CVE-2013-2080

CVE-2013-2080: Moodle is vulnerable to Sensitive Information Disclosure

The core_grade component in Moodle through 2.2.10, 2.3.x before 2.3.7, and 2.4.x before 2.4.4 does not properly consider the existence of hidden grades, which allows remote authenticated users to obtain sensitive information by leveraging the student role and reading the Gradebook Overview report.

Root Cause Analysis

The vulnerability stems from incorrect handling of hidden grade visibility in multi-course contexts. The commit diff shows:

In grade/report/lib.php, the blank_hidden_total() function originally used a scalar value ($this->showtotalsifcontainhidden) to control visibility. The patch changed this to an array keyed by course ID ($this->showtotalsifcontainhidden[$courseid]).
The pre-patch implementation would use the same visibility setting across all courses when calculating totals, failing to respect per-course configurations. This allowed students to see hidden grade information if any course in their overview had lenient visibility settings.
The overview report constructor in grade/report/overview/lib.php was also modified to initialize showtotalsifcontainhidden as an array per course, confirming the scalar approach was vulnerable. The blank_hidden_total() function is the direct point where hidden grade calculations occurred, making it the primary vulnerable function.
