Name of the Vulnerable Software and Affected Versions Chamilo LMS versions prior to 1.11.38 and prior to 2.0.0-RC.3

Description Chamilo LMS generates REST API keys using a predictable formula: md5(time() + (user id * 5) - rand(10000, 10000)). The rand(10000, 10000) function consistently returns 10000, simplifying the key generation to md5(timestamp + user id * 5 - 10000). Knowing a username and approximate key creation time allows an attacker to brute-force the API key.

Recommendations Update to version 1.11.38 or later. Update to version 2.0.0-RC.3 or later.

Fix

Use of Insufficiently Random Values
