Predictable password-recovery tokens vulnerability in Moodle

CVE-2015-5267 · MEDIUM Severity

AV:N/AC:L/AU:N/C:P/I:N/A:N

lib/moodlelib.php in Moodle through 2.6.11, 2.7.x before 2.7.10, 2.8.x before 2.8.8, and 2.9.x before 2.9.2 relies on the PHP mt_rand function to implement the random_string and complex_random_string functions, which makes it easier for remote attackers to predict password-recovery tokens via a brute-force approach.
