Lexmark : Security Vulnerabilities, CVEs,

Multiple buffer overflows in Lexmark MarkVision printer driver programs allows local users to gain privileges via long arguments to the cat_network, cat_paraller, and cat_serial commands.

The HTTP server in Lexmark T522 and possibly other models allows remote attackers to cause a denial of service (server crash, reload, or hang) via an HTTP header with a long Host field, possibly triggering a buffer overflow.

Lexmark X1185 printer allows local users to gain SYSTEM privileges by navigating to the "Appearance" dialog and selecting the "Additional styles (skins) are available on the Lexmark web site" option, which launches a web browser that is running with SYSTEM privileges.

Unspecified vulnerability in the Lexmark Printer Sharing LexBce Server Service (LexPPS), possibly 8.29 and 9.41, allows remote attackers to execute arbitrary code via unspecified vectors. NOTE: This information is based on a vague initial disclosure; details will be updated after the grace period has ended.

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.

Lexmark X, W, T, E, C, 6500e, and 25xxN devices before 2011-11-15 allow attackers to obtain sensitive information via a hidden email address in a Scan To Email shortcut.

Lexmark X, W, T, E, and C devices before 2012-02-09 allow attackers to obtain sensitive information by reading passwords within exported settings.

Lexmark Markvision Enterprise before 1.8 provides a diagnostic interface on TCP port 9789, which allows remote attackers to execute arbitrary code, change the configuration, or obtain sensitive fleet-management information via unspecified vectors.

Multiple cross-site scripting (XSS) vulnerabilities on Lexmark W840 through LS.HA.P252, T64x before LS.ST.P344, C935dn through LC.JO.P091, C920 through LS.TA.P152, C53x through LS.SW.P069, C52x through LS.FA.P150, E450 through LM.SZ.P124, E350 through LE.PH.P129, and E250 through LE.PM.P126 printers allow remote authenticated users to inject arbitrary web script or HTML by using (1) SNMP or (2) the Embedded Web Server (EWS) to set the (a) Contact or (b) Location field.

Directory traversal vulnerability in the GfdFileUploadServerlet servlet in Lexmark MarkVision Enterprise before 2.1 allows remote attackers to write to arbitrary files via unspecified vectors.

Directory traversal vulnerability in the ReportDownloadServlet servlet in Lexmark MarkVision Enterprise before 2.1 allows remote attackers to read arbitrary files via unspecified vectors.

Directory traversal vulnerability in the LibraryFileUploadServlet servlet in Lexmark Markvision Enterprise allows remote authenticated users to write to and execute arbitrary files via a .. (dot dot) in a file path in a ZIP archive.

Lexmark Markvision Enterprise before 2.3.0 misuses the Apache Commons Collections Library, leading to remote code execution because of Java deserialization.

Race condition in the initialization process on Lexmark printers with firmware ATL before ATL.02.049, CB before CB.02.049, PP before PP.02.049, and YK before YK.02.049 allows remote attackers to bypass authentication by leveraging incorrect detection of the security-jumper status.

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.

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 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.

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.

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

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 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 code execution vulnerability exists in the image rendering functionality of Lexmark Perceptive Document Filters 11.3.0.2400. A specifically crafted PDF can cause a function call on a corrupted DCTStream to occur, resulting in user controlled data being written to the stack. A maliciously crafted PDF file can be used to trigger this vulnerability.
