Lifecycle Timeline
3DescriptionCVE.org
An arbitrary file upload vulnerability in the ueditor component of MCMS v5.4.3 allows attackers to execute arbitrary code via uploading a crafted file.
Executive ViewAI
Organizations using the ueditor component of MCMS face critical risk from CVE-2025-29287, a unrestricted file upload vulnerability rated CVSS 9.8. This could allow attackers to access or modify files outside intended directories, potentially exposing sensitive configuration or credentials. Proof-of-concept code is publicly available, increasing the risk of exploitation. Organizations should apply vendor updates immediately when available and implement compensating controls in the interim.
Apply vendor patch. If immediate patching is not feasible: (1) Restrict file upload functionality via WAF; (2) Implement allowlist-based file type validation; (3) Use chroot/containerization to limit filesystem access.

SSVC AssessmentENISA
Priority Score
Attack Technique
Malicious file upload attacks exploit insufficient validation when web applications accept user-provided files.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
