Detailsinfo

A vulnerability classified as critical has been found in vworld4u office-converter up to 1.0.2. Affected is the function generatePdf/generateHtml of the component File Name Handler. The manipulation of the argument fileName with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

office-converter through 1.0.2 contains an OS command injection vulnerability that allows attackers to execute commands by supplying a crafted fileName to generatePdf() or generateHtml(). Attackers can embed $(...), backticks, or a closing quote with shell metacharacters in the file name, which is concatenated into an unoconv command run via child_process.exec(), executing commands with Node.js process privileges.
