Dell PowerProtect One, versions 20.1.0.0 and below, contain a Reliance on Insufficiently Trustworthy Component vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to Cache poisoning.
AnalysisAI
Cache poisoning in Dell PowerProtect One versions 20.1.0.0 and below exposes environments to integrity violations via an insufficiently trustworthy component (CWE-1357), allowing a remote unauthenticated attacker to inject malicious data into the system cache when user interaction occurs. The CVSS vector (AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:H/A:N) scores 5.3 Medium, with high attack complexity and mandatory user interaction substantially constraining real-world exploitability despite the network-accessible entry point. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires network-level access to a Dell PowerProtect One instance running version 20.1.0.0 or earlier, a high-complexity attack setup (AC:H per CVSS), and a victim user performing some interaction with the system (UI:R per CVSS) - the specific user action required is not detailed in available data. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 5.3 Medium reflects a moderately constrained risk profile. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with network access and the ability to engineer high-complexity conditions targets a user interacting with a Dell PowerProtect One appliance, manipulating an insufficiently trustworthy component to inject attacker-controlled data into the cache. Subsequent reads from that cache by the system or other users return the poisoned entries, potentially causing integrity violations such as corrupted backup metadata, malicious redirect responses, or tampered configuration data. … |
| Remediation | Upgrade Dell PowerProtect One to a version beyond 20.1.0.0 per Dell advisory DSA-2026-369 (https://www.dell.com/support/kbdoc/en-us/000500902/dsa-2026-369-security-update-for-dell-powerprotect-one-multiple-vulnerabilities); the precise patched release number must be obtained directly from the advisory, as it was not included in the available data. … Detailed patch versions, workarounds, and compensating controls in full report. |
