CVE’s

Some Kyocera printers (such as the ECOSYS M5526cdw 2R7_2000.001.701) were affected by a buffer overflow vulnerability in multiple parameters of the Document Boxes functionality of the web application that would allow an authenticated attacker to perform a Denial of Service attack, crashing the device, or potentially execute arbitrary code on the device.

All configuration parameters of certain Kyocera printers (such as the ECOSYS M5526cdw 2R7_2000.001.701) were accessible by unauthenticated users. This information was only presented in the menus when authenticated, and the pages that loaded this information were also protected. However, all files that contained the configuration parameters were accessible. These files contained sensitive information, such as users, community strings, and other passwords configured in the printer.

Some Kyocera printers (such as the ECOSYS M5526cdw 2R7_2000.001.701) were affected by multiple buffer overflow vulnerabilities in the IPP service. This would allow an unauthenticated attacker to cause a Denial of Service (DoS), and potentially execute arbitrary code on the device.

Some Kyocera printers (such as the ECOSYS M5526cdw 2R7_2000.001.701) were affected by an integer overflow vulnerability in the arg3 parameter of several functionalities of the web application that would allow an authenticated attacker to perform a Denial of Service attack, crashing the device, or potentially execute arbitrary code on the device.

Some Kyocera printers (such as the ECOSYS M5526cdw 2R7_2000.001.701) were affected by a buffer overflow vulnerability in the okhtmlfile and failhtmlfile parameters of several functionalities of the web application that would allow an unauthenticated attacker to perform a Denial of Service attack, crashing the device, or potentially execute arbitrary code on the device.

Some Kyocera printers (such as the ECOSYS M5526cdw 2R7_2000.001.701) were affected by a buffer overflow vulnerability in the LPD service. This would allow an unauthenticated attacker to cause a Denial of Service (DoS) in the LPD service and potentially execute arbitrary code on the device.

The web application of several Kyocera printers (such as the ECOSYS M5526cdw 2R7_2000.001.701) was affected by Reflected XSS. Successful exploitation of this vulnerability can lead to session hijacking of the administrator in the web application or the execution of unwanted actions.

An elevation of privilege vulnerability exists when Windows improperly handles authentication requests, aka 'Microsoft Windows Elevation of Privilege Vulnerability'. This CVE ID is unique from CVE-2019-1322, CVE-2019-1340.

Some Kyocera printers (such as the ECOSYS M5526cdw 2R7_2000.001.701) did not implement any mechanism to avoid CSRF. Successful exploitation of this vulnerability can lead to the takeover of a local account on the device.

The web application of several Kyocera printers (such as the ECOSYS M5526cdw 2R7_2000.001.701) was affected by Stored XSS. Successful exploitation of this vulnerability can lead to session hijacking of the administrator in the web application or the execution of unwanted actions.
