How the CVE Works
CVE-2025-21542 is a security flaw in Oracle Communications Order and Service Management (versions 7.4.0, 7.4.1, 7.5.0) that allows a low-privileged attacker with network access via HTTP to manipulate data. The vulnerability stems from improper access controls in the Security component, enabling unauthorized data modification (insert/update/delete), partial data exposure, and partial denial of service (DoS). The CVSS 3.1 score of 6.3 reflects its moderate risk, combining confidentiality, integrity, and availability impacts. Attackers exploit this by sending crafted HTTP requests to vulnerable endpoints, bypassing intended restrictions.
