How the CVE Works
CVE-2025-1833 is a critical Server-Side Request Forgery (SSRF) vulnerability in zzERP (versions up to 2024-8). The flaw resides in the `sendNotice` function within Customer_noticeAction.java, where improper validation of the `url` parameter allows attackers to craft malicious HTTP requests. By manipulating this parameter, an attacker can force the server to send unauthorized requests to internal or external systems, potentially accessing sensitive data, bypassing firewalls, or escalating attacks to other internal services. The vulnerability is remotely exploitable without authentication, increasing its severity.
