Introduction:  
By using an authenticated account, an attacker can write a payload to /goform/edit_opt, which will then be triggered when running the diagnostics (via /goform/diagnostics_doit), resulting in a buffer overflow.  
  
Vulnerability:  
When writing to options within RLM, if an input is longer than 1024 chars it will result in a buffer overflow, allowing either a secfault, crashing the program, or potentially resulting in RCE.  
  
Recommendation:  
Validate input lengths before copying into a buffer.
