DescriptionCVE.org

A vulnerability has been identified in Mendix Studio Pro 10.11 (All versions), Mendix Studio Pro 10.12 (All versions), Mendix Studio Pro 10.13 (All versions), Mendix Studio Pro 10.14 (All versions), Mendix Studio Pro 10.15 (All versions), Mendix Studio Pro 10.16 (All versions), Mendix Studio Pro 10.17 (All versions), Mendix Studio Pro 10.18 (All versions), Mendix Studio Pro 10.19 (All versions), Mendix Studio Pro 10.20 (All versions), Mendix Studio Pro 10.21 (All versions), Mendix Studio Pro 10.22 (All versions), Mendix Studio Pro 10.23 (All versions), Mendix Studio Pro 10.24 (All versions < V10.24.21), Mendix Studio Pro 11.0 (All versions), Mendix Studio Pro 11.1 (All versions), Mendix Studio Pro 11.10 (All versions), Mendix Studio Pro 11.11 (All versions), Mendix Studio Pro 11.2 (All versions), Mendix Studio Pro 11.3 (All versions), Mendix Studio Pro 11.4 (All versions), Mendix Studio Pro 11.5 (All versions), Mendix Studio Pro 11.6 (All versions < V11.6.7), Mendix Studio Pro 11.7 (All versions), Mendix Studio Pro 11.8 (All versions), Mendix Studio Pro 11.9 (All versions). Affected versions of Mendix Studio Pro do not properly validate or sanitize project files processed during the build pipeline. This could allow an attacker who tricks a user into opening and running a specially crafted malicious project locally on their system to execute arbitrary code in the context of that user.

AnalysisAI

Code injection via malicious project files in Mendix Studio Pro 10.11 through 11.11 allows arbitrary code execution on a developer's workstation when a victim opens and runs a specially crafted project through the build pipeline. Siemens' own ProductCERT (SSA-779310) reported this flaw, classifying it under CWE-94, with patches available only for the 10.24 and 11.6 long-term support lines. …

Attack ChainAIDerived

Hypothetical attack flow derived from CVE metadata

Access
Craft malicious Mendix project file
Delivery
Deliver via social engineering or repository poisoning
Exploit
Victim opens project in Studio Pro
Execution
Victim initiates build pipeline
Persist
Unsanitized project content triggers code injection
Impact
Arbitrary code executes as victim user

Vulnerability AssessmentAI

Exploitation Exploitation requires that the victim developer opens a specially crafted malicious Mendix project file within the affected IDE and initiates a build pipeline execution - both actions are required (open AND run). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS base score of 5.4 (AV:N/AC:H/PR:H/UI:R/S:C/C:N/I:H/A:N) is notably inconsistent with the described attack scenario in several ways. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker with knowledge of Mendix project file structure crafts a malicious .mpr or associated project artifact containing injected code payloads that execute during the build pipeline. The attacker distributes this project via a spoofed collaboration invite, a typosquatted repository, or a poisoned dependency shared in a developer forum. …
Remediation Upgrade to Mendix Studio Pro V10.24.21 or later if on the 10.x release track, or to V11.6.7 or later if on the 11.6 branch, as per the Siemens ProductCERT advisory SSA-779310 (https://cert-portal.siemens.com/productcert/html/ssa-779310.html). … Detailed patch versions, workarounds, and compensating controls in full report.

Threat intelligence, references, and detailed analysis are available after sign-in.
