CVE-2016-9488: Manageengine Applications Manager: SQL injection
CVE-2016-9488 is rated critical with a CVSS v3.0 base score of 9.8 and affects Manageengine Applications Manager. Per its scoring, it can be exploited over the network, without authentication, without any user interaction. The scored impact on confidentiality, integrity and availability is the highest available.
Vulnerability description
ManageEngine Applications Manager versions 12 and 13 before build 13200 suffer from remote SQL injection vulnerabilities. An unauthenticated attacker is able to access the URL /servlet/MenuHandlerServlet, which is vulnerable to SQL injection. The attacker could extract users' password hashes, which are MD5 hashes without salt, and, depending on the database type and its configuration, could also execute operating system commands using SQL queries.

- Privileges required: None. No account or prior access is needed.
- User interaction: None. No action from any user is needed.
- Scope: Unchanged. Impact stays within the vulnerable component.
- Confidentiality impact: High. Total loss of confidentiality; sensitive data can be fully disclosed.

Underlying weakness
CWE-89: Improper Neutralization of Special Elements used in an SQL Command
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
