Deeper analysis

Online Exam Mastering System version 1.0 contains a SQL injection vulnerability tracked as CVE-2025-25914. The flaw resides in the fid parameter and is classified under CWE-89, enabling unauthenticated remote code execution. It received a CVSS 3.1 score of 9.8, reflecting network attack vector, low complexity, and full impact on confidentiality, integrity, and availability.

An attacker with no credentials can send a crafted request containing malicious SQL to the vulnerable parameter, resulting in arbitrary code execution on the underlying server. Because the vulnerability requires no user interaction or authentication, it can be exploited directly over the internet by any remote party.

The single available reference is a public GitHub proof-of-concept that demonstrates the injection but supplies no official patch or mitigation guidance. EPSS scores for the CVE rose from a low baseline to a recorded peak of 0.0305 before settling at the current value of 0.0180, indicating a measurable increase in exploitation interest after disclosure.
