A security flaw impacting the Lighttpd web server used in baseboard management controllers (BMCs) has remained unpatched by device vendors like Intel and Lenovo, new findings from Binarly reveal....
An almost 6-year-old vulnerability in the Lighttpd web server used in Baseboard Management Controllers has been overlooked by many device vendors, including Intel and Lenovo. Although the vulnerability was addressed in August 2018, the maintainers of Lighthttpd patched it silently in version 1.4.51 without assigning a tracking ID. This led the developers of AMI MegaRAC BMC to miss the fix and fail to integrate it into the product.
Security researchers bypassed Windows Hello fingerprint authentication on Dell Inspiron, Lenovo ThinkPad, and Microsoft Surface Pro X laptops in attacks exploiting security flaws found in the embedded fingerprint sensors. Blackwing Intelligence security researchers discovered vulnerabilities during research sponsored by Microsoft's Offensive Research and Security Engineering to assess the security of the top three embedded fingerprint sensors used for Windows Hello fingerprint authentication.
Qualcomm on Tuesday released patches to address multiple security flaws in its chipsets, some of which could be exploited to cause information disclosure and memory corruption. The five vulnerabilities - tracked from CVE-2022-40516 through CVE-2022-40520 - also impact Lenovo ThinkPad X13s laptops, prompting the Chinese PC maker to issue BIOS updates to plug the security holes.
An analysis of firmware images across devices from Dell, HP, and Lenovo has revealed the presence of outdated versions of the OpenSSL cryptographic library, underscoring a supply chain risk. The firmware development environment, which is in its second iteration, comes with its own cryptographic package called CryptoPkg that, in turn, makes use of services from the OpenSSL project.
PC maker Lenovo has addressed yet another set of three shortcomings in the Unified Extensible Firmware Interface firmware affecting several Yoga, IdeaPad, and ThinkBook devices. "The vulnerabilities allow disabling UEFI Secure Boot or restoring factory default Secure Boot databases: all simply from an OS," Slovak cybersecurity firm ESET explained in a series of tweets.
Lenovo has fixed two high-severity vulnerabilities impacting various ThinkBook, IdeaPad, and Yoga laptop models that could allow an attacker to deactivate UEFI Secure Boot. UEFI Secure Boot is a verification system that ensures no malicious code can be loaded and executed during the computer boot process.
Chinese computer manufacturer Lenovo has issued a security advisory to warn of several high-severity BIOS vulnerabilities impacting hundreds of devices in the various models. CVE-2022-40134: Information leak flaw in the SMI Set Bios Password SMI Handler, allowing an attacker to read SMM memory.
Security researchers have spotted some fresh flaws in Lenovo laptops just months after the vendor patched another batch, with the PC maker fixing a trio of vulnerabilities flagged up by ESET this week. The vulnerabilities reported were buffer overflows in the UEFI firmware.
