TITLE

Apple Mac OS X AppleScript Editor code confusing vulnerability

DESCRIPTION

The AppleScript Editor in Mac OS X 10.3.9 does not properly display script code for an applescript: URI, which can result in code that is different than the actual code that would be run, which could allow remote attackers to trick users into executing malicious code via certain URI characters such as NULL, control characters, and homographs. Mac OS X AppleScript editor is prone to a code obfuscation vulnerability. This issue was initially reported in BID 13480 (Apple Mac OS X Multiple Vulnerabilities). Due to the availability of more information, this issue is being assigned a new BID. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have published advisories for 4 security vulnerabilities in Mac OS X that were addressed by Apple Security Update 2005-005, released today. <http://docs.info.apple.com/article.html?artnum=301528>. This email contains brief summaries of the problems. Full details can be found on my web site <http://remahl.se/david/vuln/>. Description: help: URI handler execution of JavaScripts with known paths vulnerability My name: DR004 <http://remahl.se/david/vuln/004/> CVE: CAN-2005-1337 [yes, cool, isn't it ;-)] Summary: The Help Viewer application allows JavaScript and is thus vulnerable to having scripts with arbitrary paths run with the privileges granted to file: protocol URIs. The files can be started with a URI on the form of help:///path/to/file.html. Combined with XMLHttpRequest's ability to disclose arbitrary files, this security bug becomes critcal. Description: Invisible characters in applescript: URL protocol messaging vulnerability My name: DR010 <http://remahl.se/david/vuln/010/> CVE: CAN-2005-1331 Summary: URL Protocol Messaging is a technique used by Script Editor to facilitate sharing of AppleScripts between users. By clicking a link (for example in a web forum), a user can create a new Script Editor document automatically, with text from the query string of the URI. This avoids problems with copying text from the web or manually typing code snippets. However, the technique can be used to trick users into running dangerous code (with embedded control characters), since insufficient input validation is performed. Description: Apple Terminal insufficient input sanitation of x-man- path: URIs vulnerability My name: DR011 <http://remahl.se/david/vuln/011/> CVE: CAN-2005-1342 Summary: Apple Terminal fails to properly sanitize the contents of x- man-path: URIs passed to it. This can lead to execution of arbitrary commands, aided by some of the escape sequences that Terminal supports. Description: Mac OS X terminal emulators allow reading and writing of window title through escape sequences My name: DR012 <http://remahl.se/david/vuln/012/> CVE: CAN-2005-1341 Summary: Apple Terminal (often referred to as Terminal.app) and xterm which both ship with current versions of Mac OS X are vulnerable to a well-known type of attack when displaying untrusted content. Using escape sequences and social engineering attacks it is in some cases possible to trick the user into performing arbitrary commands. I would like to acknowledge the willingness of Apple's Product Security team to cooperate with me in resolving these issues. CERT's assistance has also been helpful. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 SUPPORT COMMUNICATION - SECURITY BULLETIN Document ID: c00600177 Version: 1 HPSBUX02119 SSRT4848 rev.1 - HP-UX Running Motif Applications Remote Arbitrary Code Execution, Denial of Service (DoS) NOTICE: The information in this Security Bulletin should be acted upon as soon as possible.
