CRLF injection vulnerability in xterm allows user-assisted attackers to execute arbitrary commands via LF (aka \n) characters surrounding a command name within a Device Control Request Status String (DECRQSS) escape sequence in a text file, a related issue to CVE-2003-0063 and CVE-2003-0071.

The remote Fedora 37 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2023-3746647cc3 advisory.

From Red Hat Security Advisory 2009:0018 :

An updated xterm package to correct a security issue is now available for Red Hat Enterprise Linux 3, 4, and 5.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The xterm program is a terminal emulator for the X Window System.

A flaw was found in the xterm handling of Device Control Request Status String (DECRQSS) escape sequences. An attacker could create a malicious text file (or log entry, if unfiltered) that could run arbitrary commands if read by a victim inside an xterm window.
(CVE-2008-2383)

All xterm users are advised to upgrade to the updated package, which contains a backported patch to resolve this issue. All running instances of xterm must be restarted for the update to take effect.

(CVE-2008-2383)

XTerm evaluated various ANSI Escape sequences so that command execution was possible if an attacker could pipe raw data to an xterm.
(CVE-2008-2383)

(It is usually not recommended to display raw data on an xterm.)

XTerm evaluated various ANSI Escape sequences so that command execution was possible if an attacker could pipe raw data to an xterm.
(CVE-2008-2383) (It is usually not recommended to display raw data on an xterm.)

Support for Matrox G200EV/G200WB cards was added.

The remote host is running a version of Mac OS X 10.5.x that is prior to 10.5.7. 

Mac OS X 10.5.7 contains security fixes for the following products :

  - Apache
  - ATS
  - BIND
  - CFNetwork
  - CoreGraphics
  - Cscope
  - CUPS
  - Disk Images
  - enscript
  - Flash Player plug-in

Paul Szabo discovered that the DECRQSS escape sequences were not handled correctly by xterm. Additionally, window title operations were also not safely handled. If a user were tricked into viewing a specially crafted series of characters while in xterm, a remote attacker could execute arbitrary commands with user privileges.
(CVE-2006-7236, CVE-2008-2382).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

A vulnerability has been discovered in xterm, which can be exploited by malicious people to compromise a user's system. The vulnerability is caused due to xterm not properly processing the DECRQSS Device Control Request Status String escape sequence. This can be exploited to inject and execute arbitrary shell commands by e.g. tricking a user into displaying a malicious text file containing a specially crafted escape sequence via the more command in xterm (CVE-2008-2383).

The updated packages have been patched to prevent this.

New xterm packages are available for Slackware 12.0, 12.1, 12.2, and
-current to fix a security issue.

The remote host is affected by the vulnerability described in GLSA-200902-04 (xterm: User-assisted arbitrary commands execution)

    Paul Szabo reported an insufficient input sanitization when processing     Device Control Request Status String (DECRQSS) sequences.
  Impact :

    A remote attacker could entice a user to display a file containing     specially crafted DECRQSS sequences, possibly resulting in the remote     execution of arbitrary commands with the privileges of the user viewing     the file.
  Workaround :

    There is no known workaround at this time.

This update fixes the following security issue: CRLF injection vulnerability in xterm allows user-assisted attackers to execute arbitrary commands via LF (aka \n) characters surrounding a command name within a Device Control Request Status String (DECRQSS) escape sequence in a text file, a related issue to CVE-2003-0063 and CVE-2003-0071.

An updated hanterm-xf package to correct a security issue is now available for Red Hat Enterprise Linux 2.1.

This update has been rated as having important security impact by the Red Hat Security Response Team.

Hanterm is a replacement for xterm, a X Window System terminal emulator, that supports Hangul input and output.

A flaw was found in the Hanterm handling of Device Control Request Status String (DECRQSS) escape sequences. An attacker could create a malicious text file (or log entry, if unfiltered) that could run arbitrary commands if read by a victim inside a Hanterm window.
(CVE-2008-2383)

All hanterm-xf users are advised to upgrade to the updated package, which contains a backported patch to resolve this issue. All running instances of hanterm must be restarted for the update to take effect.

The remote Redhat Enterprise Linux 4 / 5 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2009:0018 advisory.

  - xterm: arbitrary command injection (CVE-2008-2383)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

SecurityFocus reports :

The xterm program is prone to a remote command-execution vulnerability because it fails to sufficiently validate user input.

Successfully exploiting this issue would allow an attacker to execute arbitrary commands on an affected computer in the context of the affected application.

Paul Szabo discovered that xterm, a terminal emulator for the X Window System, places arbitrary characters into the input buffer when displaying certain crafted escape sequences (CVE-2008-2383 ).

As an additional precaution, this security update also disables font changing, user-defined keys, and X property changes through escape sequences.
