Original Release date: 16 Nov 2012 | Last revised: 16 Nov 2012

Overview

Novell File Reporter 1.0.2 contains multiple vulnerabilities including a heap overflow, arbitrary file retrieval, and arbitrary file upload.

Description

The Rapid7 advisory states:

    CVE-2012-4956 - Heap Overflow
    When handling requests of name "SRS", the NFRAgent.exe fails to generate a response in a secure way, copying user controlled data into a fixed-length buffer in the heap without bounds checking. This vulnerability can result in remote code execution under the context of the SYSTEM account.

    CVE-2012-4957 - Arbitrary File Retrieval
    When handling requests on "/FSF/CMD" for records with NAME "SRS", OPERATION "4" and CMD "103" the NFRAgent.exe allows a remote unauthenticated user to retrieve arbitrary remote files, specified with the tag "PATH", with SYSTEM privileges.

    CVE-2012-4958 - Arbitrary File Retrieval
    When handling requests on "/FSF/CMD" for records with NAME "FSFUI" and UICMD "126" the NFRAgent.exe allows a remote unauthenticated user to retrieve arbitrary remote text files, specified with the tag "FILE", with SYSTEM privileges.

    CVE-2012-4959 - Arbitrary File Upload
    When handling requests on "/FSF/CMD" for records with NAME "FSFUI" and UICMD "130" the NFRAgent.exe allows a remote unauthenticated user to upload files to the host, specified with the tag "FILE", with SYSTEM privileges. It allows to execute remote code with SYSTEM privileges.
