AV:L/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H
Local vector with an existing low-priv foothold (PR:L) and required admin execution (UI:R); planted library runs in the privileged update process, crossing authority (S:C) for full C/I/A code execution.

Dell Server Update Utility, versions prior to 26.07.01, contains an Uncontrolled Search Path Element vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Code execution.
Articles & Coverage 2
AnalysisAI
Code execution can be achieved through an uncontrolled search path in Dell Server Update Utility (SUU) and its bundled Driver Packs for Windows and Linux at all versions prior to 26.07.01, which load libraries from locations an attacker may be able to control (CWE-427). Exploitation is local and not remotely reachable: per the CVSS vector (AV:L/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H) an attacker must already hold low-privileged local access, must be able to plant a malicious library in a directory the utility searches, and must wait for a higher-privileged user or administrator to subsequently run SUU so the planted code loads with that user's privileges. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to already have low-privileged local access to a system where Dell Server Update Utility (or the bundled Driver Pack) prior to 26.07.01 is installed, and the ability to write a malicious library into a directory that the utility searches when resolving dependencies. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a locally-exploitable code-execution flaw, not a remotely-wormable one. … 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: 26.07.01 - Dell has published DSA-2026-422 (https://www.dell.com/support/kbdoc/en-us/000509930/dsa-2026-422-security-update-for-dell-server-update-utility-suu-vulnerability) and users of Server Update Utility or the bundled Driver Packs for Windows/Linux should upgrade every installed instance from any version below 26.07.01 to 26.07.01 or later. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all instances of Dell Server Update Utility (SUU) and bundled Driver Packs for Windows and Linux to identify versions prior to 26.07.01, and restrict local write access to directories searched by SUU where feasible. …
