A user's unique identifier, UDCID, is leaked via a cookie and it could lead to account compromise if this identifier is captured or otherwise known, in the case tested the UDCID was known to be the institutional ID printed on ID cards. The UDCID could be used to exploit a race condition that would provide an attacker with unauthorized access. For a student, the attacker could drop them from their courses, reject financial aid, change their personal information, etc. For a professor, this could lead to an inability to manage their courses, allow a malicious student to put in false final grades, etc. For an administrator, an attacker could change users information, place false holds on student accounts, etc.
