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
The embedded HTTP server in multiple Lexmark laser and inkjet printers and MarkNet devices, including X94x, W840, T656, N4000, E462, C935dn, 25xxN, and other models, allows remote attackers to cause a denial of service (operating system halt) via a malformed HTTP Authorization header.
The flood-protection feature in the base, IPDS DLE, Forms DLE, Barcode DLE, Prescribe DLE, and Printcryption DLE components on certain Lexmark laser and inkjet printers and MarkNet devices allows remote attackers to cause a denial of service (TCP outage) by making many passive FTP connections and then aborting these connections.
Stack-based buffer overflow in the base, IPDS DLE, Forms DLE, Barcode DLE, Prescribe DLE, and Printcryption DLE components on certain Lexmark laser printers and multi-function printers allows remote attackers to execute arbitrary code or cause a denial of service (device hang) via a long argument to a PJL INQUIRE command.
A buffer overflow vulnerability has been identified in PostScript interpreter in various Lexmark devices. The vulnerability can be leveraged by an attacker to execute arbitrary code.
A heap corruption vulnerability has been identified in PostScript interpreter in various Lexmark devices. The vulnerability can be leveraged by an attacker to execute arbitrary code.
A memory corruption vulnerability has been identified in PostScript interpreter in various Lexmark devices. The vulnerability can be leveraged by an attacker to execute arbitrary code.
The SE menu contains information used by Lexmark to diagnose device errors. A vulnerability in one of the SE menu routines can be leveraged by an attacker to execute arbitrary code.
Improper Restriction of XML External Entity Reference in various Lexmark printer drivers for Windows allows attacker to disclose sensitive information to an arbitrary URL.
A missing authorization vulnerability in Lexmark Cloud Services badge management allows attacker to reassign badges within their organization
A heap-based buffer overflow vulnerability has been identified in the Postscript interpreter in various Lexmark devices. This vulnerability can be leveraged by an attacker to execute arbitrary code as an unprivileged user.
An untrusted search path vulnerability has been identified in the Embedded Solutions Framework in various Lexmark devices. This vulnerability can be leveraged by an attacker to execute arbitrary code.

A Server-Side Request Forgery (SSRF) vulnerability has been identified in the embedded web server in various Lexmark devices. This vulnerability can be leveraged by an attacker to force the device to send an arbitrary HTTP request to a third-party server. Successful exploitation of this vulnerability can lead to internal network access / potential data disclosure from a device.
Certain Lexmark devices through 2023-02-19 mishandle Input Validation (issue 2 of 4).
An exploitable buffer overflow exists in the XLS parsing of the Lexmark Perspective Document Filters conversion functionality. A crafted XLS document can lead to a stack based buffer overflow resulting in remote code execution.
An exploitable heap overflow vulnerability exists in the Compound Binary File Format (CBFF) parser functionality of Lexmark Perceptive Document Filters library. A specially crafted CBFF file can cause a code execution. An attacker can send a malformed file to trigger this vulnerability.
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.
