Description

Chamilo LMS is a learning management system. Prior to version 1.11.34, there is an unauthenticated SQL injection vulnerability which allows remote attackers to execute arbitrary SQL commands via the custom_dates parameter. By chaining this with a predictable legacy password reset mechanism, an attacker can achieve full administrative account takeover without any prior credentials. The vulnerability also exposes the entire database, including PII and system configurations. This issue has been patched in version 1.11.34.

Techniques & Countermeasures

CWE-89•Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
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.
