VAR-201805-0171
Vulnerability from variot - Updated: 2023-12-18 13:48Some Lenovo System x server BIOS/UEFI versions, when Secure Boot mode is enabled by a system administrator, do not properly authenticate signed code before booting it. As a result, an attacker with physical access to the system could boot unsigned code. plural Lenovo System Product BIOS Contains an authentication vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. LenovoFlexSystemx240M5 and so on are all Lenovo's server equipment. Multiple Lenovo System x Servers are prone to a local authentication-bypass vulnerability. An attacker can exploit this issue to bypass the authentication mechanism and perform unauthorized actions. This may lead to further attacks

"data": "Some Lenovo System x server BIOS/UEFI versions, when Secure Boot mode is enabled by a system administrator, do not properly authenticate signed code before booting it. As a result, an attacker with physical access to the system could boot unsigned code. plural Lenovo System Product BIOS Contains an authentication vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. LenovoFlexSystemx240M5 and so on are all Lenovo\u0027s server equipment. Multiple Lenovo System x Servers are prone to a local authentication-bypass vulnerability. \nAn attacker can exploit this issue to bypass the authentication mechanism and perform unauthorized actions. This may lead to further attacks",
