pyftpd is prone to multiple default-account vulnerabilities. These
issues stem from a design flaw that makes several accounts available
to remote attackers.
Successful exploits allow remote attackers to gain unauthorized access
to a vulnerable application.
2.
pyftpd creates temporary files in an insecure manner.
An attacker with local access could potentially exploit this issue to
perform symbolic-link attacks, overwriting arbitrary files in the
context of the affected application.
Successfully mounting a symlink attack may allow the attacker to
delete or corrupt sensitive files, which may result in a denial of
service. Other attacks may also be possible.");
