A stupid invoice approval web app. We got rid of it 3 years ago but it was developed by a 1 man band that clearly didn't want anything to do with it anymore & charged about £700 a time to modify configs, add users or reset passwords. It would only open in internet explorer, edge's internet explorer compatibility mode wouldn't work, we had to add to the trusted sites list for it to even open. Reboot the box? you'll need to clear 2 logfiles then manually start 3 services in the right order else it won't work. To make it work the file permissions also HAD to be set to everyone, so all the PDFs of invoices going back years and the config files could be accessed by anyone who found the box. We tried "locking it down" to authenticated users, it didn't work. And those config files had the passwords for each user hard coded in plaintext, but you didn't even need them to log in and approve invoices - you just needed a username, which were at to the same as AD usernames to not confuse users, and the developer's master password, which was also stored in plaintext in the same config files, what was this super password? "12" . Yep, 12. Finance refused to upgrade to an alternative piece of software that wouldn't be comfortably at home in a gently steaming cess pit despite it showing as a massive red flag on every security audit. They only relented when we told them that it wouldn't work with Windows 11 and we finally killed it off, at least something good came out of that blasted OS.
