Vulnerability Assessment

Weakness	CWE CWE-284 OWASP Top 10:2025 A01:2025 - Broken Access Control ASVS 5.0 V8 - Authorization Access control enforcement MITRE ATT&CK 1 technique across 1 tactic: Defense Evasion The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. Sign in to read
Exploitation Conditions	The upload script /assets/uploadSllyabus.php must be accessible (default configuration). No authentication is required (CVSS PR:N). The attacker only needs network access to the endpoint. Limits: the uploaded file must be in a web-accessible directory, and PHP must be enabled for execution in that directory. The exploit relies on the attacker knowing or guessing the upload path.
Impact	CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L) suggests low impact, but the description's 'unrestricted upload' often implies code execution, creating a disconnect. EPSS probability is very low (0.06%), and there is no CISA KEV listing. Public exploit code exists, increasing risk for internet-facing instances. Overall risk is moderate-impact may be higher than CVSS indicates, but active exploitation appears rare. No conflicting data on authentication or attack vector.
Exploit ScenarioDerived	An attacker sends a crafted HTTP POST request to /assets/uploadSllyabus.php with a PHP web shell as the File parameter. The server accepts the file without validation, allowing the attacker to access the uploaded shell at a predictable URL and execute arbitrary commands on the server. A public exploit is available.

AnalysisAIv1 – Jul 27, 2026

Unrestricted file upload in Oranbyte School Management System allows remote attackers to upload arbitrary files, including PHP shells, to the server via the /assets/uploadSllyabus.php endpoint. The vulnerability requires no authentication and has a publicly available exploit, but the low EPSS score (0.06%) suggests limited active exploitation. Attackers can achieve code execution if the uploaded file is accessible and executable.

RemediationAI

No official patched version is available due to the rolling release model. As a workaround, restrict file uploads to allowed extensions (e.g., images only), move the upload directory outside the web root, disable PHP execution in the upload directory via .htaccess (e.g., 'php_flag engine off'), or implement authentication for the upload endpoint. These mitigations may break legitimate upload functionality. Monitor the project repository for a fix addressing the commit hash.

Technical ContextAI · show details

The vulnerability resides in a PHP-based school management system (Oranbyte, version 1.0 per CPE) using a rolling release model. The file /assets/uploadSllyabus.php processes file uploads without proper validation of the File argument, leading to unrestricted upload (CWE-284: Improper Access Control). This class of vulnerability in PHP applications typically allows remote code execution if uploaded files can be executed in the web context.
