This is a target with direct implementation of the CVE-2019-14813 for ghostscript 9.26a and is here to assist in developing exploits for this vulnerability.

Description

A flaw was found in ghostscript, versions 9.x before 9.28, in the setsystemparams procedure where it did not properly secure its privileged calls, enabling scripts to bypass -dSAFER restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands.

Environment details

The system is accessible at 10.0.200.13 and runs gs -sDEVICE=ppmraw -dSAFER on port 12345/tcp.

Flags can be found at:

  • /root/ETSCTF
  • /etc/passwd gecos
  • /etc/shadow password hash
  • env variable
