Vulnerability from variot

Embedded web server input sanitization vulnerability in Lexmark devices through 2021-12-07, which can which can lead to remote code execution on the device. plural Lexmark The device contains an input validation vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Lexmark MC3224i printers. Authentication is not required to exploit this vulnerability.The specific flaw exists within the HTTP server. The issue results from the lack of proper validation of a user-supplied string before using it to write to a configuration file. An attacker can leverage this vulnerability to execute code in the context of the www-data user. Lexmark is a line of printers in the United States.

Lexmark has a security vulnerability that stems from the fact that the network system or product does not properly filter special elements in the process of constructing code segments from external input data. An attacker could exploit this vulnerability to generate an illegal code segment that modifies the expected execution control flow of a network system or component

      data: "Embedded web server input sanitization vulnerability in Lexmark devices through 2021-12-07, which can which can lead to remote code execution on the device. plural Lexmark The device contains an input validation vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Lexmark MC3224i printers. Authentication is not required to exploit this vulnerability.The specific flaw exists within the HTTP server. The issue results from the lack of proper validation of a user-supplied string before using it to write to a configuration file. An attacker can leverage this vulnerability to execute code in the context of the www-data user. Lexmark is a line of printers in the United States. \n\r\n\r\nLexmark has a security vulnerability that stems from the fact that the network system or product does not properly filter special elements in the process of constructing code segments from external input data. An attacker could exploit this vulnerability to generate an illegal code segment that modifies the expected execution control flow of a network system or component",
