CVE-2025-57205 Vulnerability Summary

CVE-2025-57205: iNiLabs School Express (SMS Express) 6.2 is affected by a Stored Cross-Site Scripting (XSS) vulnerability in the content-management features available to authenticated admin users. The vulnerability resides in POSTed editor parameters submitted to the /posts/edit/{id} endpoint (and similarly in Notice and Pages editors). Due to insufficient input sanitization and output encoding, attackers can inject HTML/JS payloads. The payload is saved and later rendered unsanitized, resulting in JavaScript execution in other users' browsers when they access the affected content. This issue allows an authenticated attacker to execute arbitrary JavaScript in the context of another user, potentially leading to session hijacking, privilege escalation, data exfiltration, or administrative account takeover. The application does not enforce a restrictive Content Security Policy (CSP) or adequate filtering to prevent such attacks.

Assessing the Risk of CVE-2025-57205

Access Complexity Graph

The exploitability of CVE-2025-57205 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2025-57205

No exploitability data is available for CVE-2025-57205.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2025-57205, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis

Below is the Impact Analysis for CVE-2025-57205, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
