DescriptionCVE.org

A vulnerability was determined in diem-project diem up to 5.1.3. This affects the function executeCommand of the file dmAdminPlugin/modules/dmConsole/actions/actions.class.php of the component dmConsole. This manipulation of the argument dm_command causes cross-site request forgery. The attack may be initiated remotely. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through an issue report but has not responded yet.

AnalysisAI

Cross-site request forgery in diem-project/diem up to version 5.1.3 allows remote attackers to trigger unauthorized console command execution by tricking an authenticated administrator into visiting a malicious page. The vulnerability resides in the dmConsole module's executeCommand action, which processes the dm_command parameter without verifying request origin. …

Vulnerability AssessmentAI

Exploitation Exploitation requires that: (1) the dmAdminPlugin with the dmConsole module is installed and accessible - this is a plugin component, not guaranteed in all Diem deployments; (2) a Diem administrator is actively authenticated in a browser session; and (3) the administrator can be lured to visit attacker-controlled web content (UI:P). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 2.1 (AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:N) accurately reflects the constrained real-world risk: exploitation is gated on user interaction (UI:P), meaning a victim admin must actively visit attacker-controlled content, and the reported integrity impact is classified as low. … 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 No vendor-released patch has been identified at time of analysis; the vendor has not responded to the disclosure. … Detailed patch versions, workarounds, and compensating controls in full report.
