Vim feedkeys() and writefile() functions shell command execution
| vim-feedkeyswritefile-command-execution (34012) |  High Risk |
Description:
Vim could allow a remote attacker to execute arbitrary commands on the system, caused by a vulnerability in the modelines feature when handling the feedkeys() and writefile() functions. An attacker could exploit this vulnerability by creating a specially-crafted file containing shell metacharacters which would allow the attacker to inject and execute arbitrary shell commands on the system with the privileges of the victim, if the attacker could persuade the victim to open the malicious file.
