Vulnerabilities

Certain Lexmark devices (such as CS310) before 2023-08-25 allow XXE attacks, leading to information disclosure. The fixed firmware version is LW80.*.P246, i.e., '*' indicates that the full version specification varies across product model family, but firmware level P246 (or higher) is required to remediate the vulnerability.

Certain Lexmark devices through 2023-02-19 mishandle Input Validation (issue 2 of 4).

In certain Lexmark products through 2023-01-12, SSRF can occur because of a lack of input validation.

Various Lexmark products through 2022-04-27 allow an attacker who has already compromised an affected Lexmark device to maintain persistence across reboots.

Lexmark products through 2022-02-10 have Incorrect Access Control.

Embedded web server command injection vulnerability in Lexmark devices through 2021-12-07.

The initial admin account setup wizard on Lexmark devices allow unauthenticated access to the “out of service erase” feature.

The Lexmark Universal Print Driver version 2.15.1.0 and below, G2 driver 2.7.1.0 and below, G3 driver 3.2.0.0 and below, and G4 driver 4.2.1.0 and below are affected by a privilege escalation vulnerability. A standard low priviliged user can use the driver to execute a DLL of their choosing during the add printer process, resulting in escalation of privileges to SYSTEM.

The Lexmark Printer Software G2, G3 and G4 Installation Packages have a local escalation of privilege vulnerability due to a registry entry that has an unquoted service path.

A cross-site scripting (XSS) vulnerability in Lexmark Pro910 series inkjet and other discontinued products.

Certain older Lexmark devices (C, M, X, and 6500e before 2018-12-18) contain a directory traversal vulnerability in the embedded web server.

Lexmark Markvision Enterprise (MVE) before 2.4.1 allows remote attackers to execute arbitrary commands by uploading files. (

Various Lexmark products have stored XSS in the embedded web server used in older generation Lexmark devices. Affected products are available in http://support.lexmark.com/index?page=content&id=TE935&locale=en&userlocale=EN_US.

Lexmark printer MS812 and multiple older generation Lexmark devices have a stored XSS vulnerability in the embedded web server. The vulnerability can be exploited to expose session credentials and other information via the users web browser.

In Lexmark Services Monitor 2.27.4.0.39 (running on TCP port 2070), a remote attacker can use a directory traversal technique using /../../../ or ..%2F..%2F..%2F to obtain local files on the host operating system.

Various Lexmark products have an Integer Overflow.

Various Lexmark devices have a Buffer Overflow (issue 1 of 2).

Various Lexmark devices have a Buffer Overflow (issue 2 of 2).

On certain Lexmark devices that communicate with an LDAP or SMTP server, a malicious administrator can discover LDAP or SMTP credentials by changing that server's hostname to one that they control, and then capturing the credentials that are sent there. This occurs because stored credentials are not automatically deleted upon that type of hostname change.

Certain Lexmark CX, MX, X, XC, XM, XS, and 6500e devices before 2019-02-11 allow remote attackers to erase stored shortcuts.

Lexmark Scan To Network (SNF) 3.2.9 and earlier stores network configuration credentials in plaintext and transmits them in requests, which allows remote attackers to obtain sensitive information via requests to (1) cgi-bin/direct/printer/prtappauth/apps/snfDestServlet or (2) cgi-bin/direct/printer/prtappauth/apps/ImportExportServlet.

An exploitable use-after-free exists in the PDF parsing functionality of Lexmark Perspective Document Filters 11.3.0.2400 and 11.4.0.2452. A crafted PDF document can lead to a use-after-free resulting in direct code execution.

An exploitable arbitrary read exists in the XLS parsing of the Lexmark Perspective Document Filters conversion functionality. A crafted XLS document can lead to a arbitrary read resulting in memory disclosure. The vulnerability was confirmed on versions 11.3.0.2228 and 11.3.0.2400

An exploitable out-of-bounds write exists in the Bzip2 parsing of the Lexmark Perspective Document Filters conversion functionality. A crafted Bzip2 document can lead to a stack-based buffer overflow causing an out-of-bounds write which under the right circumstance could potentially be leveraged by an attacker to gain arbitrary code execution.

Lexmark printers with firmware ATL before ATL.021.063, CB before CB.021.063, PP before PP.021.063, and YK before YK.021.063 mishandle Erase Printer Memory and Erase Hard Disk actions, which allows physically proximate attackers to obtain sensitive information via direct read operations on non-volatile memory.
