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.

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.

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.

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

The BIOS implementation on Dell Latitude, OptiPlex, Precision Mobile Workstation, and Precision Workstation Client Solutions (CS) devices with model-dependent firmware before A21 does not enforce a BIOS_CNTL locking protection mechanism upon being woken from sleep, which allows local users to conduct EFI flash attacks by leveraging console access, a similar issue to CVE-2015-3692.

Bytemark Symbiosis before Revision 1322 does not properly validate passwords, which allows remote attackers to gain access to email accounts via an arbitrary password.

Intel Desktop and Intel Mobile Boards with BIOS firmware DQ35JO, DQ35MP, DP35DP, DG33FB, DG33BU, DG33TL, MGM965TW, D945GCPE, and DX38BT allows local administrators with ring 0 privileges to gain additional privileges and modify code that is running in System Management Mode, or access hypervisory memory as demonstrated at Black Hat 2008 by accessing certain remapping registers in Xen 3.3.

Cross-site scripting (XSS) vulnerability in bios.php in PHP Scripts Now President Bios allows remote attackers to inject arbitrary web script or HTML via the rank parameter.

SQL injection vulnerability in bios.php in PHP Scripts Now President Bios allows remote attackers to execute arbitrary SQL commands via the rank parameter.

Intel firmware PE94510M.86A.0050.2007.0710.1559 stores pre-boot authentication passwords in the BIOS Keyboard buffer and does not clear this buffer after use, which allows local users to obtain sensitive information by reading the physical memory locations associated with this buffer.
