Lenovo : Security Vulnerabilities Published In 2016

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.

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.

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.

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."

Lenovo BIOS EFI Driver allows local administrators to execute arbitrary code with System Management Mode (SMM) privileges via unspecified vectors.

Lenovo Solution Center (LSC) before 3.3.003 allows local users to execute arbitrary code with LocalSystem privileges via vectors involving the LSC.Services.SystemService StartProxy command with a named pipe created in advance and crafted .NET assembly.

The StopProxy command in LSC.Services.SystemService in Lenovo Solution Center before 3.3.003 allows local users to terminate arbitrary processes via the PID argument.

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.

Cross-site scripting (XSS) vulnerability in Lenovo SHAREit before 3.5.98_ww on Android before 4.4 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors, aka "Universal XSS (UXSS)."

Lenovo SHAREit before 3.5.98_ww on Android before 4.2 allows remote attackers to have unspecified impact via a crafted intent: URL, aka an "intent scheme URL attack."

UpdateAgent in Lenovo Accelerator Application allows man-in-the-middle attackers to execute arbitrary code by spoofing an update response from susapi.lenovomm.com.

Lenovo Fingerprint Manager before 8.01.57 and Touch Fingerprint before 1.00.08 use weak ACLs for unspecified (1) services and (2) files, which allows local users to gain privileges by invalidating local checks.

The Wifi hotspot in Lenovo SHAREit before 3.5.48_ww for Android, when configured to receive files, does not require a password, which makes it easier for remote attackers to obtain access by leveraging a position within the WLAN coverage area.

The Wifi hotspot in Lenovo SHAREit before 3.2.0 for Windows, when configured to receive files, has a hardcoded password of 12345678, which makes it easier for remote attackers to obtain access by leveraging a position within the WLAN coverage area.

The Wifi hotspot in Lenovo SHAREit before 3.2.0 for Windows allows remote attackers to obtain sensitive file names via a crafted file request to /list.

Lenovo SHAREit before 3.2.0 for Windows and SHAREit before 3.5.48_ww for Android transfer files in cleartext, which allows remote attackers to (1) obtain sensitive information by sniffing the network or (2) conduct man-in-the-middle (MITM) attacks via unspecified vectors.

Cisco IOS 15.3 and 15.4, Cisco IOS XE 3.8 through 3.11, and Cisco Unified Communications Manager allow remote attackers to cause a denial of service (device reload) via malformed SIP messages, aka Bug ID CSCuj23293.

The IKEv2 implementation in Cisco IOS 15.0 through 15.6 and IOS XE 3.3 through 3.17 allows remote attackers to cause a denial of service (device reload) via fragmented packets, aka Bug ID CSCux38417.

The management interface in LenovoEMC EZ Media & Backup (hm3), ix2/ix2-dl, ix4-300d, px12-400r/450r, px6-300d, px2-300d, px4-300r, px4-400d, px4-400r, and px4-300d NAS devices with firmware before 4.1.204.33661 allows remote attackers to obtain sensitive device information via unspecified vectors.
