UltraEdit uses weak encryption to record FTP passwords in the uedit32.ini file, which allows local users who can read the file to decrypt the passwords and gain privileges.

Untrusted search path vulnerability in IDM Computer Solutions UltraEdit 16.20.0.1009, 16.10.0.1036, and probably other versions allows local users, and possibly remote attackers, to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse dwmapi.dll that is located in the same folder as a bin, cpp, css, c, dat, hpp, html, h, ini, java, log, mak, php, prj, txt, or xml file.
