Brother MFC-9970CDW 1.10 firmware L devices contain a security bypass vulnerability which allows physically proximate attackers to gain unauthorized access.

There is an improper authorization vulnerability in some Huawei smartphones. An attacker could perform a series of operation in specific mode to exploit this vulnerability. Successful exploit could allow the attacker to bypass app lock. (Vulnerability ID: HWPSIRT-2019-12144) This vulnerability has been assigned a Common Vulnerabilities and Exposures (CVE) ID: CVE-2020-9081.

A security restriction bypass vulnerability has been discovered in Revive Adserver version < 5.0.5 by HackerOne user hoangn144. Revive Adserver, like many other applications, requires the logged in user to type the current password in order to change the e-mail address or the password. It was however possible for anyone with access to a Revive Adserver admin user interface to bypass such check and change e-email address or password of the currently logged in user by altering the form payload.The attack requires physical access to the user interface of a logged in user. If the POST payload was altered by turning the “pwold” parameter into an array, Revive Adserver would fetch and authorise the operation even if no password was provided.

Windows Lock Screen Security Feature Bypass Vulnerability

Windows Boot Manager Security Feature Bypass Vulnerability

A vulnerability in Mitel 6900 Series IP (MiNet) phones excluding 6970, versions 1.8 (1.8.0.12) and earlier, could allow a unauthenticated attacker with physical access to the phone to gain root access due to insufficient access control for test functionality during system startup. A successful exploit could allow access to sensitive information and code execution.

An issue was discovered in TECHView LA5570 Wireless Gateway 1.0.19_T53, allows physical attackers to gain escalated privileges via the UART interface.

An issue in the SharedConfig class of Telegram Android APK v.11.7.0 allows a physically proximate attacker to bypass authentication and escalate privileges by manipulating the return value of the checkPasscode method.

IOMMU page mapping issues on x86 T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Both AMD and Intel allow ACPI tables to specify regions of memory which should be left untranslated, which typically means these addresses should pass the translation phase unaltered. While these are typically device specific ACPI properties, they can also be specified to apply to a range of devices, or even all devices. On all systems with such regions Xen failed to prevent guests from undoing/replacing such mappings (CVE-2021-28694). On AMD systems, where a discontinuous range is specified by firmware, the supposedly-excluded middle range will also be identity-mapped (CVE-2021-28695). Further, on AMD systems, upon de-assigment of a physical device from a guest, the identity mappings would be left in place, allowing a guest continued access to ranges of memory which it shouldn't have access to anymore (CVE-2021-28696).

Inappropriate implementation in Chrome OS lockscreen in Google Chrome on Chrome OS prior to 105.0.5195.52 allowed a local attacker to bypass lockscreen navigation restrictions via physical access to the device.
