CVE-2026-91909 Dell CVE debrief

Who should care

Defenders responsible for Dell OpenManage Enterprise systems, particularly those with low-privileged users and adjacent network access, should assess potential exposure and prioritize verification and mitigation efforts.

Why it matters

CVE-2026-91909 is a medium-severity vulnerability in Dell OpenManage Enterprise that could allow low-privileged attackers with adjacent network access to execute commands. Defenders should prioritize verifying exposure, assessing potential impact, and mitigating the vulnerability to prevent potential exploitation.

• Potential command execution by low-privileged attackers with adjacent network access
• Need to verify exposure and assess potential impact on Dell OpenManage Enterprise systems
• Prioritize patching or mitigating vulnerability to prevent potential exploitation

Technical summary

The vulnerability exists in Dell OpenManage Enterprise versions prior to 4.8.0, allowing a low-privileged attacker with adjacent network access to potentially execute commands due to improper neutralization of argument delimiters. This vulnerability could lead to command execution, allowing attackers to gain unauthorized access to sensitive data or disrupt system operations. Defenders should prioritize verifying exposure and assessing potential impact to prevent potential exploitation. The vulnerability's technical details are limited, but it is essential to address it promptly to prevent potential exploitation.

Defensive priority

Defenders should prioritize verifying exposure and assessing potential impact, focusing on systems with adjacent network access.

Recommended defensive actions

• Verify if Dell OpenManage Enterprise versions prior to 4.8.0 are in use and assess potential exposure
• Review network access controls to limit adjacent network access to low-privileged users
• Monitor system logs for potential command execution attempts
• Apply vendor patches or updates to affected systems
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented

Evidence notes

The CVE record and NVD entry provide limited information about the vulnerability and its potential impact. Dell's security update documentation may offer additional details.
