*:*:*, with the vendor advisory stating the fix lands in 4.8.0. The specific feature, parameter, endpoint or underlying command path that accepts the injected delimiters is not described in the available sources, so the exact trigger remains unverified; what is confirmed from the vector is that the attacker needs adjacent-network reachability and a low-privileged authenticated account, and that no user interaction is required.
