Fusion News 3.6.1 allows remote attackers to add user accounts, if the administrator is logged in, via a comment that contains an img bbcode tag that calls index.php with the signup action, which is executed when the administrator's browser loads the page with the img tag.

The strip_tags function in PHP 4.x up to 4.3.7, and 5.x up to 5.0.0RC3, does not filter null (\0) characters within tag names when restricting input to allowed tags, which allows dangerous tags to be processed by web browsers such as Internet Explorer and Safari, which ignore null characters and facilitate the exploitation of cross-site scripting (XSS) vulnerabilities.

The (1) Mozilla 1.6, (2) Firebird 0.7, (3) Firefox 0.8, and (4) Netscape 7.1 web browsers do not properly prevent a frame in one domain from injecting content into a frame that belongs to another domain, which facilitates web site spoofing and other attacks, aka the frame injection vulnerability.

The Phoenix browser in eSeSIX Thintune thin clients running firmware 2.4.38 and earlier allows local users to read arbitrary files via a file:/// URL.

HelpViewer in Mac OS X 10.3.3 and 10.2.8 processes scripts that it did not initiate, which can allow attackers to execute arbitrary code, an issue that was originally reported as a directory traversal vulnerability in the Safari web browser using the runscript parameter in a help: URI handler.

MS Analysis module 2.0 for PHP-Nuke allows remote attackers to obtain sensitive information via a direct request to (1) browsers.php, (2) mstrack.php, or (3) title.php, which reveal the full path in a PHP error message.

Unknown vulnerability in Safari web browser for Mac OS X 10.2.8 related to "the display of URLs in the status bar."

Unknown vulnerability in Safari web browser in Mac OS X 10.2.8 and 10.3.2, with unknown impact.

Opera Web Browser 7.0 through 7.23 allows remote attackers to trick users into executing a malicious file by embedding a CLSID in the file name, which causes the malicious file to appear as a trusted file type, aka "File Download Extension Spoofing."

Internet Explorer 6 SP1 and earlier allows remote attackers to bypass zone restrictions by (1) using the NavigateAndFind method to load a file: URL containing Javascript, as demonstrated by NAFfileJPU, (2) using the window.open method to load a file: URL containing Javascript, as demonstrated using WsOpenFileJPU, (3) setting the href property in the base tag for the _search window, as demonstrated using WsBASEjpu, (4) loading the search window into an Iframe, as demonstrated using WsFakeSrc, (5) caching a javascript: URL in the browser history, then accessing that URL in the same frame as the target domain, as demonstrated using WsOpenJpuInHistory, NAFjpuInHistory, BackMyParent, BackMyParent2, and RefBack, aka the "Script URLs Cross Domain" vulnerability.

Macromedia Flash Player before 7,0,19,0 stores a Flash data file in a predictable location that is accessible to web browsers such as Internet Explorer and Opera, which allows remote attackers to read restricted files via vulnerabilities in web browsers whose exploits rely on predictable names.

Sun Java Runtime Environment (JRE) 1.x before 1.4.2_11 and 1.5.x before 1.5.0_06, and as used in multiple web browsers, allows remote attackers to cause a denial of service (application crash) via deeply nested object arrays, which are not properly handled by the garbage collector and trigger invalid memory accesses.

Buffer overflow in Avant Browser 8.02 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long URL in an HTTP request.

Real Networks RealOne Enterprise Desktop 6.0.11.774, RealOne Player 2.0, and RealOne Player 6.0.11.818 through RealOne Player 6.0.11.853 allows remote attackers to execute arbitrary script in the local security zone by embedding script in a temp file before the temp file is executed by the default web browser.

Internet Explorer 5.01 SP3 through 6.0 SP1 allows remote attackers to access and execute script in the My Computer domain using the browser cache via crafted Content-Type and Content-Disposition headers, aka the "Browser Cache Script Execution in My Computer Zone" vulnerability.

FrontRange GoldMine mail agent 5.70 and 6.00 before 30503 directly sends HTML to the default browser without setting its security zone or otherwise labeling it untrusted, which allows remote attackers to execute arbitrary code via a message that is rendered in IE using a less secure zone.

Multiple cross-site scripting (XSS) vulnerabilities in SquirrelMail before 1.2.11 allow remote attackers to inject arbitrary HTML code and steal information from a client's web browser.

Apple Darwin Streaming Administration Server 4.1.2 and QuickTime Streaming Server 4.1.1 allows remote attackers to execute certain code via a request to port 7070 with the script in an argument to the rtsp DESCRIBE method, which is inserted into a log file and executed when the log is viewed using a browser.

Macromedia Flash Player 6 does not terminate connections when the user leaves the web page, which allows remote attackers to cause a denial of service (bandwidth, resource, and CPU consumption) via the (1) loadMovie or (2) loadSound commands, which continue to execute until the browser is closed.

The browser history feature in Microsoft Internet Explorer 5.5 through 6.0 allows remote attackers to execute arbitrary script as other users and steal authentication information via cookies by injecting JavaScript into the URL, which is executed when the user hits the Back button.
