AI Analysis

Impact

A flaw in the /business/qnaire/upload.jsp component of the MetaCRM application allows attackers to manipulate the File parameter for unrestricted file upload; the CVE description does not explicitly state that uploaded files are executed, but the absence of validation is inferred to enable potential execution of malicious code, which could lead to remote code execution or other integrity and confidentiality violations.

Affected Systems

The vulnerable logic exists in Metasoft 美特软件 MetaCRM versions up to 6.4.0 Beta06. Any installation running one of these releases and exposing the upload.jsp endpoint is considered at risk; no specific build numbers are provided.

Risk and Exploitability

The CVSS score of 6.9 denotes a moderate severity, while the EPSS score of less than 1% indicates a low likelihood of widespread exploitation in the wild. However, a publicly available exploit is known and the attack can be launched remotely from the web interface without privileged context. The vulnerability is not listed in the CISA KEV catalog, but the lack of a vendor response suggests that the working‑path for remediation may remain unpatched for some time.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade MetaCRM to a release newer than 6.4.0 Beta06; if no patch exists, move to a current stable version that removes the upload.jsp flaw.
  • As a temporary measure, configure the application or web server so that only safe file types are accepted on the upload.jsp endpoint and enforce strict maximum file size limits; ensure the upload directory has no execute permissions.
  • If the upload functionality is not required for business operations, disable or block access to upload.jsp, or otherwise place it behind strong authentication and additional input validation controls.
