Problem Statements

1. CVE-2014-0226 (100 points)

Bug Overview:

Race condition in the mod_status module in the Apache HTTP Server before 2.4.10 allows remote attackers to cause a denial of service (heap-based buffer overflow), or possibly obtain sensitive credential information or execute arbitrary code, via a crafted request that triggers improper scoreboard handling within the status_handler function in modules/generators/mod_status.c and the lua_ap_scoreboard_worker function in modules/lua/lua_request.c.

  • Aim: Write a working exploit for this CVE.
  • Install vulnerable service in a VM/Docker and ensure to meet the condition so that you can exploit it.
  • Run your exploit on the vulnerable service and make a video of it.
  • Write a brief report about this bug including your exploit code and link for exploit and Video proof.

2. CVE-2017-12615 (100 points)

Bug Overview:

When running Apache Tomcat 7.0.0 to 7.0.79 on Windows with HTTP PUTs enabled (e.g. via setting the read-only initialisation parameter of the Default to false) it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server. That could lead to remote code execution on the server.

  • Aim: Write a working exploit for this CVE by which you can achieve RCE on local VM/Docker.
  • Install vulnerable service in a VM/Docker and ensure to meet the condition so that you can exploit it.
  • Run your exploit on the vulnerable service and make a video of it.
  • Write a brief report about this bug including your exploit code and link for exploit and Video proof.

3. CVE-2020-0609 and CVE-2020-0610 (200 points)

Bug Overview:

Specially crafted requests lead to DoS/RCE without any user interaction on Windows RDP service.

  • Aim: Setup a local Vm in which to install vulnerable windows RDP service and write an exploit that could lead to DoS/RCE on the local VM server.
  • Write a brief report about this bug including your exploit code and link for exploit and Video proof.

4. CVE-2018-1335 (100 points)

Bug Overview:

This bug leads to command injection vulnerability in Apache Tika -server 1.18 and uses Cscript.exe to execute Jscript or VBS code and run arbitrary commands.

  • Aim: Write a working exploit for this CVE by which you can achieve RCE on the local VM.
  • Install vulnerable service in a VM and ensure to meet the condition so that you can exploit it.
  • Run your exploit on the vulnerable service and make a video of it.
  • Write a brief report about this bug including your exploit code and link for exploit and Video proof.

5. CVE-2019-0232 (100 points)

Bug Overview:

Apache Tomcat has a vulnerability in the CGI Servlet which can be exploited to achieve remote code execution (RCE). This is only exploitable when running on Windows in a non-default configuration in conjunction with batch files.

  • Aim: Write a working exploit by which you can achieve RCE on the local VM.
  • Install vulnerable service in a VM and ensure to meet the condition so that you can exploit it.
  • Run your exploit on the vulnerable service and make a video of it.
  • Write a brief report about this bug including your exploit code and link for exploit and Video proof.
