Exploitation Conditions

Exploitation requires the attacker to already possess high-privileged local access (administrator on Windows, root/elevated on Linux or ESXi) on a host running Dell iDRAC Service Module at a version below 6.1.1.0. There is no network path and no default-configuration remote trigger - the flaw cannot be reached without prior local, privileged foothold, which substantially limits realistic risk to post-compromise scenarios on managed Dell PowerEdge servers.

Impact

This is a low-to-moderate real-world priority despite being a code-injection (CWE-94) flaw. The CVSS 3.1 vector (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L, base 4.2) is the dominant signal and it is internally consistent with the description: AV:L confirms local-only access and PR:H confirms the attacker must already hold high privileges on the host, so this is a privilege-boundary escalation rather than a remote compromise. There is no EPSS score, no CISA KEV listing, and no POC in the provided data, so there is no evidence of active or probable exploitation - no public exploit identified at time of analysis. The only decision signal elevating it is the vuln.today 'this_month' label, which is a routine-patch cadence, not act_now or emergency. The impact is uniformly Low across C/I/A and scope is unchanged (S:U), so even successful exploitation yields limited elevation. Note the tag set includes 'RCE', which conflicts with the AV:L local, high-privilege-required reality of this CVE - this reads as a local elevation-of-privilege issue, not remote code execution; treat the RCE label with skepticism.

Exploit ScenarioDerived

An attacker who has already obtained high-privileged (administrator/root) local access to a Dell PowerEdge host running the iDRAC Service Module prior to 6.1.1.0 injects attacker-controlled code that the service module generates or executes, gaining elevated privileges on the host. Because CVSS specifies AV:L and PR:H, this is a post-compromise local escalation step, not an initial-access vector. No public exploit code is identified in the available data.

AnalysisAIv1 – Oct 28, 2026

Improper control of code generation (CWE-94) in Dell iDRAC Service Module (iSM) versions prior to 6.1.1.0 for Windows, Linux, and ESXi lets a high-privileged local attacker inject code and elevate privileges on the host. Because exploitation requires an attacker to already hold administrator or root-level access on the managed server, the flaw is primarily a post-compromise concern rather than a remotely reachable entry point; CVSS is 4.2 (AV:L/PR:H). No public exploit is identified in the available data and the issue is not in CISA KEV, so remediation should be scheduled through normal patch cycles.

RemediationAI

Dell addresses this in DSA-2026-458; upgrade Dell iDRAC Service Module to 6.1.1.0 or later on all Windows, Linux, and ESXi hosts. Vendor-released patch: 6.1.1.0. Verify the installed version on each managed PowerEdge server after the update, since iSM is a separate host component from iDRAC firmware and is not upgraded by a firmware flash. Where the update cannot be applied immediately, the practical exposure reduction comes from tightening local administrative access on managed hosts - restrict administrator/root membership to the minimum set of operators, and audit for unnecessary local privilege - because the vulnerability cannot be reached without a prior high-privileged local foothold. No network-side workaround is identified in the available data, as the vector is local only. Full details and the per-platform update packages are listed in the Dell advisory at https://www.dell.com/support/kbdoc/en-us/000523111/dsa-2026-458-security-update-for-dell-idrac-service-module-vulnerability.

Technical ContextAI · show details

iDRAC Service Module (iSM) is a lightweight Dell host-side agent installed on PowerEdge servers running Windows, Linux, or ESXi that surfaces management data such as the OS name, lifecycle log, iDRAC SNMP alerts, and OS-to-iDRAC communication to the onboard iDRAC controller. The flaw is classified as CWE-94, Improper Control of Generation of Code, meaning code or command content is assembled from data the component does not adequately constrain before it is generated or executed. The CVSS vector AV:L/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L confirms the trigger is strictly local and requires high privileges, with no user interaction and low confidentiality, integrity, and availability impact confined to the same security scope; the sources do not describe the specific input path or interface through which the injected code is generated, so the exact trigger mechanism remains unconfirmed in the available data. Affected builds are all iSM releases below 6.1.1.0 across the three supported host operating systems.

Attack Technique

Code Injection CRITICAL

Code injection occurs when an application accepts user input and passes it directly into a language interpreter or evaluator without proper sanitization.

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
