DescriptionCVE.org

BurgerEditor 3.2.0 through 3.4.0 contains an issue with unrestricted upload of file with dangerous type. If this vulnerability is exploited, an arbitrary file may be uploaded by an attacker who can log in to the product, potentially allowing arbitrary PHP code to be executed may be caused.

AnalysisAI

Authenticated remote code execution is possible in BurgerEditor versions 3.2.0-3.4.0 (and 2.28.0-2.30.0 per EUVD data) via unrestricted file upload, allowing a logged-in attacker to upload arbitrary PHP files and execute server-side code. The vulnerability stems from insufficient validation of uploaded file types (CWE-434), enabling placement of attacker-controlled executables in a web-accessible location. …

Vulnerability AssessmentAI

Exploitation Exploitation requires an authenticated session with high-privilege access to BurgerEditor (PR:H per CVSS 4.0 vector), meaning an attacker must first possess or acquire valid credentials for a privileged account. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 8.5 with PR:H accurately reflects that authentication is a meaningful barrier - exploitation is limited to users who can log in with elevated privileges. … 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 Apply the vendor-released patch per the official D-Zero advisory at https://burger.d-zero.co.jp/blogs/archives/3; the exact fixed version should be confirmed against that page, as the input data does not specify a precise patched release number. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: inventory all BurgerEditor deployments and confirm affected versions (3.2.0-3.4.0 or 2.28.0-2.30.0); audit recent file uploads for suspicious PHP or executable files and review access logs for anomalous upload activity. …
