A DLL search path vulnerability could allow privilege escalation in some Lenovo installation packages, prior to version 1.2.9.3, during installation if an attacker already has administrative privileges.

A potential vulnerability in the SMI callback function used in Legacy USB driver using passed parameter without sufficient checking in some Lenovo ThinkPad models may allow arbitrary code execution.

A vulnerability was reported in various BIOS versions of older ThinkPad systems that could allow a user with administrative privileges or physical access the ability to update the Embedded Controller with unsigned firmware.

A potential vulnerability in the SMI callback function used in the Legacy USB driver using boot services structure in runtime phase in some Lenovo ThinkPad models may allow arbitrary code execution.

A vulnerability reported in Lenovo Service Bridge before version 4.1.0.1 could allow unencrypted downloads over FTP.

A vulnerability reported in Lenovo Service Bridge before version 4.1.0.1 could allow remote code execution.

A vulnerability reported in Lenovo Service Bridge before version 4.1.0.1 could allow remote code execution.

A vulnerability reported in Lenovo Service Bridge before version 4.1.0.1 could allow cross-site request forgery.

A DLL search path vulnerability was reported in PaperDisplay Hotkey Service version 1.2.0.8 that could allow privilege escalation. Lenovo has ended support for PaperDisplay Hotkey software as the Night light feature introduced in Windows 10 Build 1703 provides similar features.

A denial of service vulnerability was reported in Lenovo System Update before version 5.07.0084 that could allow service log files to be written to non-standard locations.

An internal product security audit discovered a session handling vulnerability in the web interface of ThinkAgile CP-SB (Storage Block) BMC in firmware versions prior to 1908.M. This vulnerability allows session IDs to be reused, which could provide unauthorized access to the BMC under certain circumstances. This vulnerability does not affect ThinkSystem XCC, System x IMM2, or other BMCs.

A vulnerability in various versions of Iomega and LenovoEMC NAS products could allow an unauthenticated user to access files on NAS shares via the API.

A stored cross-site scripting (XSS) vulnerability exists in various firmware versions of the legacy IBM System x IMM (IMM v1) embedded Baseboard Management Controller (BMC). This vulnerability could allow an unauthenticated user to cause JavaScript code to be stored in the IMM log which may then be executed in the user's web browser when IMM log records containing the JavaScript code are viewed. The JavaScript code is not executed on IMM itself. The later IMM2 (IMM v2) is not affected.

An internal product security audit of Lenovo XClarity Administrator (LXCA) discovered HTTP proxy credentials being written to a log file in clear text. This only affects LXCA when HTTP proxy credentials have been configured. This affects LXCA versions 2.0.0 to 2.3.x.

In various firmware versions of Lenovo System x, the integrated management module II (IMM2)'s first failure data capture (FFDC) includes the web server's private key in the generated log file for support.

In Lenovo systems, SMM BIOS Write Protection is used to prevent writes to SPI Flash. While this provides sufficient protection, an additional layer of protection is provided by SPI Protected Range Registers (PRx). Lenovo was notified that after resuming from S3 sleep mode in various versions of BIOS for Lenovo systems, the PRx is not set. This does not impact the SMM BIOS Write Protection, which keeps systems protected.

A DLL search path vulnerability was reported in Lenovo Bootable Generator, prior to version Mar-2019, that could allow a malicious user with local access to execute code on the system.

An unquoted search path vulnerability was identified in Lenovo Dynamic Power Reduction Utility prior to version 2.2.2.0 that could allow a malicious user with local access to execute code with administrative privileges.
