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

Privilege Escalation in Lenovo XClarity Administrator earlier than 1.2.0, if LXCA is used to manage rack switches or chassis with embedded input/output modules (IOMs), certain log files viewable by authenticated users may contain passwords for internal administrative LXCA accounts with temporary passwords that are used internally by LXCA code.Show less

A Denial of Service in Intel Ethernet Controller's X710/XL710 with Non-Volatile Memory Images before version 5.05 allows a remote attacker to stop the controller from processing network traffic working under certain network use conditions.Show less

A vulnerability has been identified in a signed kernel driver for the BIOS of some ThinkPad systems that can allow an attacker with Windows administrator-level privileges to call System Management Mode (SMM) services. This could lead to a denial of service attack or allow certain BIOS variables or settings to be altered (such as boot sequence). The setting or changing of BIOS passwords is not affected by this vulnerability.Show less

A vulnerability has been identified in some Lenovo Notebook and ThinkServer systems where an attacker with administrative privileges on a system could install a program that circumvents Intel Management Engine (ME) protections. This could result in a denial of service or privilege escalation attack on the system.Show less

During an internal security review, Lenovo identified a local privilege escalation vulnerability in Lenovo System Interface Foundation software installed on some Windows 10 PCs where a user with local privileges could run arbitrary code with administrator level privileges.Show less

The BIOS for Lenovo ThinkCentre E93, M6500t/s, M6600, M6600q, M6600t/s, M73p, M800, M83, M8500t/s, M8600t/s, M900, M93, and M93P devices; ThinkServer RQ940, RS140, TS140, TS240, TS440, and TS540 devices; and ThinkStation E32, P300, and P310 devices might allow local users or physically proximate attackers to bypass the Secure Boot protection mechanism by leveraging an AMI test key.Show less

The firmware in Lenovo Ultraslim dongles, as used with Lenovo Liteon SK-8861, Ultraslim Wireless, and Silver Silk keyboards and Liteon ZTM600 and Ultraslim Wireless mice, does not enforce incrementing AES counters, which allows remote attackers to inject encrypted keyboard input into the system by leveraging proximity to the dongle, aka a "KeyJack injection attack."Show less
