Original Bulletin: 

Comment: Proof of concept is publicly available for this vulnerability and
         there is no known fix. This US-CERT bulletin contains a suggested
         workaround. In addition, NFRAgent.exe uses port 3037/TCP therefore
         blocking this port on the Enterprise border is recommended.

Vulnerability Note VU#273371

Novell File Reporter contains multiple vulnerabilities

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

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

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

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.

Additional details may be found in the Rapid7 blog post entitled "New 0day
Exploits: Novell File Reporter Vulnerabilities".

A remote unauthenticated attacker may be able to execute code, retrieve
arbitrary files, and upload arbitrary files to the host.

We are currently unaware of a practical solution to this problem. Please
consider the following workaround.

Restrict Access

Deploy appropriate firewall rules so only trusted networks and hosts can
communicate with the Novell File Reporter agent.
