Julien Ahrens has discovered a vulnerability in Ricoh DC Software DL-10, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error in the SR10 FTP server when logging FTP commands. This can be exploited to cause a stack-based buffer overflow via e.g. an overly long "USER" FTP command.
Successful exploitation allows execution of arbitrary code, but requires the "Log file name" option to be enabled (disabled by default).
The vulnerability is confirmed in version 18.104.22.168 (SR10.exe 22.214.171.124). Other versions may also be affected.
Solution: Restrict access to trusted hosts only or disable the "Log file name" option.
