In System Management Module (SMM) versions prior to 1.06, an internal SMM function that retrieves configuration settings is prone to a buffer overflow.

In System Management Module (SMM) versions prior to 1.06, a field in the header of SMM firmware update images is insufficiently sanitized, allowing post-authentication command injection on the SMM as the root user.

In System Management Module (SMM) versions prior to 1.06, the SMM web interface for changing Enclosure VPD fails to sufficiently sanitize all input for HTML tags, possibly opening a path for cross-site scripting.

In System Management Module (SMM) versions prior to 1.06, the SMM certificate creation and parsing logic is vulnerable to several buffer overflows.

In System Management Module (SMM) versions prior to 1.06, the SMM certificate creation and parsing logic is vulnerable to post-authentication command injection.

In System Management Module (SMM) versions prior to 1.06, if an attacker manages to log in to the device OS, the validation of software updates can be circumvented.

In System Management Module (SMM) versions prior to 1.06, the FFDC feature includes the collection of SMM system files containing sensitive information; notably, the SMM user account credentials and the system shadow file.

In System Management Module (SMM) versions prior to 1.06, the SMM records hashed passwords to a debug log when user authentication fails.

A write protection lock bit was left unset after boot on an older generation of Lenovo and IBM System x servers, potentially allowing an attacker with administrator access to modify the subset of flash memory containing Intel Server Platform Services (SPS) and the system Flash…

Lenovo Chassis Management Module (CMM) prior to version 2.0.0 utilizes a hardcoded encryption key to protect certain secrets. Possession of the key can allow an attacker that has already compromised the server to decrypt these secrets.

Lenovo Chassis Management Module (CMM) prior to version 2.0.0 allows unauthenticated users to retrieve information related to the current authentication configuration settings. Exposed settings relate to password lengths, expiration, and lockout configuration.

In some Lenovo ThinkServer-branded servers, a command injection vulnerability exists in the BMC firmware download command. This allows a privileged user to download and execute arbitrary code inside the BMC. This can only be exploited by authorized privileged users.

Race condition in the administration-panel web service in IBM System Networking Switch Center (SNSC) before 7.3.1.5 and Lenovo Switch Center before 8.1.2.0 allows remote attackers to obtain privileged-account access, and consequently provide ZipDownload.jsp input containing…

The DB service in IBM System Networking Switch Center (SNSC) before 7.3.1.5 and Lenovo Switch Center before 8.1.2.0 allows remote attackers to obtain sensitive administrator-account information via a request on port 40999, as demonstrated by an improperly encrypted password.

The administration-panel web service in IBM System Networking Switch Center (SNSC) before 7.3.1.5 and Lenovo Switch Center before 8.1.2.0 allows local users to execute arbitrary JSP code with SYSTEM privileges by using the Apache Axis AdminService deployment method to install a…

Race condition in the administration-panel web service in IBM System Networking Switch Center (SNSC) before 7.3.1.5 and Lenovo Switch Center before 8.1.2.0 allows remote attackers to obtain privileged-account access, and consequently provide FileReader.jsp input containing…

The pit_ioport_read in i8254.c in the Linux kernel before 2.6.33 and QEMU before 2.3.1 does not distinguish between read lengths and write lengths, which might allow guest OS users to execute arbitrary code on the host OS by triggering use of an invalid index.

Race condition in Lenovo System Update (formerly ThinkVantage System Update) before 5.06.0034 uses world-writable permissions for the update files directory, which allows local users to gain privileges by writing to an update file after the signature is validated.

Lenovo System Update (formerly ThinkVantage System Update) before 5.06.0034 does not properly validate CA chains during signature validation, which allows man-in-the-middle attackers to upload and execute arbitrary files via a crafted certificate.

The ThinkServer System Manager (TSM) Baseboard Management Controller before firmware 1.27.73476 for ThinkServer RD350, RD450, RD550, RD650, and TD350 does not validate server certificates during an "encrypted remote KVM session," which allows man-in-the-middle attackers to spoof…

The ThinkServer System Manager (TSM) Baseboard Management Controller before firmware 1.27.73476 for ThinkServer RD350, RD450, RD550, RD650, and TD350 allows remote attackers to cause a denial of service (web interface crash) via a malformed HTTP request during authentication.

Lenovo ThinkServer RD350, RD450, RD550, RD650, and TD350 servers before 1.26.0 use weak encryption to store (1) user and (2) administrator BIOS passwords, which allows attackers to decrypt the passwords via unspecified vectors.

Lenovo USB Enhanced Performance Keyboard software before 2.0.2.2 includes active debugging code in SKHOOKS.DLL, which allows local users to obtain keypress information by accessing debug output.

java/android/webkit/BrowserFrame.java in Android before 4.4 uses the addJavascriptInterface API in conjunction with creating an object of the SearchBoxImpl class, which allows attackers to execute arbitrary Java code by leveraging access to the searchBoxJavaBridge_ interface at…

Heap-based buffer overflow in the tvtumin.sys kernel driver in Lenovo Rescue and Recovery 4.20, including 4.20.0511 and 4.20.0512, allows local users to execute arbitrary code via a long file name.

The client in Lenovo System Update before 3.14 does not properly validate the certificate when establishing an SSL connection, which allows remote attackers to install arbitrary packages via an SSL certificate whose X.509 headers match a public certificate used by IBM.

The IBM Lenovo Access Support acpRunner ActiveX control, as distributed in acpcontroller.dll before 1.2.8.0 and possibly acpir.dll before 1.0.0.9 (Automated Solutions 1.0 before fix pack 1), does not properly validate digital signatures of downloaded software, which makes it…
