[原文]** DISPUTED ** Blackboard Academic Suite 6.0 and earlier does not properly clear session information when de-authenticating a user who is idle, which allows subsequent users to log in as the previous user and gain privileges. NOTE: the vendor has disputed this issue, saying that "This is a customer specific issue related to their Kerberos authentication single sign-on application and not a vulnerability in the Blackboard product."


[CNNVD]Blackboard 学习系统访问确认漏洞(CNNVD-200602-008)

        ** 存在争议 ** Blackboard Academic Suite 6.0及之前版本在对空闲用户取消身份验证时没有正确清除线程信息。这就使得后续用户能够以之前用户的身份登录并获取权限。注意:厂商对这一问题提出质疑,并说"这是特定于客户的问题,与他们的Kerberos身份验证单一登录应用程序有关,不属于 Blackboard 产品的漏洞。"

28023
Blackboard Academic Suite Local Session Deauthentication
Remote / Network Access Authentication Management
Loss of Integrity

- 漏洞描述

Blackboard Academic Suite has been reported to contain a flaw that may allow a remote attacker to gain access to arbitrary user accounts. The issue is reportedly due to the program not properly clearing session information when de-authenticating a user who is idle, allowing a subsequent user to log in as the previous user without re-authenticating. The vendor has disputed this issue saying "This is a customer specific issue related to their Kerberos authentication single sign-on application and not a vulnerability in the Blackboard product."
