This Metasploit module exploits a vulnerability found in Uptime version 7.4.0 and 7.5.0. The vulnerability began as a classic arbitrary file upload vulnerability in post2file.php, which can be exploited by exploits/multi/http/uptime_file_upload_1.rb, but it was mitigated by the vendor. Although the mitigation in place will prevent uptime_file_upload_1.rb from working, it can still be bypassed and gain privilege escalation, and allows the attacker to upload file again, and execute arbitrary commands.
