In Lenovo Connect2 versions earlier than 4.2.5.4885 for Windows and 4.2.5.3071 for Android, when an ad-hoc connection is made between two systems for the purpose of sharing files, the password for this ad-hoc connection will be stored in a user-readable location. An attacker with read access to the user's contents could connect to the Connect2 hotspot and see the contents of files while they are being transferred between the two systems.Show less

Privilege escalation vulnerability in Lenovo Nerve Center for Windows 10 on Desktop systems (Lenovo Nerve Center for notebook systems is not affected) that could allow an attacker with local privileges on a system to alter registry keys.Show less

In Lenovo XClarity Administrator (LXCA) before 1.3.0, if service data is downloaded from LXCA, a non-administrative user may have access to password information for users that have previously authenticated to the LXCA's internal LDAP server, including administrative accounts and service accounts with administrative privileges. This is an issue only for users who have used local authentication with LXCA and not remote authentication against external LDAP or ADFS servers.Show less

In the IMM2 firmware of Lenovo System x servers, remote commands issued by LXCA or other utilities may be captured in the First Failure Data Capture (FFDC) service log if the service log is generated when that remote command is running. Captured command data may contain clear text login information. Authorized users that can capture and export FFDC service log data may have access to these remote commands.Show less

If multiple users are concurrently logged into a single system where one user is sending a command via the Lenovo ToolsCenter Advanced Settings Utility (ASU), UpdateXpress System Pack Installer (UXSPI) or Dynamic System Analysis (DSA) to a second machine, the other users may be able to see the user ID and clear text password that were used to access the second machine during the time the command is processing.Show less

Lenovo System Update (formerly ThinkVantage System Update) before 5.07.0019 allows local users to gain privileges by navigating to (1) "Click here to learn more" or (2) "View privacy policy" within the Tvsukernel.exe GUI application in the context of a temporary administrator account, aka a "local privilege escalation vulnerability."Show less

Lenovo System Update (formerly ThinkVantage System Update) before 5.07.0019 allows local users to gain privileges by making a prediction of tvsu_tmp_xxxxxXXXXX account credentials that requires knowledge of the time that this account was created, aka a "temporary administrator account vulnerability."Show less

The Jakarta Multipart parser in Apache Struts 2 2.3.x before 2.3.32 and 2.5.x before 2.5.10.1 has incorrect exception handling and error-message generation during file-upload attempts, which allows remote attackers to execute arbitrary commands via a crafted Content-Type, Content-Disposition, or Content-Length HTTP header, as exploited in the wild in March 2017 with a Content-Type header containing a #cmd= string.Show less
