Document Title: =============== Stanford University - Multiple SQL Injection Vulnerabilities References (Source): ==================== http://www.vulnerability-lab.com/get_content.php?id=1829 Release Date: ============= 2016-05-09 Vulnerability Laboratory ID (VL-ID): ==================================== 1829 Common Vulnerability Scoring System: ==================================== 7.8 Product & Service Introduction: =============================== Stanford University, located between San Francisco and San Jose in the heart of California's Silicon Valley, is one of the world's leading teaching and research universities. Since its opening in 1891, Stanford has been dedicated to finding solutions to big challenges and to preparing students for leadership in a complex world.

The vulnerability allows remote attackers and privileged user accounts to execute own sql commands to compromise the web-server or dbms. The vulnerability is located in the `id` value of the `getevent.php` file GET method request. Remote attackers are able to execute own malicious sql commands via id value to compromise the web-server or connected database management system. The issue is a classic remote sql injection vulnerability. The request method to execute is GET and the attack vector is located on the application-side of the active web-service. The security risk of the sql-injection vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 7.8. Exploitation of the remote sql injection web vulnerability requires no user interaction and a low privileged web-application user account. Successful exploitation of the remote sql injection results in database management system, web-server and web-application compromise. Request Method(s): [+] GET Vulnerable File(s): [+] getevent.php Vulnerable Parameter(s): [+ id Proof of Concept (PoC): ======================= The sql-injection vulnerability can be exploited by remote attackers without privileged user account or user interaction.
