Affected softwaremingsoft MCMS
Severity9.8 Critical CVSS 3.0 2 scores
WeaknessUnrestricted file upload (CWE-434)

Description

An issue was discovered in com\mingsoft\basic\action\web\FileAction.java in MCMS 4.6.5. Since the upload interface does not verify the user login status, you can use this interface to upload files without setting a cookie. First, start an upload of JSP code with a .png filename, and then intercept the data packet. In the name parameter, change the suffix to jsp. In the response, the server returns the storage path of the file, which can be accessed to execute arbitrary JSP code.

Waratek protection

Outside Waratek scope

A Java vulnerability, but not one Waratek protects. It affects only Java on a user's desktop (applets, Web Start, JavaFX, the installer), sits in a product the Waratek agent can't be installed into, or is in a package we don't expect in business applications. The decision below says which.

  • Protection none
  • Action not pursued none
  • Review automated Upstream data
  • Record active
Decided by An OSV.dev record of this CVE affecting a package published to Maven Central. When every such package is one business applications do not use (Minecraft mods and launchers, Fastjson) and no tracked product is named by CPE, it settles the CVE as Outside Waratek scope instead
Finding Every Maven package this CVE affects (net.mingsoft:ms-mcms) is on the excluded_maven_packages list in known-products.yaml, so it is not reviewed.
